V-Port Ball
V-Port Ball
V-port ball is the core component of V-port control ball valve. It features a V-shaped notch flow passage on the ball surface, integrating functions of throttling, flow regulation and tight shutoff.
Structure & Working Principle
Designed with a precise V-cut notch instead of straight round bore.
The V-shaped opening changes linearly with rotation angle, realizing accurate flow regulation.
When fully closed, the V-edge fits closely with the valve seat for excellent tight shutoff performance.
Built-in shearing function: the V-notch and seat can cut fiber, slurry and solid particles to avoid jamming and blockage.

Detail
Material & Process
Materials: 304, 316L, 443, duplex steel, alloy steel and special stainless steel.
Manufactured by forging or investment casting, CNC V-port machining and mirror precision lapping.
Optional surface treatment: nitriding, hard chrome plating, Stellite hardfacing for high wear, corrosion and temperature resistance.
Key Advantages
- Precise flow control with equal percentage flow characteristic, stable regulating performance.
- Self-shearing design prevents blockage from fiber, slurry and solid impurities.
- Excellent tight shutoff ability with low leakage rate.
- High erosion and wear resistance for high flow speed and corrosive media.
- Suitable for pneumatic and electric actuators, ideal for automatic control systems.
Applications
Paper & pulp, chemical slurry, sewage treatment, coal ash slurry, textile printing and dyeing, food industry and industrial pipelines requiring regulation and cut-off with particle media.
V-Port Ball valves are commonly used in acid transfer, agriculture, bleach chemicals, water treatment, leaching acid, pharmaceuticals, waste processing and food processing.
