Top Entry Ball Valve

Top Entry Ball Valve

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
