Open center PVP with HPCO and PVE PPRV
The Open Center PVP inlet with integrated High Pressure Carry Over (HPCO) functionality is intended for
use with fixed displacement pumps in applications where one pump supply for multiple hydraulic
subsystems is desired.
The integrated HPCO functionality guides the excess flow of the PVG 16 valve group to the external
hydraulic subsystem(s), giving priority to the PVG 16 work functions.
The Open Center PVP with HPCO and PVE PPRV features:
•
Integrated LS pressure relief valve
•
Threaded ports for P/T/LS/HPCO and M measuring gauge
•
Integrated pilot pressure reducing valve (PPRV) for PVE
•
Optional T0 facility and external T0 port
•
Optional external pilot pressure port (Pp)
•
Optional LS unloading valve, PVPX
Only applicable with PVST end plates with separate T-port due to blocked T-lines for HPCO functionality.
