Ball valve

2 piece flanged floating ball valve with ISO 5211 mounting pad

2 piece flanged floating ball valves feature a high quality investment cast body and end. They are available in 1/2” through 6” and are regular port. Superior leak protection is accomplished by using our patented “pyramidal” stem seal system shown in the graphic below. This advanced system protects against wear and leakage experienced by ordinary ball valves.Two-piece Body, Floating Ball,Buint-in ISO5211 direct mounting pad,Full silicasol technology Full bore,Blow out Proof Stem Fire safe des…

2 Piece Floating Ball Valve

2 Piece Floating Ball Valve is a valve with its ball floating (not fixed by a trunnion) inside the valve body, it drifts toward to the downstream side and tightly pushes against the seat under the medium pressure to ensure sealing reliability. The floating ball valve has simple structure, good sealing performance but the seat material is required to withstand the workload since the sealing pressure is bared by the seat ring. Due to unavailability of high performance seat material, floating ball v…

Casted Trunnion Mounted Ball Valve

Casted Trunnion Mounted Ball Valve are designed in accordance with API6D featuring 2 pc or 3 pc split body side entry or top entry design. Wide range of sealing material including PTFE, Peek, Devlon, Nylon etc, valve can be used in working temperature range -46℃~ 500℃. This series of valves are optional designed with Double block and bleed or double piston type. All valves are equipped with sealant injection system for both stem and seats to allow external intervention to prevent seat or stem l…

3 Piece Forged Trunnion Mounted Ball Valve

3 Piece Forged Trunnion Mounted Ball Valve are designed in accordance with API 6D for class 150,300,600,900,1500,3 piece forged steel side entry design bolted connections between body and closure, trunnion bolted connection,body thickness comply with ANSI B16.34. Seat ring is trunnion mounted type,spring loaded to assure the contact with ball in order to provide an effective tight seal even at low differential pressure between cavity and downstream closure. Standard design is soft seated, A diffe…

Segment V Port Ball Valve

V port Segment ball valve is a quarter-turn control valve. V port valve core is designed with a special V shape notch. Segment ball valve is one type of ball valves, its closure is a half ball with V port which has sharp edges. during operation the valve, friction action will be occurred between its closures that producing a strong shearing force to the medium, and a fan-shaped area will be formed between V port of the ball and the port of seat ring, so the section are of flow port can be changed…
