The trunnion ball valve represents a new generation of high-performance ball valves. It is designed for long-distance pipelines and general industrial applications, with careful consideration of strength, safety, and resistance to harsh environments. This valve is compatible with a wide range of corrosive and non-corrosive media. Unlike floating ball valves, when the trunnion ball valve is in operation, the force exerted by fluid pressure on the ball is entirely transferred to the bearings, preventing the ball from moving toward the valve seat and avoiding excessive pressure on the seat. As a result, trunnion ball valves feature low operating torque, minimal seat deformation, stable sealing performance, and extended service life, making them ideal for high-pressure and large-diameter applications. Equipped with an advanced spring-loaded seat assembly with self-tightening characteristics, the valve ensures effective upstream sealing. Each valve is equipped with two seats capable of sealing in both directions, allowing unrestricted bidirectional flow during installation. This valve is typically installed in a horizontal position.
