Pumpensicherheitsblock DBAW40BF1N1X/150S6EG24N9K4R12E - Bosch Rexroth R901008844

Pressure limitation and electrical unloading sit behind the same flange connection in this block. The limiting pressure is entered on the rotary knob between 3.7 and 150 bar, and up to 500 l/min drain to tank once the value is reached.

Benefits

• Rotary knob for the adjustment range of 3.7 to 150 bar
• Flow of up to 500 l/min in size 40 at a maximum operating pressure of 350 bar
• Two functions in one housing, so separate valves and piping are not needed
• Electrical unloading at 24 VDC through a 3-pole connector (2 + PE) according to EN 175301-803
• Pilot-operated pressure valve in poppet seat design, flange connection with two ports
• NBR seals for HL hydraulic fluid, CE conformity, weight of 14.1 kg

Applications

The block suits standard power units of machine tools, clamping systems and test rigs. When an older valve package is replaced, the combined design shortens the assembly work. The rotary knob stays reachable for later adjustment.
