Kromschroder JSAV Overpressure Shutoff 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 shutoff 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.
