Dry Valve Technology Regulators (DVT)

Dry Valve Technology DVT is a revolutionary regulator technology designed to automatically eliminate moisture and contaminants from entering your first stage, even if the dust cap is accidentally left off. DVT eliminates corrosion of critical internal components, bacteria, hose deterioration, and damaged gauges and computers.

Most dust caps are not designed to keep water from entering your first stage. Regardless of how carefully you may maintain your regulator, water entry is a much more common problem than most divers realize.

When water enters your first stage, critical internal seals break down and precision-machined metal parts begin to corrode. This inevitably leads to significant performance degradation and expensive repairs. Moisture also spreads throughout your breathing system, causing bacteria build-up, hose deterioration, and damage to gauges and computers. This can be eliminated with the use of DVT

DVT works so that when you open the tank valve and air is delivered through a downstream system without restriction. When your dive is finished, before the regulator is even removed from the tank valve, the Dry Valve Technology (DVT) system is already closed, sealing out moisture and any other contamination. The filter is safely positioned behind the moisture barrier to eliminate filter flow restriction due to corrosion.

DVT will significantly improve the long tem performance of your regulator, improving your air consuption and diving enjoyment.
