Our gas emergency shut-off solenoid valve is the gas pipe safety emergency shut-off device, which could be connected with home gas leak detection system, firefighting system and other intelligent alarm system to cut off gases supply when gas accident occurred. The valve shall be closed automatically when the harmful strong vibration is happened. The valve only can be opened again by manually that confirms to safety management regulation.

The valve uses interaction of instantaneous electromagnetic force, permanent magnetic and spring to open and close valve, mover, it will keep open and close.
Principle of close valve: the instantaneous DC pulse drive off valve
(DC9V/1S)
Example: Drive circuit principle diagram of capacitor discharge mode
A: Providing an instantaneous (about 1 second) DC pulse (D C 9 V ~1 2 V) power to electromagnetic coil.
B: Open the protection cover; pressure the red handle can also close the valve.
Caution: Under normal circumstances users should not open the dust cap, to avoid disoperation.
Caution: If it is difficult to pull up the red handle, please keep the pressure of valve import and export keep balance. Brutal operation can destroy it.

l Cable: use two-wired terminal crimping method. (2 x 0.5mm²)
l Control distance: capacitor discharge driving way: the length of wire is less than 30 meter.
Users should check valve’s opening and closing regularly, if users found fault, please ask professional or manufacture to maintenance.
