Slow Start Valve

The slow-start valve is a very compact and sensitive valve which is designed to apply pressure to a pneumatic circuit in two phases. (a) When the pilot solenoid valve (X) is energised a progressively increasing pressure is applied to the circuit over a period of time set by screw (S). The progressive start pressure is set by adjusting screw (R) (b). Once the set pressure (screw R) has been reached, the slow-start valve begins to automatically feed the circuit with the system pressure. When the solenoid is de-energised the system pressure is exhausted at point 1.
