Pressure Relief Valve DBW30B1-5X/350S6EG24N9DLR12 - Bosch Rexroth R900755861

A setting range of 4 to 350 bar takes the DBW30B1-5X/350S6EG24N9DLR12 right up to its 350 bar maximum operating pressure, dialled in at the rotary knob without tools. The pilot-operated seat valve is a size 32 unit for subplate mounting to ISO 6264-10-17 carrying up to 650 l/min. Spool symbol B covers two switching positions across two ports at a weight of 6.4 kg.

Benefits

• Pressure setting from 4 to 350 bar at the rotary knob, maximum operating pressure 350 bar
• 650 l/min flow in size 32
• Subplate mounting to pattern ISO 6264-10-17 with 2 ports
• Spool symbol B, 2 switching positions, pilot-operated seat design
• Electrical unloading at 24 VDC through a 3-pole connector (2 + PE) to EN 175301-803
• NBR seals rated to HL hydraulic fluid, weight 6.4 kg

Applications

On a power unit the valve sits on its subplate, limiting pump pressure to the value dialled in at the knob. Because unloading runs electrically, the controller can drop the system to zero pressure while the drive keeps running. Rate subplate plus fittings to 350 bar at 650 l/min.
