Pumpensicherheitsblock DBAWR30BH2-1X/315S6EG24N9DK25LR12 - Bosch Rexroth R900905989

When a hydraulic power unit starts up, the pump should first deliver against low resistance, yet be reliably protected in operation. The pilot-operated pump safety block DBAWR30BH2-1X/315S6EG24N9DK25LR12 in size 32 combines both tasks and works up to 350 l/min at a maximum of 350 bar.

Advantages

• Pressure limitation in poppet seat design with a setting range of 3.7 to 315 bar, internal hexagon with protective cap.
• Electrical unloading through a built-on directional spool valve with two switching positions and solenoid actuation at 24 VDC.
• Flow of up to 350 l/min at a maximum of 350 bar operating pressure.
• High-pressure flange as the type of connection in size 32 with two ports.
• Connector, 5-pole according to ANSI/B93.55M-1981 for the electrical control signal.
• Weight of 10.84 kg, laid out for HL hydraulic fluid with NBR seals.

Technical data

Application

The block sits directly on the pressure port of the pump and handles protection and unloading there, for example on power units of presses, test rigs and machine tools. Through the built-on directional valve the control system can unload the pump at start-up and during idle periods without switching the drive motor. The size 32 high-pressure flange takes flows of up to 350 l/min. Pressure is set through the internal hexagon, and the protective cap keeps the setting from being changed unintentionally.

Manufacturer

Bosch Rexroth, material number R900905989, product family DBA(W). According to the type code the pressure setting range runs from 3.7 to 315 bar, and the connection is made through the size 32 high-pressure flange.
