D7 Inflation / Deflation Valve

  • High flow.
  • Smooth, low profile cap.
  • Compact internal profile to prevent damage to fabric.
  • Extremely rugged and reliable.
  • The core includes an 'O' ring to optimize sealing on fabric.
  • Core can be removed from the outside of the tube for cleaning.
  • Cap acts as a secondary seal.
  • 100% tested during production.
  • High quality materials to ensure long life.

The Leafield Marine D7 valve is designed to replace the highly successful C7 Valve - the favoured inflatable boat valve for use in demanding applications such as Military and Commercial RIBs, River rafts and Inflatable Boats.

The new D7 Valve has several benefits over the previous model with improved inflation/deflation speed. It has an enhanced clamping method with an ‘O’ ring seal added to the valve core to reduce the risk of leaks.

ACETAL (POM) plastic parts give high strength, chemical and ozone resistance.

The seal is designed so that it cleans the seal surface as it operates; this also reduces the risk of leakage due to dirt contamination.

When the cap is fitted the rugged retaining strap is hidden from view to prevent snagging on other equipment. Simple cap replacement - it does not require the valve to be removed.

The D7 valve has a shorter internal profile than other valves making it ideal for smaller diameter tubes, for example, inflatable kayak floors.

The D7 is available in grey or black and the caps are available in grey, black, and white or yellow. Subject to a minimum quantity and tooling charge, your company logo can be added to the Valve Cap.

Leafield Marine has introduced a specialist high pressure version of the D7 valve – designed and manufactured for drop-stitch applications.   It has an internal mesh that keeps drop-stitch threads-away from the valve seal during installation of the valve.  The internal mesh filter is designed to stop drop-stitch threads and debris from entering the valve seal and causing leaks.  The seal has been designed to operate reliably at the high pressures required with drop-stitch fabric. - Please contact us for more information.
