Closed Center PVP with PPRV
The Closed Center PVP inlet 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.
The Closed Center PVP with PPRV features:
•
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
