Cracking pressure (in free direction)			See characteristic curves
Maximum flow		l/min	300
Direction of flow			see symbols
Hydraulic fluid			see table "Hydraulic fluid"
Hydraulic fluid temperature range (at the valve working ports)	NBR seals	°C	-30 … +80
	FKM seals	°C	-20 … +80
Viscosity range		mm²/s	2.8 … 500
Maximum admissible degree of contamination of the hydraulic fluid, cleanliness class according to ISO 4406 (c) ¹⁾			Class 20/18/15
Area ratio	With pre-opening		A₃/A₂ ~ 1/12 (see sectional drawing)
Area ratio	Version "SO60"		A₁/A₄ ~ 1/7 (see sectional drawing)

¹⁾	The cleanliness classes specified for the components must be adhered to in hydraulic systems. Effective filtration prevents faults and simultaneously increases the life cycle of the components. For the selection of the filters, see www.boschrexroth.com/filter.

Important information on hydraulic fluids: There may be limitations regarding the technical valve data (temperature, pressure range, life cycle, maintenance intervals, etc.). The ignition temperature of the hydraulic fluid used must be 50 K higher than the maximum surface temperature. Flame-resistant - containing water: Maximum pressure differential 210 bar, otherwise, increased cavitation erosion Life cycle as compared to operation with mineral oil HL, HLP 30 … 100%. Maximum hydraulic fluid temperature 60 °C Bio-degradable and flame-resistant – containing water: If this hydraulic fluid is used, small amounts of dissolved zinc may get into the hydraulic system.

¹⁾	Not recommended for corrosion-protected version "J3" (contains zinc)

Notice:

Selection of optimal sealing material (see "Type code") also depends on the type of hydraulic fluid used.
