general information about floating & Trunnion Mounted Ball Valve
floating ball valve

A floating ball valve is a valve with its ball floating (not fixed by a trunnion) inside the valve body, it drifts toward to the downstream side and tightly pushes against the seat under the medium pressure to ensure sealing reliability.

trunnion mounted ball valves
In trunnion mounted valves, the ball is held in a fixed axial position by upper and lower stems (trunnions) and can move only in a rotational mode. the resilient seats are contained in metal carriers which are spring loaded against the ball. Line pressure applied to a close valve increases the spring load on the upstream seat to effect a tight seal. The primary seating is therefore on the upstream seat permitting trunnion mounted ball valves to be used for "block and bleed" service.
