Pumpensicherheitsblock DBAWR40BF2N1X/200S6EG24N9K4R12 - Bosch Rexroth R900954049

The figure 200 in the type code fixes how far pressure can be set. The pilot stage works as a poppet seat and pilot oil returns internally, so 2 ports are enough. The solenoid at 24 VDC sends the pump into circulation.

Benefits

• Adjustment range 3.7 to 200 bar, fine enough to hold pressures below 10 bar
• Flow up to 450 l/min at an operating pressure of 350 bar maximum
• Poppet seat design gives a tight shut-off while pressure is held
• Flange connection in size 40, 2 ports, mass 14.72 kg
• Solenoid unloading across 2 switching positions at 24 VDC, HL hydraulic fluid

Application

Power units of presses, clamping systems and test rigs working up to 200 bar are the usual home for this block. The poppet seat keeps the setting stable through long holding periods. Between working strokes, circulation lowers the power the drive draws.
