Pilot-operated solenoid valve block P31

2-way3/2-wayair

Product Overview
The P31 and P32 valves from Global FRL safely evacuate trapped air from pneumatic systems during fault or emergency-stop (E-stop) conditions. These valves are externally monitored and engineered for use in single-channel safety architectures up to Category 2, Performance Level c (PL c). Available actuation options include solenoid and air pilot versions to suit different machine designs and pressure requirements.
