©
Danfoss | June 2019
The Closed Center PVPVM mid-inlet module with integrated pilot pressure reduction valve (PPRV) is
intended for use with variable displacement pumps in applications where a valve group with electro-
hydraulic or hydraulically controlled work sections is desired.
Using a PVPVM module in a valve group requires a 180° degree rotation of the PVG work sections on one
side.
The Closed Center PVPVM with PPRV features:
•
Optional shock/anti-cavitation valve facility (PVLP)
•
Threaded ports for P/T/LS and M measuring gauge
•
Integrated pilot pressure reducing valve (PPRV) for PVE or PVH/PVHC
