The unbalanced model (EX 2776) is a simpler design, without the internal one way valve. This basic design means fewer parts to maintain and clean.
The Unbalanced Relief Valve has a hands-free design with an external one way valve so that the relief valve can be dived without being connected. Prime the tube before descending for a worry-free, comfortable dive. It is very important to clean your relief valve after use to prevent urinary infections. Steramine is popular for cleaning relief valves and rebreather breathing loops.
Made in the USA.
Note: Installation requires a standard 5/8 inch punch, Dive Rite model no EX2786TOOL. We recommend installation by a professional drysuit repair center.
