From a simple load sensing directional valve to an advanced electro hydraulic controlled load independent proportional valve the PVG 100 modular system makes it possible to build up a valve group to fulfill customer requirements. The compact external dimensions of the valve remain unchanged whatever combination is specified.

PVG 100 Proportional Valve Group PVG 100 function PVG 100 with open center PVPF When the pump is started and the main spools in the individual basic modules are in the neutral position, oil flows from the pump, through connection P, across the pressure matching spool (11) to tank. The oil flow led across the pressure matching spool determines the pump pressure (stand-by pressure).

PVG 100 Proportional Valve Group PVG 100 function PVG 100 with closed center PVPV / PVPVP / PVPVM In load sensing systems the load pressure is led to the pump control via the LS connection (2 in the diagram below). When the work functions are in the spring neutral position the LS pressure is drained to tank via the PVG valve.
All PVG 100 modules contain an integrated T0 drain system to insure optimal performance for PVBZ and all electrical actuation offerings. T0 is most effective when connected directly to the hydraulic system reservoir independent of the main Tank return system.

• Wood chippers PVG 100 main spool with pressure compensated control The PC control maintains constant system pressure in the hydraulic circuit by varying the output flow of the pump. Used with a closed center control valve, the pump remains in high pressure standby mode at the PC setting with zero flow until the function is actuated.

Technical Information PVG 100 Proportional Valve Group Technical characteristics The characteristics in this catalog are typical measured results. During measuring a mineral based hydraulic oil with a viscosity of 21 mm /s [102 SUS] at a temperature of 50°C [122°F] was used.
Technical characteristics Caution Because of flow forces, cylinder differential areas, Danfoss recommends Ls margins under 25 bar [360 psi]. As noted above, work port flow is dependent upon the Ls margin set on the pump. PC pumps maintain a constant discharge pressure which is equal to the PC setting on the pump. Hence the Ls margin for PC pumps can be thought of as the difference between the PC setting and the load pressure.

Non-flammable fluids Phosphate-esters (HFDR fluids) can be used without special precautions. However, dynamic seals must be replaced with FPM (Viton) seals.

The following fluids should only be used according to agreement with the Sales Organization for Danfoss: •...
Pressure filters must be fitted to suit max. pump oil flow. Internal filters The filters built into PVG 100 are not intended to filter the system but to protect important components against large particles. Such particles can appear in the system as a result of pump damage, hose fracture, use of quick-couplings, filter damage, starting up, contamination, etc.
PV cover (PVH, PVMD, PVMR, PVMF or PVHC) would be on the “A” port side of the valve. The PVBS in PVG 100 are not symmetric. Because of this the “Load Sense” (Ls) holes in the PVBS main spool must be installed so that they are on the “B” port side of the PVB.
