Internal Filters - Danfoss PVG 100 Technical Information

Technical Information
Other operating conditions
PVG 100 Proportional Valve Group
The fineness of a pressure filter must be selected as described by the filter manufacturer so that a particle
level of 23/19/16 is not exceeded.
The filter must be fitted with pressure gauge or dirt indicator to make it possible to check the condition of
the filter.
In systems with differential cylinders or accumulators the return filter must be sized to suit the max.
return oil flow. Pressure filters must be fitted to suit max. pump oil flow.

Internal filters

The filters built into PVG 100 are not intended to filter the system but to protect important components
against large particles. Such particles can appear in the system as a result of pump damage, hose fracture,
use of quick-couplings, filter damage, starting up, contamination, etc.
The filter in the electrical actuator PVE protecting the solenoid valves has a mesh of 150 µm.
Bursting pressure drop for internal filters is 25 bar [360 psi].
