Pressure Relief Valve DBW30A1N5X/210-6EG24N9K4E - Bosch Rexroth R901362258

When the cut-off pressure of a system has to be readjusted during operation, a valve with a directly accessible rotary knob saves time. This pilot-operated pressure relief valve covers 4 to 210 bar, uses size 32 subplate mounting and passes up to 580 l/min.

Benefits

• Rotary knob for pressure adjustment from 4 to 210 bar, readjustment at the machine without tools.
• Maximum operating pressure of 350 bar, so the full setting range stays below the component limit.
• Seat valve design that closes tightly at rest and keeps leakage low.
• Solenoid actuation at 24 VDC through a connector, 3-pole (2 + PE) according to EN 175301-803 for electrical unloading.
• Subplate mounting to connection diagram ISO 6264-10-17 for assembly on standard plates.
• 6.6 kg weight at 580 l/min maximum flow.

Application

Typical places are hydraulic power units where system pressure is matched to the tool or the batch. The rotary knob allows trimming while the process runs, and electrical unloading lowers circulating pressure during waiting times. Approved for HL fluid with NBR seals.
