Product description

The three-piece ball valve is suitable for cutting off or connecting various pipelines with a working temperature of -29~180°C (the sealing ring is reinforced polytetrafluoroethylene) or -29~300°C (the sealing ring is para polystyrene). medium in the pipeline. Different materials are selected, which can be applied to various media such as water, steam, oil, nitric acid, and acetic acid.

Features

Three-piece ball valves are divided into integral (one-piece), two-stage and three-stage types. Reasonable structure and beautiful shape. The valve seat adopts elastic sealing structure, which is reliable in sealing and easy to open and close. The valve stem adopts a bottom-mounted structure with an inverted seal, and the valve stem will not be flushed out when the valve cavity is abnormally boosted. Two-piece and three-piece ball valve connections are also butt welding (BW) and socket welding (SW), and can all have international standard ISO bracket platform and locking device. 90° switch positioning mechanism can be set, lock as needed to prevent misoperation, drive mode: manual, electric, pneumatic.
