Typical Application
Install Model 60-32/660-32 valve as shown in multiple pump
applications. Flexible water-tight conduit should be used for
electrical connections to the solenoid control and the limit
switch. A Model 52-03/652-03 Surge Anticipator Valve is
recommended for power failure protection.

The Cla-Val Model 60-32/660-32 Combination Pump Control and
Back Pressure Valve is a pilot-operated control valve designed for
booster pump discharge installation to eliminate pipeline surges
caused by starting and stopping of pump and to provide
adjustable back pressure on pump while it is running. The valve
features a modified globe-design with diaphragm-actuation, and
hydraulic operation for smooth, reliable automatic operation dur-
ing pump starting and stopping. A built-in lift-type check feature
automatically closes valve on electric power failure or any time
pressure reversal occurs to protect pump from back spinning.
In operation, when pump is off, the pump control valve is closed
by downstream system pressure. When pump is started, the
solenoid control is energized and valve opens slowly to gradually
increase pump flow and line pressure to desired back pressure
setting for pumping conditions. When pump is signaled to shut-
off, the solenoid control is de-energized and the valve begins to
slowly close, gradually reducing flow while pump continues to run.
When valve is closed, the included limit switch assembly turns off
pump. Adjustable flow controls are included to easily regulate
valve opening and closing speed to prevent surges.
Using Cla-Val wiring diagram (see page 4) ensures safe electrical
interlock control of pump and valve.
