The operation of the pneumatic trunnion ball valve relies on pneumatic transmission. When compressed air enters the pneumatic actuator, it drives the internal piston or diaphragm to produce displacement, which in turn drives the valve stem to rotate. The valve stem is connected to the ball, and the

Understanding Trunnion-Mounted Ball ValvesDesign and FunctionTrunnion-mounted ball valves are designed to handle high pressures and large flow rates, making them suitable for critical industrial applications. The key design feature is the trunnion or ear-axis mechanism, which supports the ball and r

Understanding API 6D StandardsWhat is API 6D?API 6D, formally known as the Specification for Pipeline Valves, is a comprehensive standard developed by the American Petroleum Institute. It outlines the design, manufacturing, testing, and documentation requirements for ball valves and other types of v

Understanding Floating Ball ValvesWhat are Floating Ball Valves?Floating ball valves are a type of ball valve where the ball is not rigidly fixed but is allowed to float within the valve body. This design allows the ball to move slightly under the pressure of the fluid, ensuring a tight seal against
