Encapsulated explosion-proof: no spark, more stable and reliable;
Valve opening mode: manual reset, avoiding accident;
Retaining mode: to work stably as the valve is open or closed (i.e. bi-stable state);
Speed to close: cut off gas supply within 1s;
Shutdown in case of violent shaking; the valve can shut down automatically in case of violent sharking;
Independent pressure release: in case of a big difference of pressure in front of and behind the valve, the valve can be opened after the pressure release valve is opened. Thus, fuel gas will not be released into the air, eliminating hidden safety troubles;
