Valves

In order to control different spray circuits with a pump, we need valves that direct the pumped and pressurised water into the respective spray circuits. RainCo 3.0 can control up to 6 valves, enabling 6 spray circuits to be implemented.

There are many different suitable valves available from numerous manufacturers! Among others, you can also take a look at MSR - Micro Rain Systems.
The valves used should be suitable for drinking water and for the pressure supplied by the pump. Furthermore, they should be designed for a DC voltage of 24 volts and be closed when de-energised. The valve coil should draw a maximum of 800mA when open.

It is important to ensure that the valves used are designed for 24 V!

I have had very good experiences with valves for osmosis systems. These are inexpensive and can be purchased from Amazon (€14-18) or AliExpress (€5-8), among others. These valves often have a connection for 6mm hoses.
They are available from various suppliers/manufacturers/brands, with or without a 6 mm hose connection and for different voltages. So when purchasing, make sure you buy valves for 24 volts!


I have developed mounting plates for these osmosis valves. One for 4 valves and one for 2 valves. The drilling pattern for the valves I use is 25x25mm (most osmosis valves offered on AliExpress should have this; however, this must be checked).
The STL files for printing yourself are available for download on RainCo.3's Github page.





Here you can see the mounting plate for 4 valves, complete with cables, hoses and electrical distribution board.



This is the carrier board for 2 valves, including the electrical distribution board.
