OPV-Over Pressure Valve Zeagle BCD Dump Valve Complete

In order to ensure the utmost safety during dives, technical divers must equip themselves with redundant safety back-ups for all their equipment. While a well-maintained first-stage regulator should function properly, the addition of safety features is crucial in the event of a malfunction, as it could mean the difference between managing an emergency situation and a full-blown diving accident.

One important safety feature to consider is the incorporation of a safety relief valve on the first-stage regulator. This valve serves to prevent over pressurization of the 2nd-stage hose, reducing the risk of equipment failure and subsequent accidents. The Over-Relief Valve (OPV) is a compact device that releases pressure if the first-stage regulator becomes over pressurized.

The OPV is designed for easy installation into a standard 3/8-24 UNF low-pressure regulator port. Factory set at 175 to 185 psi (12 to 12.75 bars), this valve is constructed from chromed brass with a stainless steel internal spring. By investing in safety features such as the OPV, technical divers can significantly reduce the chances of encountering dangerous situations underwater.
