Pumpensicherheitsblock DBAWR40BH2N1X/310S6EG24N9K4R12E - Bosch Rexroth R901079748

The spring of the pressure valve decides how precisely the cut-off pressure can be hit. The DBAWR40 with a range of 3.7 to 310 bar limits system pressure inside that window and lets 600 l/min through the size 40 high-pressure flange.

Benefits

• Pressure setting range 3.7 to 310 bar at the internal hexagon with protective cap
• 600 l/min flow, maximum operating pressure 350 bar
• Electrical pump unloading through a built-on directional spool valve at 24 VDC
• Pilot-operated pressure valve in poppet seat design with two switching positions
• Size 40 high-pressure flange, two ports, CE conformity
• NBR seals for HL hydraulic fluid, 14.7 kg weight

Applications

The block goes on power units that work continuously near 300 bar and still need headroom to the permitted operating pressure. At start-up the pump stays pressureless through the solenoid. The poppet seat design gives a tight shut-off at rest.
