First Stage Over-Pressure Valve (OPV)

An over-pressure valve for scuba regulator first stages. It provides a relief path for excess intermediate pressure, helping protect hoses and downstream components.

• For use on regulator first stages
• Vents excess pressure if it rises above a safe threshold
• Useful when a first stage may be pressurized without a second stage attached

Installation and service should be performed by a qualified technician.
