Overview

Floating Ball Valves

A Floating Ball Valve is a valve with seat supported ball that is pushed by upstream pressure towards the downstream seat to ensure sealing. The DN of the floating ball valves range is limited by the capability of seat’s material to support the pressure, temperature and weight of the ball.

Trunnion Ball Valves

A Trunnion Ball Valve is a form of quarter-turn valve which uses a hollow, perforated and fixed/supported ball to control flow through it. A trunnion mounted valve means that the ball is constrained by bearing and only allowed to rotate. Advantages of trunnion ball design are the lower operating torque, ease of operation, minimized seat wear. Superior sealing performance at both high and low pressure. The trunnion is available for all size and for all pressure classes but they are not suitable for throttling purposes.
