Description

The Cla-Val Model 60-11/660-11 is a pilot-operated booster pump control valve. It is installed on the discharge booster pump used to get rid of pipeline surges due to starting and stopping of the pump. Other features of this valve include a solenoid control that can be manually operated, and a built-in check valve. 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. Install the valve as shown to help prevent pipelines surges during pump starting and stopping. Flexible conduit should be used for electrical connections to the solenoid control and the limit switch. A Cla-Val Model 52-03 Surge Anticipator Valve is recommended for power failure protection or the Model 652-03 if a reduced port valve is required. Use the PC-22D Electronic Pump Control Panel for applications where electronic contol and integration with SCADA is desired. Note: Installation with valve stem vertical up is recommended. For horizontal stem installation use Cla-Val Model 60-73 or, if a reduced port valve is required, Model 660-73.
