Lift Plug Valve
- 双恒
- China
Main features: During opening process, rotates the stem anticlockwise and lift tapered plug moving up and pull the plug sealing surface away from the body seat, the clearance between the body and seals allows free movement without friction. Rotates stem further, with the tilt guide mechanism design, the plug will be turned 90°aligning plug port window to valve body bore that valve is fully opened. Because without abrasion between sealing surfaces, so the operating torque is very low and service life is longer. Twin seal plug valves are mainly used in CAA fuel storage plant, harbor refined oil storage plant, manifold plant, etc.
