Pumpensicherheitsblock DBAWR40BH2N1X/315-6EG24N9K4VE - Bosch Rexroth R901384667

Electrical unloading is the reason a safety block is chosen over a plain pressure relief valve. The DBAWR40 switches a built-on directional spool valve at 24 VDC for it and limits pressure between 3.7 and 315 bar at 600 l/min.

Benefits

• Solenoid pump unloading through a built-on directional spool valve, 24 VDC
• Pressure limitation from 3.7 to 315 bar, set through an internal hexagon with protective cap
• 600 l/min flow, maximum operating pressure 350 bar
• FKM seals for HL hydraulic fluid
• Size 40 high-pressure flange, two ports, symbol B
• CE conformity, 3-pole connector (2 + PE) according to EN 175301-803, 13.86 kg

Applications

The block is placed directly at the pump outlet and covers pressure limitation and circulation switching there. During breaks the pump circulates without pressure, which cuts heat input and current draw. Flow of 600 l/min is the figure that counts for sizing.
