Pumpensicherheitsblock DBAW40BH2N1X/160S6EG24N9K4R12E - Bosch Rexroth R901545739

During start-up and idle periods the built-on directional spool valve routes the pump flow to tank without pressure. In working duty the pilot-operated seat valve limits the pressure to the set value, and up to 500 l/min can drain in the process.

Benefits

• Electrical unloading through the built-on directional spool valve, so the motor starts against no back pressure
• Less heat input during idle periods, because the flow goes to tank without pressure
• Adjustment range of 3.7 to 160 bar at a maximum operating pressure of 350 bar
• Flow of up to 500 l/min in size 40
• Internal hexagon with a protective cap, high-pressure flange connection
• Solenoid actuation at 24 VDC through a 3-pole connector (2 + PE) according to EN 175301-803, weight of 13.34 kg

Applications

Blocks of this kind belong on power units that start often or hold pressure for long spells. They protect the circuit against excess pressure and keep the oil temperature down during pauses. The high-pressure flange connection carries the forces of size 40.
