PRESSURE REGULATOR PR3
The PR3 pressure regulator is designed for a precise regulation of the operating pressure to 0-12 bar.
The basic version of the PR3 C regulator consists of a central control valve with an integrated vacuum
anti-drip system and diverter valves.
In addition to diverter valves, the upgraded version of the PR3 B also features integrated directional
control valves to provide for a precise adjustment of the operating pressure in each section of the spray
boom.
The basic equipment of the pressure regulator also includes a self-cleaning pressure filter.
9.1.1
REGULATOR MARKING
If the pressure regulator is equipped with a self-cleaning pressure filter, the basic marking of PR3 C or
PR3 B includes the letter F. The number of directional control valves and diverter valves is indicated
with a number code (the first number indicates the directional control valves and the second indicates
the diverter valves).
Example:
The marking PR3 BF/5+1 indicates the regulator PR3 B with self-cleaning pressure filter, five
directional control valve valves and one diversion valve.
