Automatic Metering Valve (AMV) for Sequential Irrigation

The BERMAD Automatic Metering Valve for Sequential Irrigation integrates a vertical turbine Woltman-type water meter with a diaphragm actuated hydraulic control valve, equipped with a Mechanical Sequential Shut-Off Pilot, the BERMAD IR-900-DD automatically shuts itself after accurately delivering a preset quantity of water. Working in a group of manually preset AMV's connected to each other by a control tube and operating in sequence, it enables semi-automatic irrigation in non-computerized systems.
