Ball Check Valves

Ball Valves are a simple and highly effective solution for preventing backflow, especially in systems handling wastewater, slurries, or debris-laden fluids. With only one internal moving part—the rubber-coated ball—these valves provide reliable, low-maintenance performance in a wide range of industrial and municipal applications.

We supply Ball Check Valves to all cities in Australia, including Perth, Adelaide, Melbourne, Sydney, Brisbane, Darwin, Canberra, and Hobart. Contact us on 1300 271 290 or use our online enquiry form for advice, pricing, and technical support.


Key Benefits

  • Self-Cleaning Design: The internal ball rotates during flow, reducing buildup and preventing clogging.
  • Full Bore Opening: Allows unrestricted flow with minimal pressure loss.
  • No Springs or Hinges: Fewer components means less wear and longer service life.
  • Low Back Pressure Required: Only minimal reverse pressure is needed to achieve tight closure.
  • Horizontal or Vertical Installation: Flexible positioning suits various pipeline layouts.
  • Low Maintenance: Ideal for remote locations and unattended systems.

Technical Details

  • Machined seat for precise ball fit—ensures 100% leak-tight seal
  • Suitable for low-pressure applications (e.g., up to 1600kPa)
  • Available in Cast Iron and Stainless Steel body options
  • Threaded and flanged versions available (AS2129 Table D/E, AS4087 PN16, ANSI 150LB)
  • Tested to 24 Bar body and 16 Bar seat pressure
  • Sizes available up to DN600 on request

Where to Use a Ball Check Valve

Ball Check Valves are ideal for use in:

  • Wastewater treatment and drainage systems
  • Pumping stations with potential for solid or fibrous debris
  • Industrial and chemical processes
  • Slurry, stormwater, or greywater applications
  • Remote or infrequently serviced sites

Installation Guidelines

  • Install according to the flow direction marked on the valve body.
  • Ensure the ball rests correctly in the seat when no flow is present.
  • If installed in reverse, the valve will prevent flow entirely.
  • Ball Check Valves can be installed horizontally or vertically depending on system design.
