In the trunnion mounted ball valve design, the sealing rings are floating and the ball is fixed. The ball and the stem are attached to each other on both sides of the ball, which provides more support, especially as the ball size increases.

The fully welded construction of the trunnion mounted ball valves increases district heating lines’ lifetime as it eliminates the risk of leakage and air ingress. The face-to-face lengths of the valves are standardized, which guarantees space-saving installation of the valves. Valves can be installed in any position and have four lifting lugs, which makes the moving and turning of the valve easier even in locations where the space is limited.
