Pumpensicherheitsblock DBAW30BH1N1X/170-6EG24NK4E - Bosch Rexroth R901348010

A pump delivering into a closed circuit destroys itself or the line. The pump safety block DBAW30BH1N1X/170-6EG24NK4E limits pressure in poppet seat design to a value set between 3.7 and 170 bar and additionally unloads the pump electrically, at a flow of up to 360 l/min.

Benefits

• Pressure adjustment range 3.7 to 170 bar, set with a rotary knob on the valve.
• Solenoid unloading through a built-on directional spool valve, the pump can start unpressurised and stay unloaded at standstill.
• Pressure valve in poppet seat design, pilot-operated, for a maximum operating pressure of 350 bar.
• Up to 360 l/min across two ports in two switching positions, size 32.
• High-pressure flange connection, laid out for direct mounting on the power unit.
• 9.2 kg, actuation at 24 VDC, NBR seals for HL hydraulic fluid, CE conformity.

Applications

The block sits directly at the pump outlet of power units in presses, clamping systems and test rigs, where it performs two jobs in one housing. It limits system pressure to the set value and switches delivery to unpressurised circulation as soon as the controller de-energises the solenoid. That relieves the drive during start-up and keeps the oil cooler during pauses.
