CLA-VAL 250-01 : Reverse Acting Differential Pressure Valve
Cla-Val Models 250GE-01 / NGE250-01 Reverse Acting Differential Pressure Valves are hydraulically operated, pilot controlled, modulating valve designed to be fitted on a typical by-pass and maintain a pre-determined pressure differential allowing “unwanted” water to “spill” from the flow pipe to return pipe. The valve tends to open on an increase in differential pressure and close on a decrease in differential pressure.
