Open/Closed center PVP with PPRVThe Open Center/Closed Center PVP with integrated pilot pressure reduction valve (PPRV) is intended foruse with fixed or variable displacement pumps in applications where the application manufacturer doesnot determine the pump type.The modules allow an easy switch between Open Center and Closed Center configuration by means of anexternal hexagon selector key. Variants also feature an LS boost functionality, increasing the LS pressureto 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 functionalityHydraulic schematicLSTPMOC CCTechnical specification for PVPMax.
