OVERPRESSURE VALVE

OVERPRESSURE VALVE Large with bayonet fitting for Sidemount units

The Ovepressure valve has adjustable release pressure by rotation. When used with sidemount unit it does not require pulling any cords to release the pressure from the counterlung.

IMPORTANT INFORMATION:

If the sidemount unit was previously used with the low-profile membrane OPV the bayonet locking mechanism in the counterlung must be replaced by the bayonet connection in this set to safely secure the Overpressure valve in the counterlung.

Otherwise, there is a risk of unlocking the OPV in the bayonet connection when operating the OPV and subsequent flooding of the unit.
