Pumpensicherheitsblock DBAW40BH2N1X/70S6EG24N9K4R12E - Bosch Rexroth R901368128

The spring of this pressure valve is rated for a limiting pressure between 3.7 and 70 bar. That makes the target value easy to hit in the low band without fitting a valve for the full pressure range. The built-on directional spool valve additionally unloads the pump at 24 VDC.

Benefits

• Adjustment range of 3.7 to 70 bar for circuits with a low working pressure
• Flow of up to 500 l/min in size 40 at a maximum operating pressure of 350 bar
• Electrical unloading through the built-on directional spool valve at 24 VDC
• Pressure valve in poppet seat design, keeping leakage low while closed
• Internal hexagon with a protective cap secures the set value
• High-pressure flange, NBR seals for HL hydraulic fluid, CE conformity, weight of 13.88 kg

Applications

The block protects feed, clamping and circulation circuits whose consumers can take only limited load. Despite the low limiting pressure, the housing stays rated for 350 bar operating pressure. Electrical unloading leaves the circuit without pressure during pauses.
