Netafim Arad DOSE-O-MAT K Automatic NC Volume Based Timer Metering Valve (Shut of Valve)

Precise, water-saving metering valve for volume-controlled irrigation.

The Netafim DOSE-O-MAT K (by Arad) is a fully integrated, automatic metering valve that combines a volumetric water meter, volume control dial, and double-chamber valve in one compact, efficient unit. Designed for precision irrigation and batching applications, it opens to deliver a pre-set water volume and automatically shuts off when the exact volume has been dispensed.

This system delivers improved irrigation control with up to 30% water savings compared to time-based systems, making it ideal for farms, nurseries, and small-scale irrigation zones.

Arad Dose-O-Mat is an automatic metering valve comprising a water meter, a volume control Dial and a valve in a single body. The device is normally closed. Upon setting the required volume on the Dial the internal valve opens, the set volume is delivered and then the valve shuts down automatically.
