Tank Liquid Ammonia Emergency Shut-off Valve Type Selection/Liquid Ammonia Valve

2018-12-27

Tank liquid ammonia emergency shut-off valve is normally open and normally closed two, different internal structure of different uses, should pay attention to the choice of purchase, to ensure safe production. Cutout Valve (Cutout Valve), also known as emergency shut-off valve, type: normally closed, normally open. Category: Pneumatic type, electromagnetic type, manual pneumatic type. 

1, normally closed liquid ammonia emergency shut-off valve; gas leak alarm alarm power, solenoid valve power exhaust, the valve automatically shut down. Normally closed shut-off valve uses gas (compressed air, nitrogen) and solenoid valve to control the valve on-off, widely used in gas, ammonia or weak corrosive gas storage tank inlet and outlet and pipeline. Used with long-distance air source, the air-source control valve is used to open and close so that when a large amount of leakage occurs in a pipe or a storage tank, the air source is quickly and manually decompressed or the fusible alloy melts at a high temperature of ≧ 75 ° C while the cylinder Automatic pressure relief, the valve quickly closed and only leakage, play a personal safety and protection.

 2, normally open liquid ammonia emergency shut-off valve; gas leak alarm alarm power, solenoid valve energized air pressure off the valve. Turn off the solenoid valve exhaust, the valve to open again. Normally open shut-off valve with excellent technical performance, low load loss and high reliability, installed in liquefied gas, natural gas, ammonia and gas pipeline, and long-distance air supply (compressed air, nitrogen) supporting the use of Air control valve is closed so that when an accident occurs in the pipe or tank, the staff quickly actuates the switch through the control room. The solenoid valve instantly energizes and the air source rapidly passes through the valve.
