Characteristics of V-type flange regulating ball valve
1. The V-notch ball core and the metal valve seat have shear effect, which is especially suitable for media containing fibers, small solid particles, slurry and so on;
2. The V-type cut-off ball valve driven by worm gear also has the ability of adjustment and reliable positioning, the flow characteristic is approximate percentage, and the adjustable range is wide;
3. The movable valve seat structure loaded by leaf spring can prevent the valve seat from sticking or separating from the ball core. The seal is reliable and the service life is long.
