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 is made from Delrin (a high tech engineering plastic from DuPont). The fittings are made from stainless and all "O"-rings are Viton.

Adapters and quick disconnect fittings currently available (sold separately) for: Ocean Reef full-face mask, AGA mask, EXOmask, and most standard regulators with a 9/16-18 thread and also Poseidon Regulators (special order). 

Can be harness mounted and customized. The RSV-1 is intended for use by Rescue, Military, Technical and Commercial Divers
