OSE Slam-Shut Valve

OSE Slam-Shut Valve The purpose of the Type OSE slam-shut device is to totally and rapidly cut the flow of gas when the inlet and/or outlet pressure in the system either exceeds or drops below setpoints. The Type OSE consist of a valve, either mechanism box, BM1 or BM2, and either one or two manometric sensing devices (BMS1 or BMS2).
