Product Description

Urgent Cut Off Valve for flammable gas
 

Material	WCB, Stainless steel
Size	DN4 - DN50 (thread end) Dn25- DN450 (flange end)
Working type	Direct action/ Direct diaphragm / Pilot piston type
Sealing	Soft sealing

Application:
1, This valve can be coonected with flammable gas leakage detector. When device sensed leaking of flammable gas, the valve shall automatically and quickly cut off the supply main valve so as to stop leakage and prevent dangerous accidents.
2, This valve can be coonected with limiting temperature(pressure) secure device of heating equipment. At limiting temperature or pressure sensed by the device, this valve will automatically cut off gas supply.
3, This valve can be coonected with central fire protection alarming system in high buildings. When fire happens in the bulidling, this valve will cut off gas supply and prevent buliding from flammable gas explosion.
4, This valve can be installed at flammable gas supply pipeline network in cities or factories. It can be remotely controlled in central monitor room and urgently cut off gas supply at accident scene.
5, It can be installed at any flammable gas supply pipelines to cut off gas during system inspection and maintenance.
