Pressure Sustaining Automatic Metering Valve (AMV)

The BERMAD Model IR-930-D2-R integrates a vertical turbine Woltman-type water meter with a diaphragm actuated hydraulic control valve. Equipped with a Mechanical Shut-Off Pilot and a Pressure Sustaining Pilot, the BERMAD AMV sustains minimum preset upstream (back) pressure. It automatically shuts itself after accurately delivering a preset quantity of water.
