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

Technical data

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.
