Low Flow Control Zone Kits with PR Filter

Control Zone Components

These reliable kits include the Rain Bird Low Flow Valve, the only valve on the market that can handle flows below 3 GPM without weeping. These PR Filter kits provide on/off control, filtration, and pressure regulation for drip irrigation systems.

RBY-200SSMX 
200 Mesh Stainless Steel
Replacement Screen

 

Three-year trade warranty.

Kit Includes:

  • 1" Low Flow DV Valve
  • 1" to 3/4" reducer
  • 3/4" RBY pressure regulating filter
  • 3/4" easy fit fitting

Operating Range

  • Flow: 0.2 to 5.0 GPM (0.8 to 18.9 l/m)
  • Inlet Pressure: 20 to 150 psi (1.4 to 10.3 bar)
  • Regulated Pressure: 30 psi (2.1 bar)
  • Filtration: 200 mesh (75 micron)

    Note: 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 30 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 30 psi (2.1 bars) of outlet pressure.

Minimum Inlet Pressure for 40 psi Outlet Pressure
Flow (gpm) Inlet pressure (psi)
0.2 42.9
1.0 44.1
3.0 46.9
5.0 48.5

0.8 2.6
3.8 2.7
11.4 2.8
18.9 3.4
