CASH VALVE™ A-360 AND A-361 PRESSURE REGULATORS
INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS
Servicing the Seat Disk and Bottom O-Ring
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 subassembly, piston spring, and
bottom o-ring. Lubricate bottom o-ring with
Dow Corning Molykote 111 or equivalent
before installing. Unscrew the pusher
post from the piston to remove the seat
disk. Do not lubricate the seat disk. When
reassembling, ensure that the pusher post
is seated completely against the seat disk;
torque the bottom plug to approximately
10 ft-lbs (13.6 N•m).
3. Remove any debris from the valve body.
