Rain Bird X13001 PRF100RBY 1" Pressure-Regulating Filter (RBY) a unique, compact unit that combines filtration and pressure regulation in one piece for protection of downstream components in a low-volume irrigation system. Reduces the number of components in a control zone, making it smaller and easier to install. More control zones can fit in one valve box!

Combination unit reduces the number of connections, making installation easier and faster. Increased reliability - fewer parts and fewer threaded connections mean less chance of a leak both at installation and over the life of the system.
