Product Introduction: Features of QDY421F-25/40 Liquid-Powered Emergency Cut-Off Valve:

This is a safety relief valve. Installed on the liquid and gas phase pipelines of LPG storage tanks, it is used in conjunction with a hand-cranked oil pump. It allows for quick depressurization of the hand-cranked oil pump cylinder in case of a large-scale leak or even a fire in the pipeline; or if high temperatures melt the fusible plug alloy, the valve cylinder will depressurize, causing the valve to close quickly and stop the leak, providing safety protection. This valve can be remotely controlled, closes rapidly, and opens flexibly.
