The main applications are as follows:
Connected to the combustible gas leakage monitoring instrument. When the instrument detects a gas leak, it will automatically and quickly close the main gas supply valve, cutting off the gas supply and promptly preventing the occurrence of a serious accident.
When the instrument detects a gas leak, it will automatically and quickly close the main gas supply valve, cutting off the gas supply and promptly preventing the occurrence of a serious accident.
Connected to the safety controller for the maximum temperature (or pressure) of the thermal equipment.Connected to the safety controller for the maximum temperature (or pressure) of the thermal equipment. When the temperature or pressure at the detection point within the equipment exceeds the set limit values, the gas supply valve will automatically and quickly close, stopping the supply of fuel.
When the temperature or pressure at the detection point within the equipment exceeds the set limit values, the gas supply valve will automatically and quickly close, stopping the supply of fuel.

Product Application of Gas Emergency Shut-off Valve
The gas emergency shut-off valve is a new type of safety accessory for gas pipeline projects. Its main applications are as follows:
Connected to the combustible gas leakage detection instrument. When the instrument detects a gas leak, it will automatically and quickly close the main gas supply valve, cutting off the gas supply and promptly preventing the occurrence of a serious accident.
2. Connected to the safety controller for the maximum temperature (or pressure) of the thermal equipment. When the detected temperature or pressure within the equipment exceeds the set limit value, the gas supply valve will automatically and rapidly close, stopping the supply of fuel.
3. Connected to the central fire alarm system of the high-rise building. In case of an emergency in the building, the gas supply within the building will be automatically cut off to prevent the occurrence of a gas explosion.
4. Install ZCR gas emergency shut-off valves within the gas supply networks of cities or factories. Central control is implemented in the control room, with remote remote control capabilities. In case of an emergency, these valves can be remotely shut off to cut off the gas supply to the accident site.
