OPERATION
“B” TYPE
NORMAL (OUTDOOR) CONDENSER - De-energized
See Figure 1. With the pilot valve de-energized, high side pressure
is prevented from entering the cavity above the piston assembly.
At the same time, the upper pilot port is open to suction pressure.
The resulting pressure differential across the piston moves the
piston-seat assembly to close the reclaim condenser port (upper
main port). In this mode, the refrigerant flows to the normal con-
denser. The pilot valve opens the cavity above the piston to suc-
tion. This allows the reclaim condenser to be pumped out through
a small bleed hole in the piston. The pump out process reduces the
reclaim condenser to suction pressure. Once suction pressure is
reached, the flow through the bleed hole in the piston stops. There
is no high to low side bleed with continued operation in the nor-
mal condenser mode. For a more efficient pump out of the reclaim
condenser, a normally open solenoid valve can be added to the
lowest physical location of the reclaim coil to remove liquid.
“C” TYPE
NORMAL (OUTDOOR) CONDENSER - De-energized
With the pilot valve de-energized, high side pressure is prevented
from entering cavity above the piston-seat assembly. At the same
time the upper pilot port is opened to suction pressure. The result-
ing pressure differential across the piston moves the piston-seat
assembly to close the reclaim (upper) main port, thereby eliminat-
ing high to low side bleed and the resulting capacity loss with the
system in the normal condenser mode.
“B” AND “C” TYPE
RECLAIM (REHEAT) CONDENSER - Energized
When the pilot valve is energized, high side pressure is permitted
to flow through the lower pilot port at the same time the upper
pilot port is closed to suction. High side pressure build up on top
of the piston moves the piston-seat assembly to close the normal
condenser port and open the reclaim (upper) main port. With the
upper pilot port closed, there is no high to low side bleed and
resulting capacity loss with the system in the reclaim mode.
Valves using the MKC-1 coil may be used on fluids or gases where
the temperature does not exceed 240°F, while the valve ambient is
120°F. The coil is Underwriters Laboratory Class F rated.

INSTALLATION
PIPING SUGGESTIONS
Valves must be installed in a horizontal or vertical position with
the coil level with or above the valve body. Install Heat Reclaim
Valves so the connections are in the proper flow direction as
shown in Figure 2.
Figure 3, page 4, shows piping schematics only to illustrate the
general installation of the Heat Reclaim Valves. Sporlan recom-
mends that recognized piping references be consulted for assis-
tance in piping procedures. Sporlan is not responsible for system
design, any damage resulting from system design, or for misap-
plication of its products.
Proper support of heat reclaim valves is essential. Concentrated
stresses resulting from thermal expansion or compressor vibra-
tions can cause fatigue failure of tubing, elbows and valve fittings.
Fatigue failures can also result from vapor propelled liquid slug-
ging, and condensation induced shock. The use of piping brackets
close to each of the three way valve fittings is recommended.

Bulletin 30-21 / Page 3
Wiring of single compressor units may require the use of relays
to prevent high to low side bleed during periods when the com-
pressor is not circulating refrigerant. This is necessary to prevent
refrigerant migration to the low side of the system where it may
condense into liquid and damage system components when the
compressor restarts.
It is always a good idea to check with the equipment manufac-
turer for recommendations on the application of heat reclaim
on the specific type of equipment. It is necessary to adhere to
local piping and electrical codes that apply to each applica-
tion. For complete product information, refer to Bulletin 30-10
and 30-10-1.
TYPICAL WIRING SCHEMATICS & ELECTRICAL CONSIDERATIONS
B5D, 8D, 12D or 16D SINGLE COMPRESSOR SYSTEMS
When employing heat reclaim on a refrigeration system, the addi-
tion of head pressure controls is important not only to maintain
liquid pressure at the expansion valve inlet, but also to assure the
availability of quality hot gas at the reclaim heat exchanger.
See Sporlan Bulletin 90-30, Head Pressure Control Valves for
high and low ambient stability. When low ambient conditions are
encountered during fall-winter-spring operation, the Sporlan head
pressure controls hold back liquid refrigerant so a portion of the
condenser surface is inactive. This results in a rise in condensing
pressure.
NOTE: To calculate additional charge required for head
pressure control, see Bulletin 30-20, or Bulletin 90-30-1.
HEAD PRESSURE CONTROL for RECLAIM SYSTEMS
“B” Type - PUMP DOWN or
ELECTRIC DEFROST with PUMP DOWN (unit off)
When the pump down control is energized, relay coil is energized. This
allows the heating to control the 3-Way Heat Reclaim Valve operation.
When the pump down control is de-energized, the normally closed contact
is closed. This bypasses the heating to energize the coil and shut off the
valve’s bleed to suction.

SERVICE
TYPICAL MALFUNCTIONS
There are only three possible malfunctions: 1. Coil burnout. 2. Failure to shift to Reclaim Mode. 3. Failure to shift
to Normal Mode. Each is discussed below:
COIL BURNOUT
Coil burnouts are extremely rare unless caused by one of the
following:
1. Improper electrical characteristics.
2. Continuous over-voltage, more than 10%.
3. Under-voltage of more than 15%. This applies only if the oper-
ating conditions are such that the reduced MOPD causes stall-
ing of the plunger, which results in excessive current draw.
4. Incomplete magnetic circuit due to the omission of the plunger
assembly during reassembly.
5. Mechanical interference with movement of plunger which may
be caused by a deformed enclosing tube.
6. Coil energized while not installed on a valve.
FAILURE TO SHIFT TO RECLAIM MODE
1. Coil burnout (see coil burnout at left).
2. MOPD greater than specifications.
3. Restricted high pressure pilot connection.
4. May not have allowed sufficient time to pump out the reclaim
coil while in the normal mode.
FAILURE TO SHIFT TO NORMAL MODE
1. Stray voltage holding plunger up.
2. Restricted, closed service valve, or capped suction connection
on pilot.
Figure 3
TYPICAL PIPING SCHEMATICS
Use normally open solenoid valve and piping if pump
out is required and “C” model Heat Reclaim Valve is
used, see note 4.
This check valve required if lowest operating ambient
temperature is lower than evaporator temperature.
Restrictor 2449-004 may be required to control pump
out rate on inactive condenser.
Pilot suction line must be open to common suction
whether or not Heat Reclaim Coil is installed at time
of installation and regardless of Heat Reclaim Valve
model/type.
Proper support of heat reclaim valves is essential.
Concentrated stresses resulting from thermal expan-
sion or compressor vibrations can cause fatigue failure
of tubing, elbows and valve fittings. Fatigue failures
can also result from vapor propelled liquid slugging,
and condensation induced shock. The use of piping
brackets close to each of the three way valve fittings is
recommended.

TYPES 8D-SC, 12D-SC & 16D-SC 3-WAY SPLIT CONDENSER VALVES
The Split Condenser Valves are a relatively simple modification
of the standard Heat Reclaim Valves. Figure 7 shows that the
Split Condenser Valves only use the upper port; the lower port is
always open. The location of the seat disc has been optimized such
that when the valve is in the two condenser mode, the flow is split
evenly between the two condensers.
The pilot valve is different from the standard heat reclaim valve.
It is normally open to high pressure.
OPERATION
“B” and “C” TYPE
TWO CONDENSER MODE - De-energized
See Figure 4. With the pilot valve de-energized, high side pressure 1
is permitted to flow through the lower pilot port at the same time the
upper pilot port is closed to suction 2. High side pressure 1built on
top of the piston moves the piston-seat assembly down to evenly split
the flow between the two condensers. The piston-seat assembly is
held in place by a plate located in the Condenser A connection. This
plate is designed to limit restriction through that port. With the upper
pilot port closed, there is no high to low side bleed and no resulting
capacity loss with the system in the two condenser mode.
Valves using the MKC-1 coil may be used on fluids or gases where
the temperature does not exceed 240°F, while the valve ambient is
120°F. The coil is Underwriters Laboratory Class F rated.
NOTE: If the pressure in your idle Condenser B is less than the
suction pressure that the suction connection of the valve is con-
nected to, you may have charge migration back into your idle
Condenser B. A small check valve in the suction pilot line can be
used to prevent this.
“B” (Bleed) TYPE
SINGLE CONDENSER MODE - Energized
See Figure 5. With the pilot valve energized, high side pressure 1
is prevented from entering the cavity above the piston-seat assem-
bly. At the same time the upper pilot port is opened to suction
pressure 2. This opens the cavity above the piston-seat assembly
to suction pressure 2. The cavity below the piston is exposed to
high pressure. The resulting pressure differential across the piston
moves the piston-seat assembly up to close the upper (Condenser
B) port. We use a solid piston ring on the piston, thereby elimi-
nating high to low side bleed around the piston. When the upper
pilot port opens, Condenser B is pumped out through a small bleed
hole in the piston. When Condenser B has been pumped out and
reduced to suction pressure, all flow ceases, thus eliminating high
to low side bleed and the resulting capacity loss that may occur
with the system in the single condenser mode.
“C” (No Bleed) TYPE
SINGLE CONDENSER MODE - Energized
See Figure 5. With the pilot valve energized, high side pressure
1is prevented from entering the cavity above the piston-seat
assembly. At the same time the upper pilot port is opened to suction
pressure 2. This opens the cavity above the piston-seat assembly to
suction pressure 2. The cavity below the piston is exposed to high
pressure. The resulting pressure differential across the piston moves
the piston-seat assembly up to close the upper (Condenser B) port.
We use a solid piston ring on the piston thereby eliminating high to
low side bleed around the piston and the resulting capacity loss that
may occur with the system in the single condenser mode.
INSTALLATION
PIPING SUGGESTIONS
Valves must be installed in a horizontal or vertical position with
the coil level with, or above the valve body. Install Split Condenser
Valves so the connections are in the proper flow direction as shown
in Figure 7.
Q Pilot suction line must be open to common suction
regardless of Split Condenser Valve model/type.
W Proper support of the Split Condenser Valves, espe-
cially the larger models, is essential because of possible
vibrations of the piping and/or their location on the
compressor racks. (For example, a bracket located 2-3”
from the 16D Discharge and Condenser B socket solder
joints is recommended.)
E Restrictor, part no. 2449-004, may be used to control
pump out rate on inactive condenser.

INSTALLATION
CAUTION: The valve body must be wrapped with a wet cloth
while soldering to avoid damage to synthetic internal parts.
While the valve’s steel body construction will help avoid over-
heating of internal parts due to conduction, convection of heat
up through the tubing and valve body while making bottom
connections can damage the internal parts. If possible bench
assemble the valve utilizing stub tubes in a horizontal plane.
Cool the valve body thoroughly after making each connection.

The Type 180 Solenoid Pilot Control
offers three outstanding features for
refrigeration applications:
• Costs less, more economical
to install.
• Only one size.
• Assures positive shut-off of liquid line.
The 180 Solenoid Pilot Control is available as a supplementary
device to Sporlan Thermostatic Expansion Valves. It is used in
place of large capacity solenoid valves for positive shut-off of
liquid lines. Since only one size is necessary it costs less and is
more economical to install.
The Solenoid Pilot Control does not directly close the liquid line,
but acts on the thermostatic expansion valve causing the expan-
sion valve to close. The 180 is installed in the external equalizer
line of the thermostatic expansion valve and has a third 1/4” con-
nection from the liquid line.
OPERATION
To understand the operation of the 180 Solenoid Pilot Control, it
is important to review the principle of operation of a thermostatic
expansion valve. There are three fundamental pressures involved
in the operation of any thermostatic expansion valve. They are: Q
bulb pressure; Wevaporator pressure; and, Espring pressure, as
shown in Figure 8.
The bulb pressure acts on one side of the diaphragm tending to
open the valve. The evaporator pressure acts on the opposite side
of the diaphragm tending to close the valve, and the spring pres-
sure assists in closing the valve. A variation of any one of the
three pressures changes the amount of opening of the valve. In
normal operation of the valve, these pressures tend to establish
a point of equilibrium to maintain a constant superheat at the
outlet of the evaporator. However, when an abnormal pressure is
introduced which upsets the equilibrium, another effect may be
accomplished. The principle upon which the 180 Solenoid Pilot
Control influences the expansion valve action is by the creation
of a pressure under the valve diaphragm, which is higher than the
bulb pressure. This is how it is accomplished.
The Type 180 has two ports in the valve body — one high pres-
sure and one low pressure. When the solenoid coil is energized,
the plunger moves upward sealing off the high-pressure port.
With the high pressure excluded from the pilot control, true suc-
tion pressure acts on the underside of the expansion valve dia-
phragm through the equalizer line and the low pressure port. This
is illustrated in Figure 9. When the solenoid coil is de-energized,
the low pressure port is closed, thereby closing the equalizer
line from the valve to the suction line. The high pressure port is
open and liquid line pressure is applied to the underside of the
thermostatic expansion valve diaphragm. This high-side pres-
sure instantly overcomes the bulb pressure and supplements of
the valve spring, immediately closing the port of the expansion
valve. See Figure 10.

Upon re-energizing the solenoid coil, the low pressure port of the
180 opens and allows instantaneous relief of pressure under the
thermostatic expansion valve diaphragm and normal operation of
the thermostatic expansion valve.
APPLICATION
The Type 180 Solenoid Pilot Control may be connected to
any number of thermostatic expansion valves as large as those
nominally rated at 132 tons on Refrigerant 134a and 180 tons on
Refrigerant 22. Thus one Solenoid Pilot Control simultaneously
controls the action of all expansion valves on one evaporator or
system of evaporators. See Figure 11.
NOTE: Since the thermostatic expansion valve Types
V and W have an extended neck between the thermo-
static element and the valve body, a relatively large
quantity of liquid refrigerant resides at this point during
the off-cycle (Type 180 de-energized). Upon re-energiz-
ing the Type 180 control this liquid must boil off if the
TEV is installed so that the “neck” volume is NOT free
draining. The consequence of such an arrangement is
chilling of the thermostatic element and possible gas
charge condensation or migration.
Therefore, we recommend that Types V or W thermo-
static expansion valves (with gas or Type “P” ther-
mostatic charges), when installed with the Type 180
solenoid pilot control, be placed in an upright position
and at a point above the suction line so that the volume
under the diaphragm is free draining.
The Solenoid Pilot Control is actuated in the same manner as a liq-
uid line solenoid valve, e.g. with a thermostat, a pressure switch,
or by manual control. Since the Type-180 design requires that the
liquid line pressure during the off-cycle be slightly higher than
the expansion valve bulb pressure, certain types of applications
require special precautions.
COMFORT COOLING APPLICATIONS
Sporlan thermostatic expansion valves for comfort cooling
applications are generally supplied with Type P air condition-
ing charged thermostatic elements. These charges limit the
maximum operating or opening pressure during the off-cycle, as
well as during the running cycle. The table lists these standard
maximum operating pressures at an approximate 60°F saturated
evaporator temperature.
Therefore, during the off-cycle the receiver ambient temperature
needs to be only slightly higher, 65°F or more, to maintain a
higher liquid line pressure and to insure satisfactory Solenoid Pilot
Control operation.
COMMERCIAL OR LOW TEMPERATURE
REFRIGERATION APPLICATIONS
This type of application requires that the expansion valve and sen-
sor bulb be installed within the refrigerated space, so the bulb tem-
perature will be the same as the evaporator during the off-cycle.
Not only will this prevent compressor flood-back on start-up, but it
will help insure a liquid line pressure higher than the bulb pressure
to keep the expansion valve closed tight during the off-cycle.
COMFORT COOLING APPLICATION (Intermittent Operation)
In certain locales during mild weather, wide variations between
night and day temperatures can create unusual system pressure
conditions. This occurs when the receiver, hence the liquid line
pressure, falls below the maximum thermostatic expansion valve
operating pressures listed above. This is liable to occur when the
receiver is located on the outside of the building or is subjected to
unusually low ambient temperatures. Proper attention to receiver
location can minimize the possibility.
OTHER APPLICATIONS
On other applications where the Solenoid Pilot control may be
applied, care must be exercised to maintain the correct liquid line
– expansion bulb pressure relationship. If the expansion valve bulb
is located near heating coils or any other location warmer than the
receiver location, trouble may occur. During the off-cycle, the bulb
pressure for expansion valves with thermostatic charges other than
the Type P air conditioning charge will rise and open the valve.
This will tend to flood the evaporator; and, if the compressor is
on pressure control, cause it to run for a short period of time when
cooling is not required. Therefore, proper attention to component
location is important to insure correct operation of the Type 180
Solenoid Pilot Control.
RECOMMENDATIONS
Where the unusual conditions exist as previously described,
and where normal location precautions are not feasible, Sporlan
recommends that a conventional liquid line solenoid valve be
installed instead of the Type 180 Solenoid Pilot Control.
All refrigeration and air conditioning systems should be protected
from moisture and other system contaminants by the Sporlan
Catch-All®Filter Drier. When using the Type 180 Solenoid Pilot
Control, the expansion valve is used to shut off the liquid line
in place of a standard liquid line solenoid valve. Therefore, it is
essential that the system be free of these contaminants which might
prevent the thermostatic expansion valve from seating tight.
On double-ported thermostatic expansion valves, such as Sporlan’s
Types V and W, the chance of dirt causing leakage is increased
since either port could be partially blocked open. If this occurs,
the leakage would be even greater since both ports would leak

because the seating discs operate on the same shaft. Therefore,
an adequately sized Catch-All®should be installed ahead of the
thermostatic expansion valve for complete protection.
The Type 180 Solenoid Pilot Control is not recommended for
application with other makes of thermostatic expansion valves.
The reason is that Sporlan diaphragm assemblies are specially
designed to withstand the admission of high side pressure through
the external equalizer connection.
The Type 180 may be installed either upright or on its side.
However, it should not be mounted with the coil housing below
the valve body.
INSTALLATION
In addition to first cost, flexibility of the Type 180 offers an instal-
lation savings. Standard 1/4” soft copper tubing is the only tubing
required for the three valve connections as shown in Figure 12. A
C-032-F Catch-All®Filter Drier is furnished with each Type 180,
since protection of the valve ports from system contaminants is
important for proper operation.
ELECTRICAL
For normal summer operation of air conditioning systems, the
Type 180 Solenoid Pilot Control may be energized through any
actuating device such as a thermostat, a micro-switch, or a manual
switch. The compressor can be operated separately through the
magnetic starter, wired with a low pressure cut-out switch for
pump down control.
If it is necessary to shut down a system for a long period, the main
liquid line or receiver valve should be closed before de-energiz-
ing the entire system at the main electrical service switch. This
will protect against compressor floodback if any of the unusual
pressure conditions mentioned in the Application section occur
during shutdown.

SERVICE
The Type 180 Solenoid Pilot Control can not be taken apart in the
field. To properly analyze suspected trouble on an installation, it
is advisable to install a pressure gauge by means of a “T” fitting
in the external equalizer connection to the thermostatic expansion
valve, as shown in Figure 12.
By successively opening and closing the circuit to the Pilot
Control only, with the refrigeration system and circulating fans
or pumps in operation, variations approximating condensing pres-
sure and suction pressure should be observed on this gauge.
A. If pressure does not build up rapidly to condensing pressure
when the Pilot Control is de-energized, proceed as follows:
1. Make certain that the electrical circuit has been broken to
the Pilot Control. Since the actuating device is generally
at a remote point, we suggest that a means for temporarily
interrupting the current be made near the valve installation
to facilitate servicing the equipment.
2. Check to see that no restriction exists and pressure is
ahead of both the Solenoid Pilot Control and the C-032-F
Catch-All®Filter-Drier.
3. Check to ascertain that the low pressure port is closing
tightly. A leak in many instances can be detected by a
much cooler line from the Pilot Control to the suction line
than the liquid inlet line of the control. A further check can
be made by removing the suction line connection at the
Pilot Control and temporarily plugging it. No leak should
be indicated at the suction fitting of the Pilot Control.
4. In the event that full liquid line pressure is available and
the bottom port is NOT leaking, then it is necessary to
replace the Pilot Control valve.
B. If the Pilot Control functions satisfactorily, then the thermo-
static expansion valve should be checked. Various causes
could be the reason for operation difficulties: pushrod packing
leak, seat leak, diaphragm failure, and several others. For a
complete service analysis on thermostatic expansion valves,
refer to Bulletin 10-11.

INSTALLATION PRECAUTIONS
1. Do not attempt installation of the valve before pumping the
entire system down.
2. The solenoid coil must not be energized unless it is installed on
the valve. To do so would cause coil to overheat and burn out.
3. The solenoid coil should be fused in accordance with local codes.
4. If a service valve is installed ahead of a solenoid valve, it
should be closed during service procedures. Do not use a
solenoid valve as a safety shutoff while making repairs to the
system. Be sure there is no liquid in the line between the service
and solenoid valves when they are in the closed position that
could create dangerous hydraulic pressures.
5. Do not twist the valve assembly by pulling or pushing on the
enclosing tube or coil assembly.
6. Do not carry a coil assembly or complete valve by the coil
leads. This could damage the coil and cause a coil burnout.
7. Electrically ground the valve body. Typically this is done
through the fluid piping or the electrical conduit.
8. Before energizing the valve, verify that the supply voltage and
frequency matches the solenoid coil marking.
SOLDERING PRECAUTIONS
Solder connections on Sporlan Heat Reclaim Valves are copper.
Any of the commonly used types of solder are satisfactory with
these materials. Regardless of the type of solder used, it is important
to avoid over-heating the valve. Extreme care should be taken
when brazing connections to avoid damage to internal
synthetic parts. The torch tip should be large enough to avoid
prolonged heating of the connection during the brazing operation.
Overheating can also be minimized by directing the flame away
from the valve body. Cool body thoroughly after making
each connection. As an extra precaution, a wet cloth may be
wrapped around the valve body during the soldering operation.
CAUTION: When installing 1/4” flare pilot line connections,
flare body MUST be supported with another wrench. On the 5D
valve, the pilot valve body MUST be supported when tightening
the 1/4” flare connection. Failure to do either of the above
may cause leaks or valve damage.
WIRING
Check the electrical specifica-
tions of the coil to be sure that
they correspond to the available
electrical service. See page 3
for typical wiring schematics
for single compressor systems.
The 1/2” BX conduit connection of junction box on the coil of
Heat Reclaim Valves may be rotated to any position by loosen-
ing the coil screw. Valves with four-wire dual voltage coil have
a wiring diagram decal (see diagram above) on the coil housing
or bracket. This illustrates which wires to connect for either
120, 208, or 240 volt operation. Wiring and fusing (when used)
must comply with prevailing local and national wiring codes and
ordinances.

The parts kit contains two different gaskets for the pilot valve.
Which ones are used depends on the pilot valve design.
The Tetraseal, part #641-6 is a flexible gasket and is used on
design “AA” valves. These valves can be identified by the square
groove on the bottom of the pilot valve.
The bottom of the pilot valve on the design “BB” valve is machined
flat to accomodate the metal “Wolverine” gasket part #14000-5.
