Description
Use the JSAV to protect against high pressure for valves downstream from a gas regulator. The gas supply is shut off if the downstream pressure exceeds the spring setpoint of the over pressure shut-off valve. It is suitable for natural gas, clean coke oven gas, and LPG.
The VSBV is a safety relief valve that reduces temporary pressure surges caused by fluctuations in system operation downstream from the pressure reducing regulator. It is required for use with the Regulator JSAV Overpressure Shut-off Valve.
