6.1.2 Pressure regulating valve
A pressure regulating valve can be installed on
the pump element on progressive systems to
prevent excessive operating pressure in the
lubrication system. If the operating pressure
exceeds the cracking pressure of the pressure
regulating valve (see Technical Data,
Chapter4.3.4 in the assembly instructions), the
valve opens and the lubricant flows back (on
versions with a return line) into the lubricant
reservoir.
