Pumpensicherheitsblock DBAW15BF2-2X/315-6EG24K4QM0G24A08 - Bosch Rexroth R901371804

Building pressure limitation and solenoid unloading separately means piping two valves and accepting extra leak points. The DBAW15BF2-2X/315-6EG24K4QM0G24A08 pump safety block unites the pilot-operated poppet seat pressure valve and the built-on directional spool valve in one flange-mounted assembly of size 16, adjustable from 6 to 315 bar.

Benefits

• Adjustment range 6 to 315 bar with internal hexagon and protective cap.
• Solenoid unloading through a built-on directional spool valve, switched at 24 VDC.
• 300 l/min relief flow at a maximum operating pressure of 350 bar.
• Poppet seat design for low-leakage sealing up to the cracking pressure.
• Flange connection to ISO 4401-03-02-0-05, weight 6.08 kg.

Application

The block sits directly at the pump outlet of presses and hydraulic power units whose circuit alternates between working stroke and circulation. The flange connection saves the intermediate piping between pressure valve and directional valve. NBR seals match hydraulic fluid HL across the usual temperature window.
