4.3.5 Pressure regulating valve
A pressure regulating valve (1) protects the
entire lubrication system against excessive sy-
stem pressure. It is mounted directly on the
pump element (2). The cracking pressure set
for this valve is 300 bar or 200 bar, depending
on the valve design. If a blocked feeder or a lu-
brication point causes operating pressure to
rise above 300 (200) bar, the valve opens, fol-
lowed by a noticeable discharge of grease (3).
This also serves as a form of visual system
monitoring.
This protects the pump unit against damage.
A further option are pressure regulating valves
with an emergency lubricant nipple. These can
be used with manual grease presses to provide
the lubrication system with adequate lubricant
in case of power failure or a defective pump.
