Flow Control
Pressure Reducing
Automatic Metering Valve (AMV)

The BERMAD Model IR-972-D2-RV integrates a vertical turbine Woltman-type water meter with a diaphragm actuated hydraulic control valve. The BERMAD AMV controls system demand to a preset maximum flow rate; reduces downstream pressure to a constant preset maximum, and automatically shuts itself after accurately delivering a preset quantity of water.
