Product introduction:


The trunnion ball valve is a new generation of high-performance ball valves suitable for long-distance transmission pipelines

and general industrial pipelines. Its strength, safety, and resistance to harsh environments have been specially considered in

the design, making it suitable for various corrosive and non-corrosive media. Compared with floating ball valves, when in

operation, the force generated by the fluid pressure in front of the valve on the ball is entirely transmitted to the bearings,

preventing the ball from moving toward the valve seat. As a result, the valve seat does not bear excessive pressure, so the

trunnion ball valve features low torque, minimal valve seat deformation, stable sealing performance, and a long service life,

making it suitable for high-pressure and large-diameter applications. The advanced spring-loaded pre-valve seat assembly

has a self-tightening feature to achieve upstream sealing. Each valve is equipped with two valve seats, which can seal in

both directions, so there are no flow direction restrictions during installation, making it bi-directional.

Product features:


1. Frictionless opening and closing:This feature completely solves the problem of traditional valves affecting sealing due to

friction between sealing surfaces.

2. Top-entry structure:Valves installed on pipelines can be directly inspected and maintained online, effectively reducing

equipment downtime and costs.

3. Single seat design: Eliminates safety hazards 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 achieves sealing by using the mechanical force from the valve stem to press

the ball against the seat, 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-velocity fluid but also

washing away deposits on the sealing surface to achieve self-cleaning.
