B7 Inflation / Deflation Valve

  • Smooth, snag-free profile.
  • Concealed retaining strap.
  • Large cap gives excellent grip in cold conditions.
  • Rugged.
  • Requires no routine maintenance.
  • Clamps into the fabric.
  • Easy inflation due to low back pressure.

Inflation is via a bellows end fitting which is a push-fit into the valve.

To start deflation push down the white central spindle and give it a quarter turn
anti-clockwise to lock the valve open. Turning the spindle clockwise returns the diaphragm to its seat and seals the valve.

The B7 Valve is sometimes used instead of the newer C7, where operation at very low temperatures is required or where the valve needs to seal against the inside surface of the fabric.

Available in black or grey.
