Q11FThree piece internal thread ball valves are divided into integral one-piece, two-stage, and three-stage types. The valve body casting adopts advanced technology introduced from Taiwan, with a reasonable structure and beautiful appearance. The valve seat adopts an elastic sealing structure, which is reliable in sealing and easy to open and close. The valve stem adopts a bottom mounted structure with reverse sealing, and the valve stem will not be flushed out when the valve chamber is abnormally pressurized.

The connection form of the three piece ball valve also includes butt welding(BW)socket weld(SW),And both can carry international standardsISOBracket platform and locking device. Can be set90° switch positioning mechanism, locked as needed to prevent misoperation, driving mode:Manual, electric, pneumatic.

Choose different materials,It can be applied to various media such as water, steam, oil, nitric acid, acetic acid, etc. Three piece internal thread ball valve and butt welded connection ball valve are suitable forPN1.0～4.0MPaWorking temperature-29～180℃(The sealing ring is reinforced with polytetrafluoroethylene)or-29～300℃(The sealing ring is made of para polystyrene)Used to cut off or connect media in various pipelines

IIstructural characteristics：
