Slam-Shut Valve

Type OSE slam-shut valve is used to totally and rapidly cut the gas flow when the pipeline pressure exceeds the set pressure or when the pipeline pressure drops below the set pressure.

Type OSE consists of a valve, a water-tight mechanism box, and a manometric device. A double stage mechanism detects any pressure variances. Detection is the first stage and the mechanism will only trip when the pipeline pressure reaches the set pressure. The second stage is the power stage; once tripped, the closing spring causes the valve plug to slam shut and remain closed until the valve is manually reset.
