slow-start valve
Valve operation
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) in 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 - max 4 bar).
(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 without disconnecting system pressure at point 1.
