IR-920-D0-bK

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 Mechanical Shut-Off Pilot and a Pressure Reducing Servo Pilot, the BERMAD IR-920-D0-bK accurately reduces higher upstream pressure to very low and stable preset downstream pressure. It automatically shuts itself off after precise delivery of a preset quantity of water.
