Pumpensicherheitsblock DBAW40BH2N1X/315S6EG24N9K4R12E - Bosch Rexroth R901085409

The pilot-operated seat valve limits the system to the value set once, up to 315 bar. The protective cap over the internal hexagon holds that setting, while the built-on directional spool valve unloads the pump at 24 VDC.

Benefits

• Adjustment range of 3.7 to 315 bar, secured by the internal hexagon with a protective cap
• Flow of up to 500 l/min in size 40 at a maximum operating pressure of 350 bar
• Electrical unloading through the built-on directional spool valve at 24 VDC
• Pressure valve in poppet seat design, closing tightly below the limiting pressure
• Two ports through a high-pressure flange
• NBR seals for HL hydraulic fluid, CE conformity, weight of 13.82 kg

Technical data
