MEDENUS Safety Shut-off Valve Type S 50

The safety shutoff valve Type S 50 controls a given gas pressure. It interrupts the gas flow at excess pressure or gas shortage automatically. It may be used as a single safety device or in connection with the gas pressure regulator R 50 as a pressure controlling unit.

Function:
The diaphragm of the safety shutoff valve is actuated via an impulse line from the outlet side. When excess pressure or gas shortage lifts or drops the SSV spindle the latch lever reacts and the closing spring presses the valve disc against the valve seat. Minimum and maximum release pressure are set by adjusting the respective setting screws.
