Highlight: Pneumatic trunnion ball valve
Product introduction:
Trunnion mounted fixed ball valve is a new generation of high-performance ball valve, suitable for long-distance pipelines and general industrial pipelines. Its strength, safety, and resistance to harsh environments have been specially considered in design, making it suitable for various corrosive and non corrosive media. Compared with floating ball valves, during operation, all the force generated by the fluid pressure in front of the valve on the ball is transmitted to the bearing, which will not cause the ball to move towards the valve seat. Therefore, the valve seat will not bear excessive pressure. Therefore, the torque of the fixed ball valve is small, the deformation of the valve seat is small, the sealing performance is stable, and the service life is long. It is suitable for high-pressure and large-diameter situations. Advanced spring pre-valve seat components with self tightening characteristics, achieving upstream sealing. Each valve has two seats that can be sealed in each direction, so there is no flow restriction during installation and it is bidirectional. This valve is generally installed horizontally.

Product features:
1. Frictionless opening and closing: This feature completely solves the problem of traditional valves affecting sealing due
to mutual friction between sealing surfaces.
2. Top-entry structure: Valves installed on pipelines can be directly inspected and maintained online, effectively reducing
equipment downtime and lowering costs.
3. Single seat design: Eliminates the safety hazard caused by abnormal pressure buildup in the valve cavity medium.
4. Low torque design: The specially structured valve stem allows the valve to be easily opened and closed with just a small
handwheel.
5. Wedge-shaped sealing structure: The valve relies on the mechanical force provided by the stem to press the ball
against the seat for sealing, ensuring that the sealing performance is not affected by changes in pipeline pressure
difference and remains reliable under various working conditions.
6. Self-cleaning structure for sealing surfaces: When the ball tilts away from the seat, the pipeline fluid passes uniformly
around the ball's sealing surface at 360°, not only eliminating local erosion of the seat by high-speed fluid but also washing
away deposits on the sealing surface to achieve self-cleaning.
