Pressure Reducing and Sustaining Hydrometer WW-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. Features and Benefits ■ Integrated "All-in-One" Control Valve □ Saves space, cost and maintenance ■ Line Pressure Driven □ Protects downstream system □ Prioritizes pressure zones □ Controls system fill-up ■ Magnetic Drive with Vacuum-Sealed Register □ Water-free gear train mechanism □ Reed-switch and Opto pulse-generating modes □ Various pulse combinations ■ Internal Inlet & Outlet Flow Straighteners □ No Need for Flow straightening distances □ Maintains accuracy ■ Integrated Flow Metering Calibration Device ■ User-Friendly Design □ Simple in-line inspection and service Available Sizes Control Diagram For engineering specifications refer to the engineering data section, for ordering to the ordering guide, both available at our website www.bermad.com [email protected] • www.bErmad.com © Copyright 2007-2012 Bermad CS Ltd.
