Pumpensicherheitsblock DBAW30BH2-2X/270ZZ6EG24N9K4A08E - Bosch Rexroth R901525683

If a pump keeps delivering against the set pressure during a break, the whole drive power ends up as heat in the tank. The DBAW30BH2-2X/270ZZ6EG24N9K4A08E pump safety block in size 32 limits pressure to 6 to 270 bar and puts the pump into unloaded circulation through solenoid unloading.

Benefits

• Pressure adjustment range 6 to 270 bar at a maximum operating pressure of 350 bar.
• Solenoid unloading through a built-on directional spool valve, 24 VDC, two switching positions, symbol B.
• High-pressure flange with two ports for up to 300 l/min.
• Pilot-operated pressure valve in poppet seat design with an internal hexagon under a protective cap.
• NBR seals for HL hydraulic fluid, connector 3-pole (2 + PE) according to EN 175301-803.
• 3.6 kg mass, CE conformity.

Applications

The block sits at the pump outlet of power units in presses, injection moulding machines and machine tools. During cycle pauses the drive stays in circulation instead of working against 270 bar. That keeps oil temperature down and extends fluid service life.
