An emergency shut-off valve for ammonia is a new type of valve product developed by absorbing the advantages of many other valves. It combines the advantages of globe valves, check valves, solenoid valves, and pneumatic valves, and has the characteristics of simple structure, sensitive response, and reliable action. Installed on liquid ammonia, gas or gas pipelines, used in conjunction with a gas source [nitrogen/anhydrous air],

By using a gas source to control the opening and closing of valves, in case of leakage or even fire on pipelines or storage tanks, workers can quickly relieve the pressure of the gas source through a remote solenoid valve or manually, or melt the gas source when the high temperature is ≥ 80 ℃ (molten alloy), and the cylinder will automatically relieve the pressure. The valve will quickly close to prevent leakage and provide safety protection.
