Rain Bird X10332 XCZPGA100PRF Medium Flow Control Zone Kit with 1" PGA Valve and 1" PR Filter, these PR Filter kits provide on/off control, filtration, and pressure regulation with only two parts; so there is less chance of leakage at the connections, both at installation and over the life of the system.

Shorter kits with only two components (valve plus pressure-regulating filter) mean that you can fit more Control Zone Kits in a valve box, saving time and money.
