The core of the pneumatic V-shaped regulating ball valve is designed with a special V-shaped notch, which has a shearing effect on the valve seat. It is particularly suitable for media containing fibers, small solid particles, slurry, etc. According to different structural methods, it can generally be divided into flange and clamp types; Pneumatic V-shaped ball valve belongs to fixed ball valve and single seat sealed ball valve. Its regulating performance is the best among ball valves, and it can achieve flow regulation. At the same time, due to the seamless rotation between the valve core and valve seat, it can wipe the accumulated dirt on the ball and valve seat by itself, maintaining a good seal between the ball and valve seat.
