Forged Square Ball Valve
Features
1. Small body resistance, and the full bore basically has no flow resistance.
2. Simple structure, economical and practical, convenient and fast installation.
3. Tight and reliable, good sealing performance, the ball can be well sealed with the valve body, sealing good in pipeline engineering.
4. Easy to operate, fast opening&closing, only need to rotate 90° from fully open to fully closed, which is convenient for long-distance control.
5. The maintenance is convenient, simple structure of the ball valve, the sealing ring is generally movable, and it is more convenient to disassemble and replace
6. Good corrosion resistance. When fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium. When the medium passes through, it will not cause erosion of the valve sealing surface.
7. Due to the wiping property of the ball valve in the opening and closing process, all can be used in the medium with suspended solid particles.
8. The Q81F ball valve can be locked to prevent the danger caused by misoperation.
Applications
It is widely used in various industries such as chemical industry, electromechanical engineering, machinery manufacturing, shipbuilding, electric power, petrochemical, metallurgy, plumbing, water treatment, mechanical equipment manufacturing, pneumatic pipelines, hydraulic pipelines, etc.
