Leafield Marine D7 inflate deflate valve - the latest model in the ever reliable Leafield Marine valve range.
The D7 has the highest flow rate of all of Leafield's inflation valves, reducing deflation time but with Leafield's renowned engineering. Similar to the C7 with the proven cup diaphragm mounted on a spring loaded spindle. The professionals choice! The rugged cap retaining strap is hidden from view when the cap fitted to prevent it snagging on other equipment. The seal is designed so that it wipes the seal surface as it operates; this reduces leakage due to dirt contamination.
The D7 valve is available in grey or black and also available as a high pressure version (up to 20psi) for air deck, inflatable SUP and other high pressure drop stitch applications - see link below
