High Flow Pneumatic Timer

This is a high-flow 5 way valve with a pneumatic timer which allows the automatic return of the valve after a preset time. The time is adjusted by screw (R). When a signal is applied to X the valve will stay operated until the time which was set at R has elapsed, and then the valve will automatically re-set. To repeat the cycle the signal must be exhausted and then applied again. If a momentary signal is applied the valve will operate as a conventional 5 way mono-stable valve without the time delay function. The valve will only operate when pressure signal is applied to X.
