A V port ball valve is a special type of ball valve, its core feature being the V-shaped notch in the flow passage of the valve core (ball). Unlike ordinary full-bore or reduced-bore ball valves, the V-shaped notch design gives this valve superior performance in flow regulation.
When the valve is opened, as the valve stem rotates the ball, the V-shaped notch gradually aligns with the pipe flow passage, causing the cross-sectional area through which the fluid passes to change linearly or by an equal percentage, thus achieving precise control of the medium flow rate. This characteristic makes V-type ball valves widely used in industrial systems requiring precise regulation, such as those in the chemical, paper, water treatment, power, and metallurgical industries.

V port ball valve features
V-shaped notch design
A V-shaped notch is formed on one side of the ball core, creating a wedge-shaped shearing effect with the metal valve seat. As the ball core rotates, the flow area between the V-shaped notch and the valve seat continuously changes, achieving flow regulation. This design gives the valve self-cleaning capabilities, cutting off fibrous impurities and preventing media accumulation.
Fixed ball structure
The fixed ball design prevents the ball from moving with pressure, reducing friction and wear and extending service life. The valve seat is spring-loaded, ensuring reliable sealing with a leakage rate ≤10⁻⁶ × rated flow coefficient.
Eccentric structure and hardening treatment
Some models (such as the V1000V hard-seal eccentric V-type regulating ball valve) feature an eccentric design. The ball core surface is treated with hard chrome plating, ion nitriding, or supersonic spraying to improve surface hardness and enhance wear resistance and corrosion resistance.

V port ball valve Performance Advantages
Precise Control Capability
The flow characteristic is approximately equal percentage, with an adjustable ratio from 100:1 to 300:1, providing precise control over a wide range of operating conditions. For example, in the pharmaceutical industry, it ensures constant fluid flow to meet stringent dosage requirements.
Low Resistance and High Flow Capacity
The streamlined valve body design reduces fluid resistance and provides high flow capacity, allowing for economical operation with smaller valve sizes. Simultaneously, the dual-bearing structure reduces starting torque, ensuring sensitivity and mechanical stability.
Media Resistance
Suitable for media containing fibers, small solid particles, and slurries, such as pulp, sewage, and mineral slurry. The shearing force of the V-shaped notch effectively prevents clogging and avoids valve jamming.
Sealing and Reliability
The metal hard seal structure combined with the elastic load pressure-assisted sealing seat ensures long-term sealing performance. The valve body is an integral structure with high rigidity, reducing the risk of external leakage, and operation is unaffected by pipeline pressure.
