Hattersley introduces DPCVs

DPCV

Hattersley now offers differential-pressure control valves (DPCVs) for HVAC systems that rely on variable-speed pumps. These valves can operate at temperatures from -10 to 100°C in sizes from DN15 to DN50 and are PN16 rated. They can be set on installation to a maximum differential pressure from 20 to 100 kPa. Under dynamic balancing conditions they can be adjusted during commissioning as required to maintain the authority of the 2-port control valve.

DPCVs keep a system in balance regardless of changes in other areas of the circuit.
