vee ball valve Description
The V-type ball valve is a valve that achieves flow regulation and cutoff by rotating the ball with a V-shaped cutout, and has both switching and regulating functions. Its core design is adapted to the precise control of fiber-containing, particle-containing or viscous media through the shearing effect of the V-shaped cutout and the valve seat, and the adjustable ratio is up to 100:1.
Core structure
Ball: V-shaped cutout design is adopted, and the cross-sectional area of the flow channel is changed by the rotation angle to achieve linear or equal percentage flow regulation; Valve seat: metal or polytetrafluoroethylene material, tightly matched with the ball to ensure high-pressure sealing; Actuator: can be configured with electric or pneumatic (such as cylinder or diaphragm) drive, supporting automatic control.
Working principle
When the ball rotates 0°~90°, the V-shaped cutout and the valve seat form a gradual flow area, achieving precise flow regulation and rapid cutoff.

Difference from O-type ball valve
Functional difference
V-type: mainly for adjustment function, taking into account the switch, suitable for precise control of impurity-containing media;
O-type: mainly for fast switching, full-diameter design with small flow resistance, suitable for clean media cutoff.
Structural design
V-type ball: single-sided V-shaped cutout, flow rate is adjusted by rotation angle;
O-type ball: circular through hole, the flow channel is equal to the pipe diameter when fully open, and there is no throttling effect.
Applicable scenarios
V-type: high viscosity or particle-containing systems such as papermaking and sewage treatment;
O-type: fast cutoff scenarios for clean media such as oil and natural gas.

Applicable media and industry applications
Applicable media
Liquids, gases, steam, slurries, fluids containing particles (such as pulp, sewage, powder).
Industry applications
Chemical and petroleum: flow control and cutoff of corrosive media (such as acid, alkali, urea);
Environmental protection and water treatment: regulation and emission control of sewage and media containing solid particles;
Food and pharmaceuticals: aseptic regulation of sanitary fluids (polishing of valve body is required);
Energy and metallurgy: flow management of high-temperature steam, natural gas pipelines and blast furnace gas.
