The Operation Theory of Cast Steel Trunnion Ball Valve
The operation theory of the Cast Steel Trunnion Ball Valve involves a hollow ball with a trunnion-mounted design, controlled by the handle. When the handle is turned, the ball rotates within the valve body, either allowing or blocking the flow of fluid. This design, embraced by SKG Pneumatics Inc and acknowledged by Cameron Orbit Valve, ensures precise control over flow rates and direction, making it ideal for various industrial applications.
