Application:
Capable of reliably closing and opening under high backpressure (high outlet pressure).
Split/splitless solenoid valves at the inlet of gas chromatographs (where backpressure can be high).
Bypass isolation valves for backpressure regulators at reactor outlets.
Process gas lines that require opening under high backpressure to prevent “failure to open” scenarios.
