Plug Valve

Main features: Plug is pressed into body cone surface tightly to form a good sealing area, and injects sealant into the sealing area to form a sealing film. Lubricated plug valve is a kind of bidirectional valve, which can be widely used in oilfield exploitation, transportation and refining plant, while also can be used in petrochemical, chemical, gas, LNG, heating and ventilation industries and etc.

Main features: Body seat is a sleeve with self lubrication well fixed by pressing into the body by high pressure to prevent leakage through the contact surface between body and sleeve. Sleeve plug valve is a kind of bidirectional valve, which can be widely used in oilfield exploitation, transportation and refining plant, while also can be used in petrochemical, chemical, gas, LNG, heating and ventilation industries and etc.

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.

Main features: The plug is divided in 3 pieces: 1 piece of plug, 2pieces of segments that connected together by dovetails. During opening process, rotates the stem anticlockwise and pulls the slips away from the body through dovetails and the wedging action between the plug and segments, 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.
