The main feature of T-type fully welded ball valves is the integrated welded connection between the pipeline and the valve body, which avoids the possibility of leakage and is therefore widely used in the petroleum, natural gas, chemical industry, food and pharmaceuticals, electric power, water and wastewater treatment and other industries. Since T-type fully welded ball valves can not be disassembled for maintenance, it is necessary to fully consider the requirements and maintenance of piping systems when choosing and using them to ensure the applicability and reliability.

T-type fully welded ball valve is a three-piece side-mounted forged welding structure, forged steel fixed ball floating seat, soft/hard dual-stage seal, primary seal for metal seal, secondary seal for non-metallic seal; valve fire test according to API607 and BS6755 provisions of the anti-static, with the valve stem to prevent blowing out function.

T-type fully welded ball valve opening and closing parts (ball) driven by the valve stem, and around the ball valve axis for rotary motion of the valve. Can be used for fluid regulation and control, in which the hard seal V type ball valve in the V type ball core and surfacing hard alloy metal valve seat has a strong shear force, especially for the media containing fibers, tiny solid particles and so on.
