The Northern Diver Commercial Drysuit Exhaust Valve features an extra diaphragm in the design, making it resistant to chemically contaminated waters, and the option of a double mushroom valve which further increases the resistance to ingress. 

Contaminated water valves are designed for heavy use and have increased resistance to chemical contamination, impact and heat. The exhaust valve contains an extra diaphragm compared to a standard drysuit exhaust valve design.

These high performance drysuit exhaust valves have been developed by Northern Diver's  in-house engineering team, with every component carefully quality and cycle tested, in Northern Diver's on-site workshop, which allows maximum control over the quality of every valve produced.

All Northern Diver drysuit exhaust valves have passed the strict testing at TUV-RHEINLAND with a 100% rating and are fully CE approved.

These drysuit exhaust valves are perfect for commercial and military diving applications and are also well suited for recreational drysuit diving.
