The V-port control ball valve is a type of ball valve featuring a V-notch on its hemispherical closure element. The sharp-edged V-notch provides a shearing function during rotation, delivering strong shut-off capability against media flow.
Product Overview
The V-shaped opening and valve seat flow passage form a sector-shaped area, enabling precise flow regulation by varying the flow cross-section during operation. As a rotary-controlled valve, it maintains the same sealing performance as standard ball valves while combining both regulating and shut-off functions. When paired with pneumatic or electric actuators, it becomes an ideal solution for industrial automation systems. Widely used in processes requiring: Accurate flow control. High shut-off reliability, Abrasive/slurry media handling. This design is particularly effective in pulp & paper, mining, and wastewater treatment applications where both modulation and tight shut-off are required.

| Features | Description |
| One-Piece Body | Monobloc body design with integral wafer/flange connections, offering superior rigidity to prevent deformation and external leakage. |
| Rotary shearing Function | The V-notch ball design effectively shears fibers and fine particles in the medium, preventing valve clogging. |
| Precision Regulation | The V-port design provides exceptional regulating performance, delivering near-equal percentage flow characteristics with a turndown ratio of 300:1. |
| Stem Guiding Structure | Advanced stem-guided ball drive system, guidance with self-lubricating bearings, reducing friction resistance while lowering operating torque and enhancing valve efficiency and service life. |
| Shape-Memory Alloys | The monolithic shape-memory alloy seat effectively eliminates seal failure caused by spring fatigue in traditional spring-energized seats. |
| Superior Sealing | The ball and seat surfaces are hardfaced with Stellite or other wear-resistant alloys, delivering superior abrasion resistance. |
| Standard Mounting Platform | Design with deep packing box and cast bracket isolates actuator from body heat, maintaining ISO 5211 compliance for universal pneumatic/electric actuator compatibility. |
