Pumpensicherheitsblock DBAWR40BH2N1X/315S6EG24N9K4R12E - Bosch Rexroth R901396943

On a power unit a pump safety block covers two jobs at once, pressure limitation and pump unloading. The DBAWR40 in this version covers a setting range of 3.7 to 315 bar and handles 600 l/min at a maximum operating pressure of 350 bar.

Benefits

• Pressure setting range 3.7 to 315 bar through an internal hexagon with protective cap
• 600 l/min flow, maximum operating pressure 350 bar
• Electrical unloading through a built-on directional spool valve at 24 VDC
• Pressure valve in poppet seat design, pilot-operated, two switching positions
• High-pressure flange connection in size 40, two ports
• NBR seals for HL hydraulic fluid, CE conformity, 14.52 kg

Applications

The block sits directly at the pump outlet of power units in presses, test rigs and steelworks equipment. During start-up the pump is run pressureless through the solenoid, which cuts the breakaway torque of the motor. The poppet seat design keeps leakage low in the closed state.
