Plug valve

Plug valve is an auxiliary valve used in opening and throttling of high pressurized systems. It is used as by-pass to the line valve; it balances the pressure and provides the safe opening of line valve.

Plug valves have a conical or cylindrical obturator rotating around the axis perpendicular to the flow direction.

Plug valves for high pressure and/or high temperature services. It is important to make the material selection according to the fluid corrosion.

Valve body and stem can finish emergency injection seal, through the grease injection valve, the stop leak com pound can achieve short-time seal, theref or to buy time handling the scene.

Full teflon PTFE lined plug valve can be used in the whole pressure range to avoid leakage and shut off more convenient to the line system and pipeline maintenance.
