H2, F6 and 4510 Sandwich Regulator
V-476BP
Installation
H2, F6 & 4510C Series Valves:
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 finger tight.
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 5.1 to 5.6 Nm (45 to 50 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.
4510A and 4510B Series Valves:
1. Remove the valve from the subbase or manifold (if assembled)
by removing and discard the (4) mounting screws.
2. Clean all mating surfaces of valve, subbase or manifold and
sandwich regulator of dust and dirt.
3. Place gasket on top of subbase or manifold. Select the proper
gasket per the following chart:

6. Place valve on top of Sandwich Regulator lining up all mounting
holes and press down on valve to seat electrical plug.
7. Attach valve and sandwich regulator to base with long mounting
screws (contained in kit). Tighten 13.0 to 14.7 Nm (115 to
130 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.
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.
Conversion Of Valve To External Pilot
Supply Configuration (H2 & F6 Valves Only)
!
CAUTION: H2 & F6 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 L95423*** and L95424*** will
provide inlet air from the subbase or manifold to external pilot supply
connection “12” in the valve. Model Numbers L95421*** and L95422***
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.
H2 Valves (Engineering Level ‘A’)
1. #14 End - Remove nut (A) solenoid coil (B), adapter block screws
(C) and adapter block (D).
2. #12 End - Double Solenoid Operated Valves - Remove nut (A)
solenoid coil (B), adapter block screws (C) and adapter
block (D).
#12 End - Single Solenoid Operated Valves - Remove screws
(E) and air return end cap (F).
3. Position selector seal on solenoid adapter(s) and air return end
cap (where required) 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
in-lb.) torque.
5. Reassemble solenoid coil (B) and nut (A) and tighten 3.4 to 4.5
Nm (30 to 40 in-lb.) torque.
H2 Valves (Engineering Level ‘B’) & F6 Valves
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 Table 1 on page 4.
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
