Vanaz R 4326 Slam Shut off Valve

Slam Shut off valve is installed immediately after the filter & prior to the regulator. It normally remains open, in case the outlet pressure of the regulator exceeds the permissible limits, the slam shut off valve senses it through the impulse line and immediately shuts off the flow to downstream. When the regulator is repaired, the slam shut off valve is to be open manually by pulling the knob. Once the flow starts through the slam shut off valve it will remain open till the outlet pressure of the regulator is within limits. Available in self sensing and external sensing.
