Pumpensicherheitsblock DBAWR40BH2N1X/315YUS6EG24N9K4R12 - Bosch Rexroth R901100423

The pump safety block DBAWR40BH2N1X/315YUS6EG24N9K4R12 limits pressure at the pump outlet and unloads the circuit through a built-on directional valve. In size 40 it discharges up to 450 l/min, with a setting range from 0.8 to 315 bar.

Advantages

• Pressure relief and electrical unloading combined in one block
• Setting range 0.8 to 315 bar through an internal hexagon with protective cap
• Flow up to 450 l/min, operating pressure up to a maximum of 350 bar
• Pilot-operated pressure valve in poppet seat design, high-pressure flange connection
• Three ports, unloading through a built-on directional spool valve at 24 V DC
• NBR seals, size 40, weight 14.64 kg

Application

The block sits directly at the outlet of large pumps and performs two jobs at once: it limits system pressure and switches the pump to circulation during idle phases. A separate assembly of relief valve and unloading valve therefore becomes unnecessary. The high-pressure flange absorbs the forces of large line cross sections.
