Pumpensicherheitsblock DBAWR40BH2N1X/315-6EG24N9K4V - Bosch Rexroth R900784743

The larger the power unit, the more flow the protection has to discharge in an emergency. The pilot-operated pump safety block DBAWR40BH2N1X/315-6EG24N9K4V is designed for this in size 40 and carries up to 450 l/min at a maximum operating pressure of 350 bar.

Benefits

• Up to 450 l/min in size 40, designed for power units with large pumps.
• Pressure adjustment range 3.7 to 315 bar, so the circuit can be tuned closely to working pressure.
• Pressure valve in poppet seat design stays tight when closed, unlike a spool solution with gap leakage.
• High-pressure flange connection for a short, low-loss link to the pump.
• Solenoid unloading at 24 VDC across two switching positions to symbol B.
• FKM seals at a block weight of 13.86 kg, HL hydraulic fluid.

Technical data

Applications

The block belongs at the outlet of powerful units, for example on hydraulic presses, casting plants and large test rigs. The poppet seat design also pays off when the plant stands under pressure for long periods and no leakage may occur. Control runs through a 3-pole connector (2 + PE) to EN 175301-803.
