Pressure Reducing and Sustaining Hydrometer Model 923-MV

The BERMAD Model WW-923-MV integrates a vertical turbine Woltman-type water meter with a diaphragm actuated hydraulic control valve.

The WW-923-MV sustains the preset minimum upstream pressure and reduces higher upstream pressure to lower constant downstream pressure, regardless of varying demand or upstream pressure.
