ESDV Emergency Shut Off Valve

Introduce Emergency Shutoff Valve Emergency shutoff valve have good technical performance, low load loss, and high reliability. Gas emergency shut off valve are used in conjunction with remote gas sources to control the opening and closing of the gas source control valve. In case of a large number of leaks or even a fire occurring in the pipeline or storage, one can rapidly manually relieve the pressure to unload the gas source.   Alternatively, when the high  temperature fusible alloy melts, the cylinder automatically depressurizes, the valve closes quickly, and stops the leakage, thus playing a role in ensuring the safety of the facility. Emergency Shutdown Valve Working Principle 1. When emergency shut down valve is closed, the spool is in full contact with the valve seat and has good sealing. At the same time, the compression spring below the spool exerts a closing force on the spool to keep the valve closed.   2. When the emergency shutoff valve needs to be opene…
