Pneumatic segmented ball valve
Overview of Pneumatic segmented ball valve
Pneumatic segmented ball valve adopt cylindrical spring preloaded movable metal seat structure with compensation, with good sealing performance. The ball core and the valve seat will not be blocked or separated, and the service life is long. The V-shaped notch on the ball core has shear effect with the metal valve seat, which is suitable for controlling high viscosity media including fiber, solid particles and slurry. The paper pulp of structure manufacturing paper industry is superior. The valve has large flow capacity, small pressure loss, and the medium will not be deposited in the cavity of the valve body. The valve has approximately equal proportional flow characteristics, large adjustable range, and also has the function of adjustment and positioning.

Features of Pneumatic segmented ball valve
1. The utility model has the advantages of compact structure, small volume, vertical and horizontal installation, etc.
2. It has excellent regulation characteristics: the V-shaped ball valve has an approximately equal percentage of natural flow characteristics and an adjustable ratio of up to 300:1..
3. Large flow volume: due to its streamlined shape and full right angle rotation control, the large value of volume is particularly high, the flow capacity is particularly large, and the flow resistance is small. Therefore, smaller and more economical valve sizes can be used.
4. The V-type ball valve adopts double bearing structure, with high mechanical stability and small starting torque, which ensures that the valve has excellent sensitivity and induction speed.
5. Great reliability (safety): the valve body is a whole, solid and durable, the operation is not affected by the pipeline pressure, and the valve body leakage can be avoided.
6. Superior sealing performance of metal valve seat: the V-shaped ball valve adopts movable metal valve seat with self-service compensation function, and has superior sealing performance and long service life
