The generic PVP inlet module accessory platform includes the PVPX Electrical LS pressure unloadingvalve, External pilot pressure adapters PVPC with or without check valve for all Open Center PVP withPPRV.• PVPX Electrical LS Pressure Unloading Valve on page 33• PVPC without Check Valve on page 36• PVPC with Check Valve on page 37PVPX Electrical LS Pressure Unloading ValveThe electrical LS pressure unloading valve is an accessory available for PVP inlet modules with PVPXfacility. The PVPX consist of a solenoid valve and a magnetic coil package, allowing the operator to relievethe LS pressure to tank electrically.Configuration variants also feature a Manual Override functionality to activate the PVPX manually:• Normally Open (NO),• Normally Open with Manual Override (NOMO)There are two types of NOMO-configurations - PUSH, and PUSH & TURN. With the TURN function you cankeep the override function until you unlock it again.• Normally Closed (NC)Configuration variantsNormally Open (NO) Normally Open with MOR (NOMO) Normally Closed (NC)Relieving the LS pressure to tank results in a reduced system pressure level, which is determined by:• the sum of the tank and neutral by-pass pressure drop in a Open Center PVP configuration• the sum of the tank and standby-pressure in a Closed Center PVP configurationPVPX with NOMO schematicPTMLSPVPX technical dataVoltage supply 12/24 VDC ± 10%Resistance @ 12 VDC 7.2 Ω ± 7%Resistance @ 24 VDC 28.2 Ω ± 7%Power consumption 20 WMaximum LS response time 300 msMax. pressure drop @ 0.1 l/min [2.6 US gal/min] 2 bar [30 psi]Technical InformationPVG 16 Proportional Valve GroupPVP Inlet Module Accessories© Danfoss | December 2018 BC00000211en-000901 | 33
