Pumpensicherheitsblock DBAWR40BF1N1X/200S6EG24N9K4R12 - Bosch Rexroth R900756487

The key BF1 marks the rotary knob on the adjustment spindle, the figure 200 the pressure rating. The block limits pump pressure in a pilot-operated poppet seat and takes the system off load through a built-on directional spool valve at 24 VDC.

Benefits

• Rotary knob instead of an internal hexagon, readjustment without a tool while running
• Adjustment range 3.7 to 200 bar at a maximum operating pressure of 350 bar
• Flow up to 450 l/min through the size 40 flange connection
• Mass 14.6 kg with 2 ports and NBR seals
• Solenoid unloading, 2 switching positions at 24 VDC, connector 3-pole (2 + PE) according to EN 175301-803

Application

The block belongs on power units of test benches and setup stations where holding pressure changes with the workpiece. The rotary knob allows adjustment in a running circuit and the range up to 200 bar covers common clamping duties. During waiting periods the solenoid takes pressure off the pump.
