CASH VALVE™ TYPE B-95 PRESSURE REDUCING OR PRESSURE BUILD REGULATOR
INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS
Refer to the Type B-95 regulator exploded view for 
parts identification.
Servicing Diaphragm(s) and Pressure Spring
1. Loosen the lock nut and turn the adjusting 
screw counterclockwise until the pressure 
spring is no longer under tension. When 
reassembling, run the adjusting screw down 
until the lock nut almost touches the spring 
chamber. This will give you approximately 
the same set as before disassembly.
2. Remove the assembly screws securing 
the spring chamber to the body. During 
reassembly, tighten the screws evenly in 
a star pattern. See chart below for torque 
values.
3. Remove the spring chamber. Then remove 
the spring button, pressure spring, and 
pressure plate.
4. Remove the diaphragm(s) and diaphragm 
gasket (a diaphragm gasket is only 
present when construction calls for metal 
diaphragms).
5. Remove the pusher post button. During 
reassembly, ensure the pusher post button 
is centered properly on the pusher post.
6. Inspect all parts for wear and damage and 
replace if necessary. Reassemble parts 
in reverse order. DO NOT OVERTIGHTEN. 
Follow the Operation Instructions to reset 
the delivery pressure.
CAUTION
Before attempting to replace any spare parts, be 
sure to shut off all pressure connections to the 
valve. With the valve closed, however, system 
pressure could still be locked between the 
shut-off valve and the inlet and/or outlet sides of 
the relief valve. Before proceeding with the valve 
service, be certain to relieve the pressure from 
BOTH sides of the valve
Servicing the Cylinder, Piston, Strainer 
Screen and Plug Gasket
1. Loosen the lock nut and turn the adjusting 
screw counterclockwise until the pressure 
spring is no longer under tension. When 
reassembling, run the adjusting screw down 
until the lock nut almost touches the spring 
chamber. This will give you approximately 
the same set as before disassembly.
2. Remove the bottom plug. Take care, as 
the bottom plug is under slight tension as 
a result of the piston spring acting against 
the bottom plug. Remove the piston, piston 
spring and strainer screen.
3. Thoroughly clean the strainer screen and 
remove any debris from the valve body.
4. Remove the hexagon cylinder.
5. Inspect all parts for wear and damage. If 
either the cylinder or piston need replacing, 
it is necessary to replace both as both parts 
wear equally.
6. Reassemble the valve in reverse order. DO 
NOT OVERTIGHTEN. Follow the Operation 
Instructions to reset the delivery pressure.

MAINTENANCE INSTRUCTIONS
The following procedures are provided for 
servicing the recommended spare parts for the 
Type B-95 regulator. Repair parts can easily be 
installed without removing the regulator from 
the line. 
OPERATION INSTRUCTIONS
Adjusting the Delivery Pressure
The regulator's delivery pressure setting is 
adjusted by turning the adjusting screw (1) 
at the top of the spring chamber (5) after 
loosening the adjusting screw lock nut (2). To 
increase delivery pressure, turn the adjusting 
screw clockwise (into the spring chamber). 
To decrease the delivery pressure, turn the 
adjusting screw counterclockwise (out of the 
spring chamber). After each adjustment, draw 
flow downstream and close to check new 
setting. Tighten the adjusting screw lock nut 
after the adjustment has been made.
