Flow Control and Pressure Reducing Automatic Metering Valve (AMV)

The BERMAD Model IR-972-D0-KV integrates a vertical turbine Woltman-type water meter with a diaphragm actuated hydraulic control valve. Equipped with a Mechanical Shut-Off Pilot, a Flow Control Pilot, and a Pressure Reducing Pilot, the BERMAD AMV limits demand and reduces downstream pressure to constant preset maximum values. It automatically shuts itself after accurately delivering a preset quantity of water.
