Techincal Information

Usage & Features

Applications

Clover resilient seat double flange integral bypass gate valves PN16 are suitable for use in pressure and non-pressure water supply and sewerage applications. Gate valves are used to isolate flow within pipeline sections, pipeline equipment and offtakes.

Typical applications include;

  • Potable and recycled water supply
  • Irrigation and raw water
  • Gravity and sewer rising mains
  • Fire systems
  • Stormwater and drainage
  • Buried and above ground

Gate valves should not be used for the purposes of throttling or adjusting flow.
