Ball Segment Valves

For Use as a discharge valve or isolation valve

The unique properties of the Ball Segment Valves are that it can handle both liquid and dry abrasive products from fine powder to coarse abrasives. It has an opening where materials cannot build up, accumulate, or be captured within the valve body.

The Ball Segment Valves are used in a wide range of applications in the pharmaceutical, chemical, food and mining industries.

The valve can be supplied with an optional full fail-safe system. In this case, the valve closes whenever there is a loss of electric power or compressed air/nitrogen. When a failure occurs, a pressurized accumulator tank filled with air/nitrogen closes the valve. After the valve is closed, the inflatable seal is pressurized to close the space between the Ball Segment and the valve housing. Our Ball Segment Valve can be supplied with an inflatable seal or static teflon seal.

There are two main advantages of the inflatable seal

  • Reduced wear and tear because the seal is inflated when the valve is fully closed and deflated before the valve is opened
  • Withstand pressure up to 10 bar and full vacuum.
The Unique Features
  • Full bore to allow maximum flow
  • Ability to open and close with static or flowing material
  • Standard sizes up to 12″ (300 mm).
  • Larger sizes available up to 20″ (500 mm) on request.
  • Designed for full vacuum and overpressure in both directions
  • Seals made of high chemical resistant perfluoroelastomer FDA compliant materials
  • Can operate in temperatures up to 400ºF or 230ºC
  • Inflatable seal to prevent jamming and leaking
  • Seal inflates only when valve is fully closed and deflates upon opening of the valve, therefore eliminating unnecessary wear and tear to insure longer seal life.
  • Inflatable seals to reduce opening and closing torque requirements
  • Special design to eliminate product build-up on seal face
  • Manual or pneumatically operated
  • Can be supplied with positioner actuator with monitoring
  • Valve body polished and constructed for pharmaceutical and food applications
