Open/Closed center PVP with PPRV

© Danfoss | December 2018
The Open Center/Closed Center PVP with integrated pilot pressure reduction valve (PPRV) is intended for
use with fixed or variable displacement pumps in applications where the application manufacturer does
not determine the pump type.
The modules allow an easy switch between Open Center and Closed Center configuration by means of an
external hexagon selector key. Variants also feature an LS boost functionality, increasing the LS pressure
to the pump LS regulator with a constant 6 bar, compensating for potential LS bleed-off and leakage.
The Open/closed center PVPV with PPRV features:
•
Integrated OC/CC selector
•
Integrated LS pressure relief valve
•
Threaded ports for P/T/LS and M measuring gauge
•
Integrated pilot pressure reducing valve (PPRV) for PVE or PVH/PVHC
•
Optional LS boost functionality
