Resilient Seal Gate Valve, Double Flanged, Waterworks purposes, Non-Rising Spindle, Class 10 & 16


  • An outstanding resilient seal gate valve manufactured under licence to Bopp & Reuther GmbH of Mannheim Waldhof, West Germany.
  • Accurately-moulded and completely rubber-coated spheroidal graphite iron gate ensures droptightness from zero to maximum working pressure even under the most adverse working conditions. The gate is designed for minimum distortion of the resilient seal, equal distribution of sealing pressure in all directions with a capacity to accept foreign matter and still seal tight.
  • Straight, unobstructed body passage without pocket as well as inclined seats and gate guides eliminate deposits in valve body.
  • Long and accurate guides fully support gate in all positions.
  • Corrosion-resistant spindle seal consisting of standard O-rings in plastic bush and an additional scraper ring to prevent ingress of dirt.
  • Back seal permits replacement of spindle seals under pressure.
  • Replaceable, corrosion-resistant spindle nut in gate.
  • Spindle thrust collar located between anti-friction materials ensures low operating forces.
  • Highly resistant to corrosion and abrasion.
  • Modern shell-moulding process ensures accurate, interchangeable components, smooth surfaces and increased corrosion-resistance.
  • Epoxy coated (other finishes available as optional extra).
  • Easy maintenance. All components readily replaced by unskilled personnel without special tools and without removing the valve body from the pipework.

Unless otherwise specified:

  • Flanges drilled to the nominal pressure class of BS 4504
  • Clockwise closing.
