Pressure Reducing
Automatic Metering Valve (AMV)

The BERMAD Pressure Reducing Automatic Metering Valve integrates a vertical turbine Woltman-type water meter, with a diaphragm actuated hydraulic control valve. Equipped with a Shut-Off Pilot and a Pressure Reducing Pilot, the BERMAD IR-920-D2-R reduces higher upstream pressure to lower constant downstream pressure. It automatically shuts itself after accurately delivering a preset quantity of water.
