Pumpensicherheitsblock DBAW15BH2-2X/330-6EG24N9K4E - Bosch Rexroth R901257866

At start-up the full pump pressure is present long before the machine needs it. This block unloads the pump through a built-on directional spool valve and then limits pressure within the 6 to 330 bar range, at flow up to 250 l/min.

Benefits

• Setting range 6 to 330 bar on a pilot-operated pressure valve of poppet seat design, maximum operating pressure 350 bar.
• Flow up to 250 l/min in size 16, rated for HL hydraulic fluid.
• Electrical unloading at 24 VDC through the built-on directional spool valve with 2 switching positions.
• High-pressure flange to connection diagram ISO 4401-03-02-0-05 with 2 ports.
• 6.04 kg weight with NBR seals and a 3-pole connector (2 + PE) to EN 175301-803.
• Internal hexagon with protective cap for the pressure setting, CE conformity.

Application

The block belongs at the pump outlet of power units that start and stop frequently. The poppet seat design of the pressure section keeps leakage low while pressure is held. Spool symbol B defines how the unloading stage switches. Between the 330 bar setting stage and the 350 bar maximum operating pressure there is headroom.
