Pneumatic V-Port Ball Valve - Product Description

Overview: A Precision Solution for Advanced Flow Control

Our Pneumatic V-Port Ball Valve is an engineered control valve designed for applications requiring precise modulation and superior control of various media, including slurries, powders, and viscous fluids. Unlike standard on/off ball valves, its characterized V-notch ball and advanced pneumatic actuation make it the ideal choice for demanding processes in industries such as chemical processing, pulp & paper, power generation, and wastewater treatment.

Key Features & Benefits:

• Precise Flow Control & Characterization
  The core of the valve is the precision-machined V-notch ball. This design provides an accurate, linear flow characteristic that is nearly proportional to the stroke, allowing for excellent control and stability, especially in throttling applications.

• Shearing Action & Anti-Clogging Design
  The sharp-edged V-ball shears through fibrous materials and semi-solids during rotation, effectively preventing clogging and ensuring reliable operation in handling slurries, pulp, and other challenging media.

• High Capacity & Rangeability
  The optimized flow passage offers high capacity and exceptional rangeability, meaning the valve can maintain precise control over a wide range of flow rates, from low to full capacity.

• Robust & Long-Lasting Construction

  • Actuator: The pneumatic actuator is manufactured from extruded aluminum alloy and undergoes a hard-anodized surface treatment for exceptional corrosion resistance and durability.

  • Wear-Resistant Support: All moving parts are supported by wear-resistant materials, significantly extending the service life and reducing maintenance needs.

  • Stem & Sealing: A robust stem design and high-performance sealing materials (such as PTFE, RPTFE, or Metal Seated options) ensure tight shut-off and minimal fugitive emissions.

• Bidirectional Shut-Off
  The valve provides reliable, bubble-tight shut-off in both flow directions, enhancing system safety and integrity.
