Q11F PN16~PN63Introduction to two-piece internal thread ball valve

Q11F PN16~PN63Two piece internal thread ball valve is a relatively new type of ball valve, which has some unique advantages in its own structure, such as frictionless switch, low sealing wear, and small opening and closing torque. This can reduce the specifications of the accompanying actuator. Equipped with a multi turn electric actuator, it can achieve adjustment and tight cutting of the medium. Widely applicable to working conditions that require strict cut-off of water supply and drainage in petrochemical cities

Q11F PN16~PN63Characteristics of two-piece internal thread ball valve

Internal threaded ball valves and butt welded ball valves are divided into integral types(One-piece type)Two stage and three stage. The valve body casting adopts advanced technology introduced, 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. Two piece and three piece ball valves can also be connected by 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.
