HPRV (60/68)
Pressure Limiter Screens
W
Warning
Pumps with only HPRV valves no longer contain pressure limiter (PL) screens and retainer. To convert the
pumps to use pressure limiter valves, please contact your Danfoss Service Partner. Pumps that have PL
valves without PL screens and retainers are at high risk of contamination and product malfunction.
H1P Base Models with pressure settings option B include PL screens and retainers.
HPRV Repair (060/068)
The high pressure relief and charge check valve assemblies may be removed for cleaning and
replacement of the O-rings. These valves are factory set and are not field adjustable. Refer to the pump
model code for the factory setting when ordering replacements.
