Over pressure Shut-off valve is installed immediately after the filter & prior to the Regulator. It normally remains open, incase the outlet pressure of the regulator exceeds the permissible limits, the slam shut off valve senses it through the impulse line & immediately shut off the flow to downstream.

When the regulator is repaired, the slam shut off valve is to be opened manually by pulling the knob. Once the flow starts through the slam off valve it will remain open till the outlet pressure of the regulator is within limits.

We Are Able to Supply these valves for first stage as well as for second stage gas trains
