Pneumatic V-shaped regulating ball valve is a rotary ball valve with a core seat made of metal or metal to PTFE sealing and matching. It combines the best control characteristics of the ball valve and butterfly valve into one, and can be used as both a control regulating valve and a shut-off valve.
Product Feature.
1. The shear force between the ball and the metal seat type V incision, especially suitable for containing fiber and small solid particle, pulp and other medium.2. Fully open flow capacity, small pressure loss, and the media will not deposit in the body cavity.
3. Using a spring-loaded movable seat structure , Preventing the occurrence of ball core and valve seat from jamming or other issues, reliable sealing and long service life.
4. The valve has the advantages of accurate regulation and reliable positioning function, approximately equal percentage flow characteristics, large adjustable range, the maximum adjustable ratio 100:1.
