overview
The V-shaped regulating ball valve has a shear effect on the valve seat due to the V-shaped structure of the ball core. Therefore, it is suitable for controlling relevant process parameters in suspension media containing fibers or small solid particles in industrial enterprises such as papermaking, chemical, metallurgical, etc. It is particularly suitable for automatic adjustment of suspended particles such as pulp, white water, black liquor, white liquid, and concentrated and turbid slurry fluid media in pulp and paper production processes
characteristic
1. Equipped with elastic load pressure auxiliary sealing seat to ensure tight contact between the valve seat and the ball core from the beginning to the end
2. With a one-piece valve body structure, there is no possibility of potential leakage
3. Having equal percentage characteristics, a wide control range, and particularly stable control processes, it can be widely used in various process flows
4. The valve stem and ball core are connected by involute splines. When the tooth profile is loaded, there is a radial force on the teeth that can automatically center them, and the force on each tooth is uniform, resulting in high strength and long service life
