Emergency shut-off valve, also known as safety cut-off valve, means that in case of an emergency, the valve will be quickly closed or opened to avoid accidents.

Applications of Emergency shut-off valve:
1. It is connected with the combustible gas leakage monitoring instrument. When the instrument detects combustible gas leakage, it will automatically and quickly close the main gas supply valve, cut off the gas supply, and stop the occurrence of vicious accidents in time.
2. It is connected with the limit temperature (pressure) safety controller of thermal equipment. When the temperature (pressure) of the detection point in the equipment exceeds the set limit value, it will automatically and quickly close the gas supply valve and stop the fuel supply.
3. It is connected with the central fire alarm system of high-rise buildings. When a fire occurs in the building, it will automatically cut off the gas supply in the building to prevent the occurrence of gas explosion.
4. Install the ZCR gas emergency shut-off valve in the gas supply pipeline network of the city or factory, which can be centrally controlled in the central control room, and the pipeline gas supply at the accident site can be shut down by remote control in an emergency.

Emergency shut-off valve has excellent technical performance, low load loss and high reliability. It is suitable for combustible gases such as coal gas, natural gas and liquefied petroleum gas, and is widely used in the safety facilities of gas supply pipeline network systems, gas thermal energy factory workshops, gas boiler rooms and residential buildings. The gas emergency shut-off valve is a normally open pulse-triggered solenoid valve with emergency self-locking and manual reset functions.
