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 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 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…
