Fire Safe Soft Seated Ball Valve , ISO 5211 Anti Static API 6D Ball Valve
Top Entry Ball Valve
Top entry trunnion ball valves trunnion mounted design, soft seated. The ball, seat rings and other trims shall be inserted into the valve cavity from the top first. Then, the bonnet, with the stem in place, is bolted to the valve body. Gaskets are employed to prevent leakage at the body-bonnet joint. A top entry trunnion ball valve can be conveniently maintained by removing the bonnet, without removing the valve from the pipeline. Compared to the split body side entry ball valves, it eliminates the possible leakage from body joints.
Design features and material selection
Top entry ball valves uses trunnion-mounted balls and spring-loaded seats, the ball has either integral or separate lower post that is seated in the bottom of the body. The seats are placed on both sides of the ball and the entire assembly is placed in the body. The top-works, consisting of a bonnet cap, packing box, gland flange, and separate stem, are installed above the ball. When the bonnet-cap bolting is tightened, the resulting compression energizes the seats. The joint between the bonnet cap and the body is sealed using gaskets.
