Cash Valve Type G-60 1-1/4” & 1-1/2” Water/Air/Oil/Gas Pressure Regulator Installation guide
CASH TYPE G-60 1¼” AND 1½”
PRESSURE REGULATOR INSTALLATION INSTRUCTIONS
Before installation, these instructions must be carefully read and understood.
DESCRIPTION
GENERAL INSTALLATION INSTRUCTIONS
OPERATING INSTRUCTIONS
The Type G-60 high capacity, all purpose
pressure reducing and regulating valve
automatically reduces a high inlet pressure to
a lower delivery pressure and maintains the
lower pressure within reasonably close limits.
The Type G-60 regulator should be installed in
the horizontal position with the spring chamber
upright. For other installation requirements
consult the factory. For ease of operation and
maintenance, it is suggested that manual
shut-off valves be installed upstream and
downstream from the valve. Before installing
the valve, the piping and valve should be
thoroughly flushed out to remove any foreign
material. Install the valve with the inlet
pipe fitted to the inlet connection identified
on the valve body. On valves with threaded
connections, use a good pipe joint compound on
the male pipe threads and do not over tighten
the valve connections.
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 (3) after
loosening the adjusting screw lock nut (2).
To increase the delivery pressure, turn the
adjusting screw clockwise (into the spring
chamber). To decrease the delivery pressure,
turn the adjusting screw counter-clockwise (out
of the spring chamber). Tighten the adjusting
screw lock nut after the adjustment has been
made.

MAINTENANCE INSTRUCTIONS
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 or the
regulator. Before proceeding with any valve
service, be certain to relieve the pressure from
both sides of the regulator.
Refer to section view for parts identification.
Repair parts can easily be installed without
removing the regulator from the line.
