Emergency shut-off valve: An emergency shut-off valve is a valve that can be quickly closed manually or automatically in an emergency. Cut off the gas supply quickly to prevent further accidents. Emergency shut-off valves can be hydraulic, pneumatic, electric, or manual, and emergency shut-off valves should be installed in the liquid and gas lines of storage tanks. Emergency shutoff valves must pass pressure and tightness tests. The closing time of the emergency shutoff valve should be within 5 seconds for valve diameter DN50 or less, and within 10 seconds for valve diameter over DN65.
