Bermad IR-970-MO-KVZ Flow Control Valve



Bermad IR-970-MO-KVZ Flow Control Valve

The BERMAD Model IR-970-M0-KVZ integrates a vertical turbine Woltman-type water meter with a diaphragm actuated hydraulic control valve. Serving as Flow Meter and Main Valve, it controls irrigation together with the irrigation controller.

The BERMAD Hydrometer limits the flow to a constant preset maximum. An optional configuration on the valve is to have a battery powered electronic register, which displays both totalising flow and instant rate of flow.
