kulventilutföranden

A kulventilutföranden, or ball valve design, refers to the various configurations and types of ball valves available for different applications. Ball valves are quarter-turn valves that use a hollow, perforated, and pivoting ball to control flow. The design of the ball valve housing, port, and seating mechanism determines its suitability for specific fluid types, pressures, and operational requirements.

Common kulventilutföranden include the full bore valve, which has a port diameter equal to the pipe's inner diameter, allowing for unobstructed flow and minimal pressure drop. Reduced bore valves have a port smaller than the pipe diameter, which can offer better control for certain applications but results in higher pressure loss. Trunnion mounted ball valves are designed for high-pressure applications, featuring a support structure that stabilizes the ball, reducing torque and preventing sagging. Floating ball valves, on the other hand, have a ball that is not fixed and is held in place by the seat.

Further variations exist based on connection types, such as flanged, threaded, or welded ends, which dictate how the valve is integrated into a piping system. Materials of construction for the valve body, ball, and seats are also critical design considerations, chosen based on the fluid's corrosiveness, temperature, and purity requirements. Specialized designs may incorporate features like locking mechanisms, actuator interfaces, or specific sealing materials to meet demanding industrial needs.
