H3 & F7 Sandwich Regulator
ISSUED: December, 2000
Supersedes: July, 1999
Rev. 4, ECN# 9319
Introduction
Follow these instructions when installing, operating, or servicing the product.
Application Limits:
These products are intended for use in general purpose compressed
air systems only.
Operating Inlet Pressure: kPa psig bar
Maximum 1034 150 10.4
AmbientTemperature Range: 0°C to 52°C (32°F to 125°F)
Voltage Range: +10% to -15% of rating
(Applicable only for solenoid operated valves)
NOTE: Some of the above ratings are those of the associated valve.
Lubrication
Factory Pre-lubed.If lubricating in service, use Parker F442 oil or equivalent
paraffin based mineral oil with 150 to 200 SSU viscosity @100°F.
!
CAUTION:Do not use oils that are synthetic, reconstituted,
have an alcohol content or a detergent additive.
Wiring Instructions
Sandwich Regulators for electrically operated valves include a bridge
plug which directly connects the valve electrical plug with the subbase
or manifold plug.
!
CAUTION: An interruption of 10 milliseconds or greater to
the power supplied to the solenoid of a solenoid operated
valve may cause the valve to shift. Provision must be made
to prevent power interruption of this duration to avoid
unintended, potentially hazardous, consequences.
NOTE: Follow all requirements for local and national electrical codes.
Installation & Operating Instructions:
A sandwich regulator is used to provide regulated pressure to individual
valves in a manifolded valve arrangement. Three basic modes of
regulation are available as follows:
Common Port Regulation - Provides adjustable regulated air
pressure to the valve inlet.
Independent Port Regulation - Provides (2) separately adjustable
regulated air pressures to the outlet ports, one through each of
the valves exhaust passages.The valves exhaust (coming out of
its inlet passage) is directed to manifold or subbase exhaust port
“3”.
Single Port Regulation - Provides adjustable regulated air
pressure to one outlet port through the corresponding valve
exhaust passage and full inlet pressure to the other. The valves
exhaust (coming out of its inlet passage) is directed to manifold
or subbase exhaust port “3”.
!
CAUTION: With Independent Port and Single Port
Regulation the valves’flow functions are reversed as
indicated by the diagrams on page 2 of these
instructions. Wiring and plumbing must be adjusted
accordingly. Common Port Regulation does not affect
the valves function.
Sandwich regulator should be installed with reasonable accessibility
for service whenever possible – repair service kits are available. Keep
pipe or tubing lengths to a minimum with inside clean and free of dirt
and chips. Pipe joint compound should be used sparingly and applied
only to the male pipe — never into the female port. Do not use PTFE
tape to seal pipe joints – pieces have a tendency to break off and
lodge inside the unit, possibly causing malfunction.
Air applied to the sandwich regulator must be filtered to realize
maximum component life.
If used in conjunction with an H3 or F7 Sandwich Flow Control,
assemble between the valve and the Sandwich Flow Control.
H3 or F7 Valves: H3 or F7 Flow Control “Sandwiches” are only
recommended for use with Common Port versions of Sandwich
Regulators. If used with Single Port or Independent Port versions of
Sandwich Regulators, functionality is limited as follows:
Flow Control “Sandwich”used in conjunction with Single or Independent
Port versions of Sandwich Regulator - Adjust speed with the adjusting
screw labeled “3”. It adjusts the speed of exhaust flow from cylinder
ports “2” and “4”. Independent speed adjustment is not possible. This
could result in different exhaust speeds for cylinder ports “2” and “4”
since line pressure is supplied to one cylinder port and a regulated
pressure is supplied to the other. The other adjusting screw is non-
functional.

Installation
1. Remove the valve from the subbase or manifold (if assembled)
by removing and retaining the mounting screws.
2. Convert the valve to external pilot supply per the Conversion of
Valve to External Pilot Configuration procedure found below.
3. Clean all mating surfaces of valve, subbase or manifold and
sandwich regulator of dust and dirt.
4. Add a drop of low strength thread locking compound to male
threads of male-female tie rods and screw into subbase or
manifold and tighten 9.0 to 11.3 Nm (80 to 100 in-lb).
5. Slide gasket and Sandwich Regulator over male-female tie rods
protruding from top of subbase or manifold and press down on
Sandwich Regulator to seat electrical plug.
6. Place valve on top of Sandwich Regulator lining up all mounting
holes and press down on valve to seat electrical plug.
7. Assemble valve to sandwich regulator with valve mounting screws.
Tighten 9.0 to 11.3 Nm (80 to 100 in-lb).
8. Apply pressure to subbase or manifold and check for audible
leakage at joints.
9. Adjust outlet pressure per Outlet Pressure Adjustment procedure
at right to verify proper function.
Conversion OfValveTo External Pilot
Supply Configuration
!
CAUTION: H3 & F7 valves equipped with solenoid
operators or remote operated valves with air return must
be converted to external pilot supply in order to insure
proper valve operation.
Sandwich Regulator Model Numbers L95433*** and L95434*** will
provide inlet air from the subbase or manifold to external pilot supply
connection “12”in the valve.Model Numbers L95431*** and L95432***
require that pilot supply air 241 to 1034 kPa (35 to 150 PSIG) be
connected to pilot supply connection “12”in the subbase or manifold.

3. Position selector seal on valve body as shown below: The
cylindrical projection on the selector seal will block the internal
pilot supply located on the end of the valve body.
4. Reassemble solenoid end cap(s) (D) and air return end cap (F)
(where required).Tighten screws (C & E) 4.5 to 5.6 Nm (40 to 50

Conversion to external pilot supply is accomplished by inserting small
plugs in the sandwich plate located on the bottom of the valve.These
plugs are located in small holes which are identified as follows:
Place the plugs in the proper holes per the table below as follows:
To remove a plug, insert a narrow tool under the side of the nib and
pry it upward slightly. Then, grasp the projecting nib (long nose pliers
may help) and pull it out. Examine the o-ring to be sure it is not torn or
nicked, and that it has a coating of grease. Install the plug into the
appropriate hole (o-ring end enters first) by pushing it in place until it
comes to a stop and the nib is flush with the surface of the sandwich
block.

Blank = Pilot hole must be left open
M = Pilot holes may be molded shut and will not need a plug; however,
some holes may be open and therefore will require a plug. Use a
probe to test if the holes are open - the probe must be able to pass
through the thickness of the sandwich block for the holes to be open.

Outlet Pressure Adjustment
1. Before turning on the air supply, turn the adjusting knob
counterclockwise until compression is released from the pressure
control spring then turn on air supply. Proceed to adjust the
desired downstream pressure by turning adjusting knob clockwise.
This permits pressure to build up slowly in the downstream line.
2. To decrease regulated pressure setting, always reset from a
pressure lower than the final setting required. Example, lowering
the secondary pressure from 550 kPa (80 PSIG) to 410 kPa (60
PSIG) is best accomplished by dropping the secondary pressure
to 345 kPa (50 PSIG), then adjusting upward to 410 kPa (60
PSIG).
3. When desired secondary pressure setting has been reached,
push the adjusting knob down to lock the adjusting knob.
Regulator Spring Conversion
1. Shut off main and pilot air supplies and depressurize the unit.
2. Disengage the adjusting knob (A) by pulling outward. Turn
adjusting knob counterclockwise until the compression is released
from the pressure control spring (10).
3. Unscrew the collar (B) and remove the bonnet assembly (C).
Remove diaphragm assembly (1) and spring (10).
4. Replace spring (10) with one for new pressure range and
assemble along with diaphragm assembly (1) into bonnet
assembly (C).
5. Assemble bonnet assembly (C) and collar (B) to regulator body.
Tighten collar hand tight plus 1/4 turn.
6. Reapply pressure to unit and check for audible leakage at joints
or out bleed holes.
7. Adjust outlet pressure per Outlet Pressure Adjustment procedure
above to verify proper function.
