Pumpensicherheitsblock DBAEE25BF2-2X/200G24K31A1A00 - Bosch Rexroth R901555337

The block sits between the pump and the machine and limits the pressure in the circuit. The setting arrives as an analogue signal of 0 to 10 V at the on-board electronics rather than through a manual spindle, so the controller can change pressure during operation. The DBAEE25BF2-2X/200 version is rated for 400 l/min at 350 bar.

Benefits

• 400 l/min flow at a maximum operating pressure of 350 bar in size 25.
• Analogue command value of 0 to 10 V, so pressure can be changed from the machine control.
• On-board electronics on 24 V DC, wired through a 7-pole connector (6 + PE) to EN 175201-804.
• Flange connection with two ports and two switching positions, weight 5.82 kg.

Application

The typical location is a power unit that runs several working pressures, for instance a press or a test rig with changing recipes. Instead of one valve per pressure level, the controller sets the value. The NBR seals match HL hydraulic fluid.

Manufacturer

The version comes from product family DBA.15,25,30. Bosch Rexroth lists the item under material number R901555337.
