Filtration systems rely on pressure for efficiency. Your cartridge life is reduced every time depressurisation occurs, so Midland Diving introduced the Pressure Maintaining Valve.
Our PMV series hold a set level of pressure in a filter system, to maximise cartridge life and ensure efficient air filtration.
All models are supplied with 1/4BSPTM inlet and 1/4BSPPM cone outlet for metal to metal seal with a charging hose, and can optionally be factory set, wire-locked and tagged for a small charge
