Segment Ball Valve Overview:

The V-type ball valve is a rotary shutoff valve featuring a V-shaped gap in the core. When used with a valve positioner, it enables precise ratio adjustment. It is widely utilized across petroleum, chemical, paper-making, metallurgy, and water treatment industries to regulate or cut off pipeline media. It boasts a high flow coefficient and a booster ring at the valve seat for adjustable sealing force, ensuring a tight seal.

Key Product Features

  • Reliable Sealing: Movable spring-loaded valve seat structure prevents jamming or severing between the ball core and seat, extending service life.
  • Anti-Clogging Design: The shearing action between the V-shaped notch ball core and metal seat makes it ideal for media containing fibers, micro-solids, or pulp.
  • High Efficiency: When fully open, it provides large flow capacity with minimal pressure loss, preventing sediment deposition in the valve cavity.
  • Precise Control: Offers reliable positioning with equal percentage flow characteristics and a wide adjustable ratio of up to 100:1.
