Feature: 1. MAIN USE: The valve controller is mainly used in places where combustible gas (such as liquefied petroleum gas, natural gas, biogas, etc.) may leaks, to detect whether the gas leaks, and to ensure crowd safety. 2. SENSITIVE: The valve controller adopts semiconductor sensor, possesses premium stability and small sensitivity drift performance. 3. EASY TO INSTALL: No need to change the original configuration of the gas pipeline, which can be installed and put into use quickly. 4. AUTO, MANUAL: The valve controller supports 2 operating methods, auto and manual. In case of alarm, the main valve at home is automatically closed by the controller and the power supply is completely cut off. During power failure and maintenance, the valve can be opened manually to double the safety. 5. ABS MATERIAL: Made of premium ABS material, the controller has a insulated, flame retardant shell, ensures a long life span. 6. WIDE APPLICATION: The controller is widely used for automatic control of gas pipeline ball valve, gas cylinder ball valve, various connection alarms, other gas and liquid valves.
