Soft-start valve - 1/4 - 3/8", max. 15 bar | VAP 100
Two models of this 2/2 progressive valve are available, one that uses solenoid actuation and the other using a pneumatic version. It is an STD progressive start valve that is designed to open automatically as soon as downstream/upstream pressure ratio gets close to 50%. The upstream air moves downstream via regulation needle when there is no pilot and the valve enables full flow once it receives a signal coming from the pneumatic solenoid or the outside. It is not designed to relive the downstream circuit.
