Differential Pressure Valves

250-01 Reverse Acting Differential Pressure Valve

250-01 Reverse Acting Differential Pressure Valve

CLA-VAL models 250GE-01/ NGE250-01 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.

40-111 Differential Pressure Control

40-111 Differential Pressure Control

CLA-VAL models 40GE-111 / NGE40-111 are hydraulically operated, pilot controlled,
modulating valves designed to maintain a constant differential pressure across a
pipe-work sub-circuit or temperature control valve to a pre-determined value
despite fluctuations in mains pressure and/or flow-rate.
