Pumpensicherheitsblock DBAW40BF1N1X/125S6EG24N9K4R12E - Bosch Rexroth R901044038

The 125 bar rating closes the gap between the two common designs. The rotary knob sets the limiting pressure between 3.7 and 125 bar, the block lets up to 500 l/min drain to tank and unloads the pump electrically at 24 VDC.

Benefits

• Adjustment range of 3.7 to 125 bar on the rotary knob
• Flow of up to 500 l/min in size 40 at a maximum operating pressure of 350 bar
• Pressure limitation and electrical unloading in one block
• Pilot-operated pressure valve in poppet seat design
• Flange connection with two ports, solenoid actuation at 24 VDC through a 3-pole connector (2 + PE) according to EN 175301-803
• NBR seals for HL hydraulic fluid, CE conformity, weight of 14.3 kg

Applications

The block protects the power units of presses, stamping machines and production cells of medium power. Because the adjustment range ends at 125 bar, the target value is easy to hit within that band. While the plant stands, the control system leaves the circuit without pressure through the solenoid.
