WebOct 6, 2024 · When the Control Valve is closing, it will gradually overtake the pressure drop of other devices installed in the circuit. Only when the pressure drop of the circuit, including the Control Valve, is increased, the flow across the circuit will decrease. 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.
