Soft Seated Trunnion Ball Valves
The Oil States Piper Valve Soft Seated Trunnion Ball Valves are a high performance ball valve design for a valve family consisting of a “body group” and an end connection kit. The valve design utilizes internal trunnion blocks which hold the ball rigid in the cavity. Upstream pressure, along with spring load, forces the upstream seat into the ball forming a seal.
