Shutoff valves are designed to control the flow of gas and other substances with either full on and full off functionality. The shutoff gas valve could equip with our gas alarm detector, once there is alarm from our gas alarm detector, our detector could activate the valve to shut off the gas flow in the gas pipe to ensure the safety.

Airradio natural gas detector is for natural gas. If there is gas at home, once the concentration of the detected gas reaches the dangerous value, the detector will send out the audible and visual alarm signal, prompting you to take effective measures quickly to eliminate the danger and effective|y avoid the accidents such as fire and explosion.
