Main features

The three-piece carbon steel ball valve is divided into butt welding (BW) socket welding (SW), and the valve body casting adopts the advanced technology introduced by Taiwan, with reasonable structure and beautiful appearance. 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. When the valve cavity is abnormally boosted, the valve stem will not be flushed out. Both can be equipped with international standard ISO bracket platform and locking device. It can be set with 90° switch positioning mechanism, and can be locked according to need to prevent misoperation. Drive mode: manual, electric and pneumatic.
