Pumpensicherheitsblock DBAW25BH2-2X/230ZZ6EG24N9K4A00E - Bosch Rexroth R901577653

A safety block at the pump outlet has to take the full flow without letting pressure climb above the set value. The DBAW25BH2-2X/230ZZ6EG24N9K4A00E in size 25 holds 6 to 230 bar at flows up to 300 l/min.

Benefits

• Pressure adjustment range 6 to 230 bar, maximum operating pressure 350 bar.
• Up to 300 l/min across two ports on the size 25 high-pressure flange.
• Built-on directional spool valve for solenoid unloading at 24 VDC with symbol B.
• Poppet seat design of the pressure valve for low leakage in the closed state.
• NBR seals, HL hydraulic fluid, connector 3-pole (2 + PE) according to EN 175301-803.
• 7.9 kg mass, CE conformity.

Applications

The block goes on power units feeding presses or clamping cylinders at 230 bar. With the cylinder against its end stop, the pressure valve carries the surplus flow off to tank. For setup and maintenance work, solenoid unloading takes the circuit pressureless.
