Pumpensicherheitsblock DBAW30BH2-2X/150-6EG24N9K4A08VE - Bosch Rexroth R901554519

A pump circuit has to be protected against excess pressure and unloaded electrically for start-up. The DBAW30BH2-2X/150-6EG24N9K4A08VE pump safety block covers both in one unit, the pilot-operated pressure valve in poppet seat design limits to the setting within a range of 6 to 150 bar, while the built-on directional spool valve unloads through the solenoid. In size 32 it carries up to 300 l/min at a maximum operating pressure of 350 bar.

Benefits

• Pilot-operated pressure limitation in poppet seat design, setting range 6 to 150 bar
• Maximum operating pressure 350 bar as the design limit of the pump circuit
• Flow up to 300 l/min in size 32
• Solenoid unloading at 24 VDC, connector 3-pole (2 + PE) according to EN 175301-803
• High-pressure flange connection, 2 ports, spool symbol B with 2 switching positions
• FKM seals for hydraulic fluid HL, weight 1.5 kg, CE conformity

Applications

The block is mounted directly at the pump outlet of power units running a fixed displacement pump that should circulate unloaded during start-up. Sizing follows the required system pressure inside the 6 to 150 bar setting range, the pump delivery of up to 300 l/min and the high-pressure flange interface. Pressure is set through an internal hexagon with protective cap, and the FKM seals define compatibility with hydraulic fluid HL.
