Pressure Reducing and Sustaining Automatic Metering Valve (AMV) IR-923-D0-KX

The BERMAD Model IR-923-D0-KX integrates a vertical turbine Woltman-type water meter with a diaphragm actuated hydraulic control valve. Equipped with a Mechanical Shut-Off Pilot, a Pressure Sustaining Pilot and a Pressure Reducing Pilot, the BERMAD AMV sustains minimum preset upstream (back) pressure and reduces downstream pressure to a constant preset maximum. It automatically shuts itself after accurately delivering a preset quantity of water.
