High Performance V Type Control Ball Valve API607 API6d Ce
The V-type ball valve is a specialized type of ball valve designed for precise flow control. Its closure element features a V-shaped cut on the spherical segment, which creates a shearing action with the seat as the sphere rotates. This design provides strong cutting force and enables accurate regulation of media flow. The V-shaped opening works in conjunction with the seat to form a sector-shaped flow channel, allowing for continuous adjustment of the cross-sectional area and precise control of the media.
This valve combines both control and shut-off functions, offering the same sealing performance as standard ball valves. When equipped with a pneumatic or electric actuator, it is widely used in industrial process control systems. Its design ensures reliable operation and durability, making it suitable for a variety of applications.
Key Features:
- **Integral Body Structure**: The body uses an integral side-entry design, providing excellent structural rigidity and minimizing the risk of external leakage.
- **Self-Lubricating Bearings**: Upward and downward bearings reduce friction, lowering the operating torque and improving overall performance.
- **Versatile Sealing Options**: The seat can be either metal-hard sealed or PTFE soft-sealed, depending on the application requirements. Metal seals are treated with hard alloy overlay welding, while PTFE seats offer superior corrosion resistance and sealing performance.
- **High Performance-to-Cost Ratio**: The lightweight body and low stem torque make it energy-efficient and cost-effective compared to other types of control valves.
- **Adaptability to Media**: The V-shaped design prevents media from depositing in the cavity, making it ideal for use with liquids, fibers, and solid particles.
- **Precise Flow Control**: Small Cv values allow for fine-tuned flow control through the V-notch design in smaller plugs.
