Introduction to VQ947H-300LB Electric Adjustable V-Ball Valve Pneumatic adjustable V-shaped ball valve is a type of ball valve, with a V-shaped opening on the hemispherical body as the closing element. The V-shaped opening has a sharp cutting edge, and during the rotation of the ball, there is a wiping effect between the closing elements, which has a strong cutting force on the medium. The V-shaped opening of the ball and the valve seat flow channel form a fan-shaped area. During the rotation process, the cross-sectional area of the flow channel can be changed to form precise adjustment of the medium. It is an angle rotating regulating valve with the same sealing performance as ordinary ball valves, which enables it to have both regulating and switching functions. It is widely used in industrial process control systems and is matched with pneumatic or electric actuators.
