Pumpensicherheitsblock DBAWR40BH3N1X/200-6EG24N9K4 - Bosch Rexroth R901478614

A power unit has to limit its pressure reliably and still start up unloaded. The pump safety block DBAWR40BH3N1X/200-6EG24N9K4 combines both functions in one component and handles flows up to 450 l/min.

Benefits

• Pressure adjustment range 3.7 to 200 bar via a lockable rotary knob with scale.
• 450 l/min flow in size 40 through a high-pressure flange.
• Electrical unloading at 24 VDC via a built-on directional spool valve, two switching positions.
• Pilot-operated pressure valve in poppet seat design, spool symbol B.
• 350 bar maximum operating pressure, NBR seals for HL fluid.
• 13.7 kg, connector 3-pole (2 + PE) according to EN 175301-803.

Application

Large power units running around 450 l/min need pressure limitation right at the pump outlet. This block handles limitation and unloading together, so the drive can run up without back pressure. The lockable rotary knob with scale holds the chosen setting anywhere between 3.7 and 200 bar. The size 40 high-pressure flange connects the block straight to the pipework.
