Screw Ball Valve
Threaded ball valves and welded ball valves are divided into integral (one-piece) type, two-section type and three-section type.
Product Introduction
lntroduction of Inner-threaded ball valve£º
Threaded ball valves and welded ball valves are divided into integral (one-piece) type, two-section type and three-section type. The valve body casting adopts advanced technology introduced from Taiwan, with reasonable structure and beautiful appearance. Valve seat adopts elastic sealing structure, reliable sealing, easy to open and close. The valve stem adopts downward sealing structure, when the valve chamber abnormal pressure is boost, the valve stem will not be rushed out. Two - piece, three - piece ball valve connection form have butt welding (BW) socket welding (SW), and can be with international standard ISO support platform and locking device. 90¡ã switch positioning mechanism can be set, which can be locked according to the need , in case of misoperation, drive mode: manual, electric, pneumatic.

1, The fluid resistance is small and its resistance coefficient is equal to that of a pipe section of the same length.
2, It has simple structure, small volume, light in weight.
3, Tight and reliable, its' the sealing surface material is widely used in plastic, good sealing, and has been widely used in vacuum system.
4, It is easy to operate, open and close quickly, from fully open to fully closed as long as the rotation of 90¡ã, convenient for remote control.
5, Convenient maintenance, the ball valve structure is simple, sealing ring is generally active, more convenient disassembly and replacement.
6, When fully open or fully closed, the sealing surface of the ball and seat is isolated from the medium. When the medium passes, it will not cause the erosion of the sealing surface of the valve.
7, A wide range of applications: from small diameter to a few millimeters, to a few meters, from high vacuum to high pressure applications.
