-300F to 450F -184C to 232C O-Ring dependent. Combination of SPE and DPE A trunnion mounted ball valve with the upstream seat unidirectional and the downstream seat bi-directional blocks the fluid at the downstream seat in both directions while it blocks the fluid on the upstream seat in one direction only. The ball is free to rotate resulting in even wear and a wiping action between the ball and seat. In the closed position ball is pushed against the seat by the pressure of the fluid from upstream and hence can pressure seal the downstream of. Ball valve design in which the ball is not rigidly held on its rotational axis is free to float between the seat rings.
