Rescue Drysuit Dump Valve - Supplier
We use a dump valve from the Swedish manufacturer SI-TECH® for installation in the cuff area of a rescue drysuit, where the user lifts his arm to expel air from the rescue drysuit. The dump valve is not a substitute for the exhaust valve, and should be used in conjunction with the exhaust valve. Non diving drysuits can be used alone (eg rescue drysuits).
