BALL

Ball Valve Part: Ball

The ball is the central rotating component inside a ball valve that controls fluid flow. Shaped as a hollow sphere with a through-hole (bore), it allows flow when aligned with the pipeline and blocks flow when rotated 90 degrees to the closed position.

Function of the Ball

• Flow Control
  Rotates within the valve body to open or close the passage, providing quick and reliable on/off control.

• Sealing Interface
  Works in conjunction with the valve seats to create a tight seal, preventing leakage when closed.

• Pressure Handling
  Designed to withstand system pressure and ensure smooth operation under various temperature and flow conditions.

Key Features

• Material
  Commonly manufactured from stainless steel, carbon steel, chrome-plated steel, or other corrosion-resistant alloys for durability and corrosion resistance.

• Surface Finish
  Precision machining and polishing reduce friction and wear, enhancing sealing and operational life.

• Bore Types

  • Full Bore: The bore diameter equals the pipeline diameter, minimizing pressure drop.

  • Reduced Bore: Slightly smaller bore to reduce valve size and cost.

  • V-Port: A V-shaped cutout for precise flow control and throttling.

• Mounting
  Mounted on a stem that allows 90-degree rotation to control flow.

Applications

• Used extensively in oil & gas, chemical processing, water treatment, HVAC, and other industries requiring reliable flow shutoff and control.

• Selected based on compatibility with process media, pressure, temperature, and flow requirements.
