Pressure reducing valves in car washes? But safe!

We all know them, the practical car wash.

Simply drive the vehicle in, start the programme and a few minutes later it is sparkling clean without any manual effort.

But how do car washes work?

In addition to sophisticated wash brush technology, cleaning with water and foam plays a major role. But how do you ensure the right mixing ratio between water and foam cleaner?


SUCCESSFUL IN USESeries 9000

By using the pressure reducing valves 9000 from Goetze.

This regulates the pressure upstream of the mixing nozzle precisely and thus ensures that not too much water is dosed due to excessive pressure.  

In addition, the integrated filter screen protects the sensitive nozzles from contamination with associated clogging and costly repair.

Corrosion-resistant materials such as gunmetal also play a major role. RG+ offers excellent properties and a long service life in this respect.
