Pumpensicherheitsblock DBAW40BH2N1X/150S6EG24N9K4R12E - Bosch Rexroth R901371177

The pressure valve works in poppet seat design and therefore closes tightly whenever the set limiting pressure is not reached. The range runs from 3.7 to 150 bar, and the maximum operating pressure of the block is 350 bar.

Benefits

• Internal hexagon under a protective cap, so the limiting pressure stays where it was set
• Poppet seat design of the pressure valve, with next to no oil passing while closed
• Adjustment range of 3.7 to 150 bar at a maximum operating pressure of 350 bar
• Electrical unloading through the built-on directional spool valve at 24 VDC
• Up to 500 l/min in size 40 through the high-pressure flange
• NBR seals for HL hydraulic fluid, CE conformity, weight of 13.34 kg

Applications

The block protects the pump in series power units, machine tools and production cells. Because the setting is covered, the limiting pressure survives the service life of the machine. The control system uses the electrical unloading during start-up and idle periods.
