Features Trunnion ball valve is constructed

Trunnion ball valve stem through the flat keys or splines or square convergence deed with the handle, versatile,Trunnion ball valve convenient disassembly. Stainless steel ball valve stem with anti-blown construction. High-pressure valve packing selection knitting, flexible graphite seals or tetrafluoroethylene-ene ring, so that to achieve robust stainless steel ball valve stem seals must be smooth in the case. Based on need, high-pressure valve can be planned into the anti-static structure, providing a conductive spring between the ball and the Double ferrule fitting stem and the valve, to prevent static sparking extinguish flammable materials to ensure system safety. Trunnion ball valve seal vice situation varied. Trunnion ball valve task truth is by reversing valve love to make valve dredge or occlusion. Valve switch light, small size, can be made very large caliber, reliable sealing, simple structure, convenient maintenance,(Instrument needle valve) regular spherical surface and seal in the closed condition, can not easily be eroded media, in all sectors lost universal use.
