RAIN BIRD XERIGATION CONTROL ZONE KITS:

The Rain Bird XCZ100PRFBF is a 1" pre-assembled kit with in-line valve and automatic Back Flush Filter.

This compact, factory assembled two-piece kit combines the 1" DV Valve with the 1"Pressure Regulating Back Flush Filter to save installation time. The Pressure Regulating Back Flush Filter is a 200 mesh (75 micron) automatic self-cleaning filter that includes a 40 psi (2,8 bars) pressure regulator. The Back Flush Filter should be used in municipal water applications only.

Caution: An in-line check valve is required if the kit is not at the highest point in the irrigation system.

Pressure Loss Chart

In order to supply 40 psi (2,8 bars) outlet pressure, additional pressure is needed at the inlet since there is some pressure loss from water flowing through the kit. The amount of pressure loss depends on the flowrate. The charts below list the minimum inlet pressure required to supply 40 psi (2,8 bars) of outlet pressure.
