Fluid
Prior to venture style, make sure you see our data sheets RE 95710 (mineral oil ) and RE 95711 (ecologically suitable fluids) for comprehensive details on fluids and application conditions. When employing ecologically acceptable fluids focus must be compensated to attainable limits of the technological knowledge.
Notes on the choice of hydraulic fluid
In purchase to select the right fluid, it is essential to know the working temperature in the tank (open circuit) in relation to the ambient temperature. The hydraulic fluid ought to be picked so that inside of the working temperature assortment, the viscosity lies within the the best possible variety (νopt.) see shaded area of the selection diagram. We advocate that the higher viscosity grade is selected in every circumstance. Instance: at an ambient temperature of X°C the running temperature in the tank is 60 °C. In the the best possible viscosity range νopt (shaded location), this corresponds to viscosity grades VG forty six or VG 68, VG 68 need to be selected. Essential: The leakage oil  temperature is influenced by force and pace and is normally increased than the tank temperature. However max. temperature at any point in the method may possibly not exceed a hundred and fifteen °C. At large temperatures remember to use FKM seals.
DG – two stage, direct management
The pump can be established to a minimum swivel angle by connecting an exterior switching force to port X. This will source the manage piston right with control oil a minimal stress of 50 bar is required.
DR – Strain control 
The stress control serves to keep a continual strain in the hydraulic program, in the manage assortment of the pump. The pump therefore provides only the quantity of hydraulic fluid required by the actuators. Strain can be steplessly established at the pilot valve.
DRG – Pressure management, remote  
A pressure aid valve may possibly be externally piped to port X for remote handle reasons. However it is not integrated in the scope of supply with the DRG manage. The differential pressure at the DRG manage spool is set as normal to twenty bar and this outcomes in a pilot circulation of one,five L/min. If another placing is needed, you should state this in obvious textual content.
DFR/DFR1-Force-flow control  
In addition to the pressure handle operate, the pump movement to the actuator could be assorted by implies of a differential strain (eg. in excess of an orifice or directional management valve). The pump materials only the quantity of fluid as required by the actuator. In the DFR1-valve
DFLR – Pressure/stream/power control   
In get to achieve a consistent generate torque with a varying running strain, the swivel angle and with it the output flow from the axial piston device is different so that the merchandise of circulation and stress continues to be continuous.
FHD – Displacement management, pilot stress dependent, with force control   
The swivel angle of the pump, and consequently the displacement or movement, is dependent on the pilot pressure pSt X in port X.
 
A constant pressure py = 35 bar is required at port Y. An overriding force control is built-in, and can be sleeplessly established at the control valve.
