Feature:1. Small Sensitivity Drift: The gas pipe valve controller alarm kit uses semiconductor sensors with high stability and small sensitivity drift.2. Electric and Manual Conversion Clutch: The gas pipe valve controller alarm kit adopts electric and manual conversion clutch, which can automatically and push button electric switch and open the valve manually in case of power failure or maintenance.3. DC or AC 12V Safety Voltage: Automatically close the main inlet valve and completely cut off the power when alarming, using DC or AC 12V safety voltage, anti radio interference.4. Flame Retardant Shell: Easy to install, also adopts insulated and sealed flame retardant shell, no need to change the original configuration of gas pipeline, can be installed by itself.5. Use Scenario: The gas pipe valve controller alarm kit is mainly used in places where gas leaks may occur (such as liquefied petroleum gas, natural gas, biogas, etc.). Widely used in gas pipeline ball valves, gas cylinder ball valves, all kinds of connection alarms, etc.Specification:Electric Valve ControllerMaterial: ABS, brassUse: Widely used in gas pipeline ball valve, gas cylinder ball valve, all kinds of connection alarm, other gas and liquid valve automatic controlBasic Parameters.Working Environment: -20 - +60Rated Voltage: DC12V Working Voltage: DC8V-16VRated Current: 100mA Operating Current: 20mA-300mARated Power: 1.2W Working Power: 0.24W-3.6WValve Pressure: 1.5MPaAutomatic Valve Closing Time: 6-20 secondsElectric Open Valve Time: 6-20 secondsGas Leakage Detection AlarmMaterial: ABSBattery: 9V 6F22 x 1 (Shipping without battery)Use: Applied to the possible occurrence of gas (such as liquefied petroleum gas, natural gas, biogas, etc.) leakage placesBasic Parameters.Measuring range: 3000PPM (1500PPM).Package List:1 x Controller1 x Detector2 x Expansion Screw2 x Screw2 x Instruction Manual1 x Pipe Clasp
