Pumpensicherheitsblock DBAWR40BH2N1X/315S6SMG24N9K4B12E - Bosch Rexroth R901218918

A pump safety block combines pressure limitation and electrical unloading in one body. The DBAWR40BH2N1X/315S6SMG24N9K4B12E accepts up to 600 l/min, limits to 350 bar and switches the unloading function on 24 VDC.

Benefits

• Electrical unloading through a built-on directional seat valve, switched at 24 VDC.
• 600 l/min flow at 350 bar maximum operating pressure in size 40.
• Pilot-operated pressure limitation in poppet seat design, internal hexagon with protective cap.
• High-pressure flange with 2 ports, CE conformity.
• 14.54 kg, NBR seals for HL hydraulic fluid, 3-pole (2 + PE) plug to EN 175301-803.

Applications

The block sits directly at the pump outlet of power units in presses, test rigs and special machinery. During start-up and idle periods the pump circulates unloaded through the switched relief path, which saves drive power and limits oil heating. The pressure setting is reached through an internal hexagon and secured against adjustment by a protective cap.
