Fixed Ball Valve

9 products found

A fixed ball valve (trunnion-mounted ball valve) is a quarter-turn rotary valve featuring top and bottom mechanical anchor points to support the spherical ball. Engineered for high-pressure, large-diameter piping systems, this configuration utilizes spring-preloaded floating seats that shift against the anchored ball under line pressure, minimizing operating torque and preventing seat deformation. These valves feature dual-sealing double block and bleed (DBB) capabilities, allowing the body cavity to be safely drained via a bleed valve while under full pipeline pressure. They incorporate an automatic self-relieving seat design that vents abnormal cavity overpressure back into the line, plus an emergency sealant injection system for secondary packing integrity. Pipeline design engineers and energy sector procurement managers can maximize high-pressure isolation safety and extend operational life by importing certified fixed ball valves directly from specialized manufacturers in China via our advanced B2B commercial platform.
