Pumpensicherheitsblock DBAW40BH1N1X/315S6EG24N9K4R12E - Bosch Rexroth R901338187

The rotary knob allows the limiting pressure to be changed across the whole band from 3.7 to 315 bar without a tool. The pilot-operated pressure valve in poppet seat design holds the chosen value, and the built-on directional spool valve unloads the pump at 24 VDC.

Benefits

• Adjustment range of 3.7 to 315 bar on the rotary knob, for setup and commissioning without a tool
• Maximum operating pressure of 350 bar with a flow of up to 500 l/min in size 40
• Electrical unloading through the built-on directional spool at 24 VDC
• Poppet seat design of the pressure valve, so the seat closes cleanly once the target is reached
• High-pressure flange connection with two ports
• NBR seals for HL hydraulic fluid, CE conformity, weight of 13.9 kg

Applications

The block belongs on test rigs, experimental power units and machines whose working pressure is settled during trials. Because the band reaches 315 bar, one block covers many pressure levels. After setting, the knob stays reachable for later adjustment.
