Pumpensicherheitsblock DBAWR30BH2N1X/210S6EG24N9K4R12E - Bosch Rexroth R901144096

The pump has to be protected and started without pressure, and two separate valves should not be needed for it. The DBAWR30BH2N1X safety block does both and covers 3.7 to 210 bar.

Benefits

• Solenoid unloading through a built-on directional spool valve, switched electrically on 24 V DC.
• Adjustment range of 3.7 to 210 bar at a maximum operating pressure of 350 bar.
• 520 l/min of flow in size 32.
• High-pressure flange for direct assembly onto the pump port.
• Internal hexagon with protective cap, pressure valve in poppet seat design, spool symbol B.
• 10.9 kg, NBR seals, 3-pole connector (2 + PE) to EN 175301-803.

Applications

The block sits directly on the pump outlet and handles pressure limitation and unloading there. During start-up the unit can run up without pressure, which spares the drive. A range up to 210 bar suits power units in the medium pressure band.

Manufacturer

Bosch Rexroth lists the block under material number R901144096, product family DBA(W). Connection dimensions follow the size 32 high-pressure flange.
