A3031 Plug-In Fast Response Solenoid Pinch Valve
Ideal for Fuel Cell Applications Under Freezing Conditions

Compact and reliable, new technology solenoid valves provide rapid response for flow control of liquid or gas. From bubble-tight seal to full open in <10 msec! Rugged injection-molded thermoplastic housing allows operation in a variety of environments.

  • Flow Direction Either Way
    Operation is not directionally dependent

  • Shaft Seals not Required
    Flow stream is isolated from solenoid coil

  • Less Weight, Size & Cost
    Result from high performance solenoid & pinch valve design, using
    medical-grade silicone tube.
