TOP ENTRY BALL VALVES
 
When you need to decrease down time of critical service pipeline you should select top entry design ball valves for in line maintance and quick repairability. It allows to remove ball and seats easily at site without disassembly whole valve for maintance or repairing purpose.
 
Size:2"--24" Pressure:150#--1500# Product Material:Carbon&Lowalloy steel/STL/Nickel bare alloy Description Top entry ball valve gives the advantage of in-line repair or replacement of valve internal components without removing the valve from the pipeline. This is why this valve is frequently used on high pressure pipeline, especially with heavy oils, where relatively frequent cleaning is needed, thus minimizing the disassembly and re-assembly of valves with a remarkable cost saving. More, it minimize the leakage path and eliminate any potential contacts between threads and wetted parts. Features 1. One piece body design 2. Fire-safe & antistatic 3. In-line repair 4. Less leakage path compared to side entry design 5. Double block and bleed(DBB) function 6. Emergency sealant injection system 7. Stem/bonnet extension for cryogenic service Standard Design and manufacture to API 6D, BS 5351, API 608 Face to face to API 6D or ASME B 16.10 Flange Ends to B 16.5 Test and Inspection to API 6D or API 598.

Top entry trunnion ball valves in cast steel one piece body with 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.
 
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.
