Product Overview

The O-type ball control valve features a full-bore or reduced-bore O-shaped ball design driven by a pneumatic actuator, providing excellent flow capacity (high Cv) and precise proportional control. Its straight-through flow path minimizes pressure drop while delivering smooth throttling performance.

Wuxi Quankong offers O-type ball control valves in sizes from DN25 to DN600, with options for V-port trim for enhanced rangeability and cavitation resistance.

Key Features

  • High Flow Capacity: Full-bore design provides near-zero pressure drop at full open
  • Precise Modulation: Integrated smart positioner enables accurate proportional control
  • Wide Rangeability: Optional V-notch ball trim for up to 300:1 turndown
  • Low Maintenance: Self-lubricating seats and blowout-proof stem design
  • Dual Sealing: Fire-safe design with metal secondary seat per API 607
