Enabling Efficiency in Filtration更有效过滤压力阀

　　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￡3.40 charge (please quote code ZWL and your requested setting when ordering).
