WebDPCV. To meet the growing use of variable speed pumps for HVAC applications, Hattersley has launched a range of Differential Pressure Control Valves (DPCV) specifically aimed at optimising system performance. Extremely efficient, the DPCV is set to a maximum differential pressure which ensures flow cannot exceed a desired rate. WebQ.02 What is the difference between a PICV and a PICCV? Some manufacturers claim their valve is pressure independent if it controls flow. A truly pressure independent valve controls flow and has a pressure independent control characteristic. The Hattersley PICV is fully pressure independent.

Differential Pressure Control Valve Working Principle

WebPressure and differential pressure relief controllers consist of a valve and a pressure actuator. Primarily used to limit a pressure (A) or differential pressure (PA) over a system/substation/pump. Controllers are normally closed: AV (P)A due to a normally closed valve and AF (P)A due to a stretching spring.
