The Control Zone Kit includes all the components you need to set up a low volume drip irrigation zone in minutes. It includes a valve for automatic operation and components for filtration and pressure regulation, already preassembled and ready to connect to an irrigation controller. The compact design fits easily inside a standard valve box. This kit is engineered for a maximum flow rate of 5 GPM. The pressure-regulating filter maintains 30 PSI and has a 200-mesh stainless steel filter screen to block particulates in the water from entering the drip system.
