The Sonar Low Pressure (LP) Inline Regulator Long Shut-Off Valve fits in-line between your low-pressure regulator hose and your second stage regulator. This valve provides positive tactile feedback when operated. As with any cutoff, the regulator first stage should also have an Over Pressure Valve (OPV) if the shutoff is used to disable the only pressure relief path.
Used to prevent gas loss from dribbling or free flowing from a second stage or rebreather ADV, or whenever the ability to very rapidly stop gas flow is required. Ideal for decompression bottles or stages bottles where preventing gas loss is critical.
The long model works well in colder water conditions where heavier gloves are used. When using 3mm or thicker gloves this shut off valve is an excellent choice.
Regulators not designed for cold water use are especially prone to freezing. This Sonar LP Inline Regulator Long Shut-Off Valve is simple yet extremely effective and contributes a significant advance in diver safety. In the event of 2nd stage freezing, free flow can cause catastrophic loss of air. With the this device fitted to your regulator 2nd stage, a simple sliding action allows you to isolate the free flowing 2nd stage and continue the dive using a secondary air source or alternatively, the diver can manually control the air flow allowing a safe ascent to the surface.
