Pressure Reducing Automatic Metering Valve (AMV) IR-920-DO-KX

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 Mechanic Shut-Off Pilot and a Pressure Reducing Pilot, the BERMAD Model IR-920-D0-KX reduces higher upstream pressure to lower constant downstream pressure and opens fully upon line pressure drop. It automatically shuts itself after accurately delivering a preset quantity of water.
