Pressure Sustaining Automatic Metering Valve (AMV) IR-930-DO-KX

The BERMAD Pressure Sustaining 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 Sustaining Pilot, the BERMAD Model IR-930-D0-KX sustains minimum preset upstream (back) pressure and opens fully when line pressure is in excess of setting. It automatically shuts itself after accurately delivering a preset quantity of water.
