Three-piece ball valve with external thread is a multi-connection ball valve integrating welding and external thread. Easy installation and disassembly, fastening connection, conducive to fire, explosion and high pressure resistance, online cleaning or maintenance. Suitable for air, steam, water, gas, petroleum and petrochemical products, corrosive media, etc.
The ball valve is suitable for PN1.0 ~ 4.0MPa, working temperature -29 ~ 150℃(sealing ring for enhanced polytetrafluoroethylene) or -29 ~ 300℃(sealing ring for para-polystyrene) of various pipelines, used to cut off or connect the medium in the pipeline. Choose different materials, can be respectively suitable for water, steam, oil, nitric acid, acetic acid and other media.
Product features:
1. The fluid resistance is small, and its resistance coefficient is equal to that of the pipe section of the same length.
2, Simple structure, small size, light weight.
3, Tight and reliable, the sealing surface material of ball valve is widely used in plastic, good sealing, and has been widely used in vacuum system.
4, Easy to operate, open and close quickly, from fully open to fully closed as long as the rotation of 90°, easy to remote control.
5, Convenient maintenance, ball valve structure is simple, sealing ring is generally active, disassembly and replacement are more convenient.
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.
