SY5100-X31, Pilot Air Control Valve with Spool Detection and Spring Return Spool

Description

The SY5100-X31 is a single solenoid valve for controlling the pilot air supply to the dwonstream valves within its zone.  De-energizing the SY-X31 renders the downstream valves inoperable in response to a safe fault or for maintenance purposes.  The return spring assures the return of the valve to the safe state when de-energized without requiring pilot pressure.  The built-in switch provides an ON signal when the valve is de-energized in its safe state and an OFF signal when the valve is energized.  The 5000 series was used as it can be added to a 7000 series manifold or have 3000 series valves added to a 5000 manifold. - Reliably returns to safe state in case of power loss - Validated per ISO13849-2 to basic and well-tried safety principles - Main valve position when valve is OFF: Signal output - Main valve position when valve is ON: No signal output - Internal and external pilot models available - Available with M8-3 pin, M8-4 pin and M12-4 pin connector for switch - Available with low wattage coil for continuous duty
