Pressure Relief Valve

A pretensioned spring can be used to vary the switching pressure by approximately +/- 100 mbar. The switching time can vary by more than +/- 50 mbar and has hysteresis. An exhaust hose can be attached to the KF connection at the outlet side.

• To relieve overpressure
• KF on both sides
• Switching pressure approximately 200 mbar for DN 40, 400 mbar for DN 16
• Maximum opening approximately 55 mm² for DN 40, 10 mm² for DN 16
• Leakage rate: <1 x 10^-7 mbar l/s at 1 bar differential pressure
• Pressure range: 1 x 10^-6 mbar to 1.6 bar (abs.)
• Temperature range: 5 to 60 °C
• Valve seal: FPM (fluororubber)
• Not suitable for safety-relevant applications
