Pressure Reducing and Sustaining
Automatic Metering Valve (AMV)

The BERMAD Mddel IR-923-D2-R integrates a vertical turbine Woltman-type water meter with a diaphragm actuated hydraulic control valve. The BERMAD AMV performs three independent functions. It sustains the preset minimum upstream pressure; it reduces downstream pressure to a constant preset maximum, and it automatically shuts itself after accurately delivering a preset quantity of water.
