Side Entry Trunnion Ball Valve

Product Details

D’s standard side entry trunnion ball valves are designed to API’s highest standards. The 3-piece design offers maximum protection against line pressure and thermal distortion with long life and trouble-free performance. And supply its products to the Crude Oil Transport and Processing, Power Engineering, Water Supply Systems, and Process Industries.

Trunnion mounted stems absorb the thrust from line pressure, preventing excess friction between the ball and seats, so even at full rated working pressure, operating torque stays low.

3D ball valves have been fire tested and can be supplied to API 607. The soft seat inserts, irrespective of their materials, will possibly fail when subjected to sudden high-temperature conditions. We provide a fire-safe design that may substantially prevent leakages through seals when damaged by high temperature.

The seats are of both-side-sealing type, which means that they seal both on the upstream or downstream side of the ball valve and inside the valve. Whether in the open or closed position, pressure on each side of the ball is blocked from the body cavity by the seat rings engineered to self relieve it. No pressure build-up can occur into the body drained through the body port
