Production Description:
Cast Steel Trunnion Mounted Ball Valves is a new generation of high-performance, suitable for long distance pipelines and general industrial pipelines, its strength, safety, resistance to harsh environments such as in the design for a special considerations applicable to a variety of corrosive and non-corrosive media. Compared with floating ball, work, force the fluid pressure in the valve before the ball is passed to generate all the bearings, does not make the ball move to the seat, so the seat will not put too much pressure, so fixed ball valve the torque is small, a small seat deformation, stable sealing performance. Suitable for high pressure, large diameter applications. Advanced pre-spring seat assembly, with self-tightening properties, to achieve the upstream seal. Each valve has two seats in each direction can be sealed, so installation does not restrict the flow is two-way.
Q47F \ H stainless steel ball valve has two fixed and three-two-type body structure, bolted flange seal with PTFE inserts into the stainless steel circle , steel springs ensure no rear seat close to the ball holding sealing. Up and down the stem are no PTFE bearings, reducing friction and effortless operation, the bottom of the small shaft no trim tab, ensure access at the position of the ball and seal . Full Bore: valve flow aperture is consistent with the inner diameter of the pipeline to pipeline cleaning.
Suitable medium: water, gas, oil, gas and acid corrosive media.
Temperature: -196 ~ 350
Driving modes: manual, pneumatic, electric, hydraulic, and so on.
DN: DN 25-800 1 "~ 32"
