3-Way Valves
INSTALLATION AND SERVICING INSTRUCTIONS
SD-114 / 122013
GENERAL INFORMATION
Installation Precautions
1. Do not attempt installation of the valve before
pumping the entire system down. Make abso-
lutely certain system pressure is no more than 2
or 3 psi above atmospheric pressure.
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 proce-
dures. 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. Do not carry the valve by
the pilot tube. This could cause damage to the
flare (SAE) joint, creating an external leak.
7. Electrically ground the valve body. Typically
this is done through the fluid piping or the elec-
trical conduit.
8. Before energizing the valve, verify that the sup-
ply 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 sol-
der 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 dam-
age 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. As an extra
precaution, a wet cloth may be wrapped around the
body. Cool body thoroughly after making each
connection. As an extra precaution, a wet cloth
may be wrapped around the body during the
soldering operation.
CAUTION: When installing 1/4” flare pilot line
connections, flare body MUST be supported with
another wrench. On the B5D 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 specifications of the coil to be
sure that they correspond to the available electrical
service. See page 4 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 loosening the coil screw. Valves
with four-wire dual voltage coil have a wiring dia-
gram decal (see diagram below) 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 prevail-
ing local and national wiring codes and ordinances.

Installation
PIPING SUGGESTIONS
Valves may be installed in a horizontal or vertical
position. The coil must be level with or above the
valve body. Install Heat Reclaim Valves so the con-
nections are in the proper flow direction.
Figure 1 shows piping schematics only to illus-
trate the general installation of the Heat Reclaim
Valves. Sporlan recommends that recognized piping
references be consulted for assistance in piping
procedures. Sporlan is not responsible for system
design, any damage resulting from system design,
or for misapplication of its products.
Proper support of heat reclaim valves is essen-
tial. Concentrated stresses resulting from thermal
expansion 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.
Typical Piping Schematics
Figure 1
Q Use normally open solenoid valve and piping if pump out is required and “C” model Heat Reclaim Valve is used,
see note 4. Or, if a normally closed valve can be used then use XSP-10. It has a 0.031” orifice, this may eliminate
use of cap tube or Sporlan Restrictor 2449-004.
W This check valve required if lowest operating ambient temperature is lower than evaporator temperature.
E Restrictor 2449-004 may be required to control pump out rate on inactive condenser.
R Pilot suction line must be open to common suction whether or not Heat Reclaim Coil is installed at time of instal-
lation and regardless of Heat Reclaim Valve model/type.
T Proper support of heat reclaim valves is essential. Concentrated stresses resulting from thermal expansion or com-
pressor 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.

“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 con-
tact is closed. This bypasses the heating to energize the coil and shut
off the valve’s bleed to suction.

Wiring of single compressor units may require
the use of relays to prevent high to low side bleed
during periods when the compressor is not cir-
culating 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 equip-
ment manufacturer 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
application. For complete product information,
refer to Bulletin 30-20.
Typical Wiring Schematics & Electrical Considerations
SINGLE COMPRESSOR SYSTEMS
Head Pressure Control for Reclaim
Systems
When employing heat reclaim on a refrigeration
system, the addition 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.
NOTE: To calculate additional charge required
for head pressure control, see Bulletin 30-20.
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 typical malfunction 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 operating conditions are such that the
reduced MOPD causes stalling 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 section on page 4).
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 suc-
tion connection on pilot.
3-WAY SPLIT CONDENSER VALVES
Types 8D-SC, S8D-SC, 12D-SC, S12D-SC,
16D-SC, S16D-SC
The Split Condenser Valves are a relatively simple
modification of the standard Heat Reclaim Valves.
Figure 3 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 opti-
mized such that when the valve is in the two con-
denser 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.
Installation
ELECTRICAL
Energize for condenser A operation. De-Energize
for both A & B condenser operation. Install Split
Condenser Valves so the connections are in the
proper flow direction as shown in Figure 3.
PIPING SUGGESTIONS
Figure 2 shows a piping schematic to illustrate the
general installation of the Split Condenser Valves.
Sporlan recommends that recognized piping refer-
ences be consulted for assistance in piping proce-
dures. Sporlan is not responsible for system design,
any damage resulting from system design, or for
misapplication of its products.
Proper support of Split Condenser Valves, espe-
cially the larger models, is essential because of pos-
sible vibrations of the piping and/or their location
on the compressor racks. (For example, a bracket
located 2 to 3 inches from the 16D Discharge and
Condenser B socket solder joints is recommended.)
SOLENOID PILOT
CONTROL VALVE
Type 180
The Type 180 has two ports
in the valve body — one
high pressure and one low
pressure. When the sole-
noid coil is energized, the
plunger moves upward sealing off the high-pressure
port. With the high pressure excluded from the pilot
control, true suction pressure acts on the under-
side of the expansion valve diaphragm through
the equalizer line and the low pressure port. This
is illustrated in Figure 4. 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 pressure instantly overcomes the bulb pressure
and supplements of the valve spring, immediately
closing the port of the expansion valve.
Upon re-energizing the solenoid coil, the low pres-
sure port of the 180 opens and allows instantaneous
relief of pressure under the thermostatic expansion
valve diaphragm and normal operation of the ther-
mostatic expansion valve.
RECOMMENDATIONS
All refrigeration and air conditioning systems
should be protected from moisture and other sys-
tem 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.
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 installation savings. Standard 1/4”
soft copper tubing is the only tubing required for
the three valve connections. A C-032-F Catch-All
Filter-Drier is furnished with each Type 180, since
protection of the valve ports from system contami-
nants 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-energizing the entire system at
the main electrical service switch. This will protect
against compressor floodback if any unusual pres-
sure conditions occur during shutdown.
SERVICING SUGGESTIONS
The Type 180 Solenoid Pilot Control cannot be
taken apart in the field. To properly analyze sus-
pected 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 thermo-
static expansion valve.
By successively opening and closing the circuit to
the Pilot Control only, with the refrigeration sys-
tem and circulating fans or pumps in operation,
variations approximating condensing pressure and
suction pressure should be observed on this gauge.
A. If pressure does not build up rapidly to condens-
ing pressure when the Pilot Control is de-ener-
gized, proceed as follows:
1. Make certain that the electrical circuit has been
broken to the Pilot Control. Since the actuat-
ing device is generally at a remote point, we
suggest that a means for temporarily interrupt-
ing the current be made near the valve installa-
tion to facilitate servicing the equipment.
2. Check to see that no restriction exists and pres-
sure 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 con-
nection 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 avail-
able 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 thermostatic 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.
3-WAY HOT GAS DEFROST VALVES
Types 10G79B, 10G711B, 10G711C
Installation
CAUTION: The valve body must be wrapped with
a wet cloth while soldering to avoid damage to syn-
thetic internal parts. While the valve’s steel body
construction will help avoid overheating 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.
Service
Service parts for these valves may be ordered
through your local Sporlan wholesaler.
If a pilot assembly kit is required, note that they –
unlike the internal parts kits – are not interchange able.
For a list of replacement parts kits, see table, page 3.
