Proven Reliable Design
The Cla-Val Model 60-73 Booster Pump Control Valve is a pilot-
operated valve designed for installation on the discharge of booster
pumps to eliminate pipeline surges caused by the starting and
stopping of the pump.
The pump starts against a closed valve. When the pump is started,
the solenoid control is energized and the valve begins to open slowly,
gradually increasing line pressure to full pumping head. When the
pump is signaled to shut-off, the solenoid control is de-energized and
the valve begins to close slowly, gradually reducing flow while the
pump continues to run. When the valve is closed, a limit switch
assembly, which serves as an electrical interlock between the valve
and the pump, releases the pump starter and the pump stops.
Should a power failure occur, a built-in lift-type check valve closes
the moment flow stops, preventing reverse flow regardless of
solenoid or diaphragm assembly position.

Typical Installation
Install Model 60-73 valve as shown. Flexible conduit should be used for
electrical connections to the solenoid control and the limit switch. The
Model 52-02 or 652-03 Surge Anticipator Valve is recommended for
power failure protection.
Note:
Valve stem can be located in either vertical up or horizontal position.
