Pneumatic emergency shut-off valve (Pneumatic emergency shutdown - off valve) is a single acting piston type pneumatic straight travel shut-off valve, which is a protective safety device for oil depot, gas station, ammonia station storage tank and crane arm loading and unloading system, and an important measure to ensure safe production and personal safety.
Pneumatic emergency shut-off valve (Pneumatic emergency cut off valve) is equipped with a high-temperature automatic pressure relief closing device. The actuator is equipped with a soluble alloy plug. When the ambient temperature exceeds the set value (75 ± 5 ℃) of the soluble alloy at high temperature or in case of fire, the soluble alloy will be dissolved, the air source pressure will be relieved from the exhaust hole, and the shut-off valve will close quickly.
Pneumatic emergency shut-off valve (Pneumatic emergency shutdown valve) can also be equipped with electronic components (explosion-proof solenoid valve, signal feedback device), which are interlocked with the automatic control system or liquid ammonia/gas leakage alarm device to effectively ensure the stability and safety of the storage tank system against fire and leakage.
