CASH VALVE™
A-360 AND A-361 PRESSURE REGULATORS
INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS
MAINTENANCE INSTRUCTIONS
The following procedures are provided for
servicing the recommended spare parts for the
Types A-360 and A-361 regulators. Repair parts
can easily be installed without removing the
regulator from the line.
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
regulator. Before proceeding with any valve
service be certain to relieve the pressure from
BOTH sides of the regulator.
Servicing Diaphragm(s), Top O-Ring, 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 spring chamber from the
body. When reassembling, torque to
50-60 ft-lbs (67.8-81.3 N•m).
