API floating sphere for ball valve

Hard seal fixed ball seat assembly is suitable for long distance pipelines and general industrial pipelines, its strength, safety, resistance to harsh environment, etc. in the design of special consideration, suitable for all kinds of corrosive and non-corrosive media hard seal fixed ball valve. Fixed ball valve compared with floating ball valve, when working, the fluid pressure in front of the valve on the ball generated by the force is transferred to the bearing, will not make the ball move to the seat, so the seat will not bear too much pressure. Advanced spring preseat assembly with self-tightening features for upstream sealing. Each valve has two seats, each direction can be sealed, so the installation has no flow limit, is bidirectional. Suitable for all kinds of pipelines of Class150 ~ Class2500, PN16 ~ PN420, used to cut off or connect the medium in the pipeline. The hard seal fixed ball seat assembly is suitable for non-corrosive medium, weakly corrosive medium, nitric acid, acetic acid, oxidizing medium, urea and other media, especially for containing solid particle medium, slurry, pulverized coal, ash and other harsh conditions. Hard seal fixed ball seat assembly collocation drive mode is manual, worm gear drive, pneumatic or electric. The two seats fixing the ball seat assembly can independently cut off the medium at the inlet end and the outlet end to achieve double blocking function. When the ball valve is closed, even if the inlet and outlet of the valve at both ends of the pressure, the valve cavity and both ends of the channel can be blocked each other, the remaining medium in the cavity can be discharged through the release valve.
