Cash Valve Type E-55 Pressure Regulator Installation guide
CASH VALVE TYPE E-55
PRESSURE REGULATOR INSTALLATION INSTRUCTIONS
Before installation, these instructions must be read carefully and understood.
DESCRIPTION
GENERAL INSTALLATION INSTRUCTIONS
OPERATING INSTRUCTIONS
The Type E-55 pressure reducing and
regulating valve automatically reduces a high
inlet pressure to a lower delivery pressure
and maintains the lower pressure within close
limits even during high flow rates.
Type E-55 regulators 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 and a pressure
gauge between the regulator and the
downstream 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.
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. Open a valve or faucet downstream to
draw flow and close to check the pressure
setting after each adjustment.
