Pumpensicherheitsblock DBAWR40BH2N1X/240-6EG24N9K4E - Bosch Rexroth R901464106

On a power unit rated 600 l/min the return path decides how much the oil heats up. This pilot-operated safety block in size 40 takes the full flow, limits system pressure to a value set between 3.7 and 240 bar and switches the pump to pressureless circulation by solenoid.

Benefits

• Flow of up to 600 l/min through the high-pressure flange, the port is rated for an operating pressure of 350 bar maximum
• Setting range of 3.7 to 240 bar, which allows a fine preselection in the lower pressure band as well
• Solenoid unloading on 24 VDC with two switching positions through a built-on directional spool valve
• Pilot-operated pressure stage in poppet seat design with internal hexagon and protective cap
• CE conformity, NBR seals, 3-pole connector to EN 175301-803 and a mass of 14.13 kg

Applications

The usual place is the power unit of large presses, forging lines and hydraulic stations in steel construction. There the block is flanged straight onto the pump outlet and covers protection and unloading. Lifting gear is sensible for installation and transport because of the mass.

Manufacturer

The block belongs to the Rexroth DBA(W) range. The Bosch Rexroth material number is R901464106.
