Product Introduction


  KPQ340Y-16C skewed hemispherical ball valve is a new generation of high-performance ball valve, it is widely used in long-distance pipelines and general industrial pipelines. Compared with the floating ball valve, the working force of the medium pressure in the pipeline before the valve on the ball is transmitted to the upper and lower bearings, the ball will not move relative position, and the valve seal ring should have sufficient pretension by the spring force. To ensure the sealing of the valve, the sealing surfaces at both ends of the product are evenly stressed, the operating torque is low, the sealing performance is safe and reliable, and the service life is long. The item is particularly suitable for long-distance pipelines and urban gas supply projects.

Features of Skewed Hemispherical Ball Valve

  1. The structure of the product uses the principle of eccentric tightening, through the transmission mechanism to tighten, adjust and close the valve. The sealing pair is a metal face ring with hard surface contact sealing. The double skewed structure is located in the hidden ball chamber when it is opened. The flow cross-section is large, and the valve is not washed away. The valve core is not washed when closed. When opened, the spherical surface of the valve core is progressive along the valve seat, effectively removing the scaling obstacles, and achieving reliable sealing. It is particularly effective for the mixed flow transportation of two-phase mixed flow that is prone to scaling solid precipitation.

  2. The hemisphere of the valve is made of bimetal, and different alloys are welded on the base metal. The valve seat is also subjected to special treatment for surfacing welding, and the sealing surface is combined into various types such as corrosion resistance, wear resistance, high strength, etc. Which can meet the needs of different occasions.

  3. The reliable sealing performance make sure that there is no any leakage during conveying harmful gases.

  4. The valve core of the sealing pair has a compensation amount. When the valve seat is worn, people just need to rotate a little more when it is closes, its sealing performance is still reliable. In addition, the user unscrews the compression nut, and the valve seat can still be reused after adjustment or replacement, avoiding the disadvantage of the entire unit being scrapped after the valve seal fails.Surfacing welding of different alloy (or combination balls) bimetallic seal pairs can be used in wear-resistant, corrosion-resistant, high-temperature resistant and strict sealing conditions.

Threaded Ball Valve Has the Following Advantages

  1. The fluid resistance is small, and the resistance coefficient is equal to that of the pipe section of the same length.

  2. Simple structure, small size and light weight.

  3. It is tight and reliable. The sealing surface material of ball valve is usually made of plastic, which makes the product having good sealing performance. It is also widely used in vacuum system.

  4. It is easy to operate and quick to open and close. It only needs to rotate 90° from fully open to fully closed to facilitate remote control.

  5. The maintenance is convenient, the structure of the ball valve is simple, the sealing ring is generally movable, which makes the disassembly and replacement more conveniently.
