Pumpensicherheitsblock DBAW40BH2N1X/100-6EG24N9K4 - Bosch Rexroth R900972544

A pump safety block combines pressure limitation and electrical unloading in one body, saving pipework at the power unit. This version of the DBAW40BH2N1X works across a setting range of 3.7 to 100 bar at 650 l/min.

Benefits

• Setting range 3.7 to 100 bar for circuits in the lower pressure band.
• High-pressure flange SAE 1 1/2 to ISO 6162-2, bolted straight onto the pump.
• Unloading by a built-on directional spool valve, 24 VDC solenoid.
• 650 l/min rated flow in size 40, operating pressure up to 350 bar.
• 13.5 kg, pressure valve in poppet seat design, NBR seals for HL fluid.

Application

The block sits right at the pressure port of the pump and handles protection plus start-up unloading in a single housing. A ceiling of 100 bar points at circuits with large actuator areas or at preload duties. A flange joint transmits considerable force and needs a load-bearing mount.
