Top Entry Ball Valve

Top entry ball valve is a rotary switch valve that controls the on/off of the medium by rotating the ball. The 90-degree rotation of the sphere allows the medium to pass through or close the channel inside the sphere, thus achieving the control of the medium.

  1. Top entry ball valve is valve Installing ball into valve body by the upper for repairing conveniently.
  2. Top entry ball valve adopts elastic interface structure, which can adapt to different deviations of the pipeline, and increase the tightness and life of the valve.
  3. The valve stem adopts self-sealing structure to improves the reliability and tightness.
  4. It can be made of different materials, and is suitable for use in various media, pressure and environments.
