The RSV-1 is a modular control valve that allows a diver to switch breathing gas supplies in less than a second. The RSV-1 is particularly useful to a diver utilizing a full-face mask because it allows the diver to switch to their alternate air supply without discarding their mask (a valuable feature when diving in toxic or hazardous locations).

5 Minutes to Safety
The RSV-1 takes less than 5 minutes to install. Simply remove the supply hose to your regulator and install the RSV-1 in-line. The connection to your alternate supply can be achieved by either a "Quick Disconnect" or a threaded fitting.

Just One Quick Press
 With the button down, the RSV-1 is on Primary gas. Release the safety clip and press the button on the bottom of the RSV-1 and you are on your alternate supply (which is indicated by the brightly colored marker band at the top of the RSV-1).

Simplicity Strikes Again
With only one moving part, maintenance is easy. Simply freshwater rinse the RSV-1 along with your other dive gear. Dry the RSV-1 and remove only one screw in order to disassemble and grease the "O"-rings.

Flexibility
The RSV-1 is made from Delrin® (a high tech engineering plastic from DuPont). The fittings are made from stainless and all "O"-rings are Viton®. The three connection ports are identical, which allows the RSV-1 to be configured to suit the dive mission. Adapters currently available for: Ocean Reef full-face mask, AGA mask, EXO® mask, and most standard regulators with a 9/16-18 thread and also Poseidon® Regulators (special order). Quick disconnect fittings include: AGA, Air Source, and Air 2 fittings. Harness mount and customized fittings are available.

The RSV-1 is intended for use by Rescue, Military, Technical and Commercial Divers
