The valve is intended for prevention of LPG (propane, butane GOST 20448-90, GOST 27578-87) flow out of the full vessel in case of the hose/pipe break. The valve is used for protection of the environment from uncontrolled LPG leakages from the reservoirs and pipelines.

Two types of the valve are manufactured: KS (fast shut-off valve) and KSM (fast shut-off valve interflanged version).

KS valve has 2 manufacturing modifications: with nominal inside diameter of 15 or 40 mm.
