The SHUT-OFF Valve is a mechanical flow switch designed to ensure immediate and safe control of air passage in low-pressure lines.
Positioned directly between the LP hose coming from the first stage and the second stage regulator, it allows for instant air flow interruption with a simple action. It is the ideal accessory to block accidental continuous flows (free-flow), preventing the rapid loss of the breathable gas supply during a dive.
Key Features:
-
Quick Delrin Actuation: Equipped with a robust Delrin knob (a plastic material with very high mechanical strength and hydrophobic properties), which is activated with a slight lateral movement, ensuring a clean shut-off even when wearing thick or dry gloves.
-
Continuous Flow Prevention: Eliminates the risk of rapid tank depletion in case of second-stage freezing, continuous free-flow on the surface, or internal valve malfunctions.
-
Wide Versatility of Use: Particularly valued in Rebreather (CCR) systems for isolating the loop or manual addition valves (MAV), but widely used in both technical (stage bottles) and recreational diving.
-
Universal LP Compatibility: Equipped with standard 9/16" UNF connections and threads (male and female), compatible with all commercially available second stages and LP hoses.
Safety and Maintenance Advice: The Shut-Off valve is an emergency management tool. It should be thoroughly rinsed with fresh water after each dive to prevent salt or lime buildup in the sliding mechanism, and always ensure it is in the "OPEN" position before entering the water.
