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).
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.
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
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.
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.
