Readable scale
The transparent body shows the setting – set pressure without gauges.
Water-stop install
Disengage the plug and the valve can be serviced without draining the line.
Dust-proof cap
The adjuster is protected against grit and moisture.
Anti-tamper option
The cap locks the setting on public sites.
Frequently asked questions
Where should the regulator be installed?
Directly below the solenoid valve (or inline upstream of nozzles). The catalog notes inlet must be ≥1.0 bar above the target outlet pressure.
Does the PR20 reduce pressure at zero flow?
It regulates while flowing; check static performance in the catalog pressure tables for your setting.
