ANSI TRUNNION MOUNTED BALL VALVE

ANSI Trunnion Mounted Ball Valve Descriptions

ANSI trunnion mounted ball valve is one type of API flanged ball valve with split body structure, which is normally used for bigger sizes ball valve with high pressure. According to body structure, ASME B16.34 trunnion mounted ball valve can be divided into two pieces flanged ball valve or three pieces flanged ball valve with materials of carbon steel (A216 WCB), stainless steel 304(A351 CF8), 316(A351 CF8M), bronze (C83600), duplex SS . We can manufacture and supply the ANSI trunnion mounted ball valve in accordance with ASME B16.34, API608,  API6D with sizes of 2″~60″ (DN50~1500mm), and special request of NACE MR01-75 and API607 & API6F are available.
