Pumpensicherheitsblock DBAW40BF1N1X/100S6EG24N9K4R12E - Bosch Rexroth R901049929

The rotary knob sets the limiting pressure between 3.7 and 100 bar, and the pilot-operated seat valve holds it in operation. The flange connection places the block directly in the pressure line of the pump, while the built-on directional spool valve unloads at 24 VDC.

Benefits

• Adjustment range of 3.7 to 100 bar, matched to clamping and tooling circuits
• Flow of up to 500 l/min in size 40 at a maximum operating pressure of 350 bar
• Rotary knob, so the target value can be trimmed without a tool
• Electrical unloading through the built-on directional spool at 24 VDC
• Flange connection with two ports, pressure valve in poppet seat design
• NBR seals for HL hydraulic fluid, CE conformity, weight of 14.55 kg

Applications

The block is used on the power units of clamping systems, plastics machinery and assembly plant. A range to 100 bar covers the working pressures common there without calling for a valve rated across the full band. Electrical unloading keeps the circuit free of pressure during pauses.
