Kromschroder JSAV Overpressure Shut-off Valve

The Kromschroder JSAV is an overpressure shut-off valve used to protect against high pressure for valves downstream from a gas regulator. If downstream pressure exceeds the spring setpoint of the overpressure shut-off valve, the gas supply is automatically shut off.

The JSAV is suitable for natural gas, clean coke oven gas, LP gas, and biologically produced methane (max. 0.02%/v H2S). It must be paired with a VSBV safety relief valve to function properly. Its gas media must be dry and free of condensate in all temperature conditions.
