Technical Remarks
■	The pressure dew point must be at least 15 °C under ambient and medium temperature and may not exceed 3 °C.
■	The oil content of air pressure must remain constant during the life cycle.
■	Use only the approved oils from Bosch Rexroth, see chapter „Technical information“.

1) Pilot: internal
2) Pilot: external
3) with throttle
Differential piston, signal 14 has priority
The minimum pilot pressure at port 14 is dependent on the pressure in port 1.
Nominal flow Qn at 6 bar and Δp = 1 bar
