Product Name
Two-piece ball valve, Stainless steel two-piece ball valve
Two-piece Ball Valve Feature
Q11F two-piece ball valve body casting adopts advanced technology imported from Taiwan, with 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 an inverted seal. When the valve cavity is abnormally increased in pressure, the valve stem will not be flushed out.
Two-piece ball valve connection forms also have butt welding (BW) socket welding (SW), and both can be equipped with international standard ISO bracket platform and locking device. A 90° switch positioning mechanism can be set, and it can be locked as required to prevent misoperation. Drive mode: manual, electric, pneumatic.
