Highest flow Control Zone Kit on the market for large, commercial drip zones 15.0 to 40.0 gpm (56.8 to 151.4 l/m)
Includes two Pressure Regulating, Quick-Check Basket Filters that have a clear indicator which goes from green to red, telling you when to clean the filters. This reduces maintenance and takes the guesswork out of cleaning the filter. In addition, the threaded top makes it easy to remove and clean the stainless steel screens.

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.
| Minimum Inlet Pressure for 40 psi Outlet Pressure | |
| Flow (gpm) | Inlet pressure (psi) |
| 15.0 | 40.0 |
| 20.0 | 49.0 |
| 25.0 | 50.2 |
| 30.0 | 53.5 |
| 35.0 | 56.1 |
| 40.0 | 60.7 |
