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. 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. WebTo enable modulation 2-Port control valves to operate with an acceptable authority, a DPCV is installed to limit the circuit pressure differential.
