Pressure Relief Valve DBW30B2N5X/230Y6EG24N9K4E - Bosch Rexroth R901032421

High delivery and a working pressure above the 210 bar stage meet in many forming lines. This pilot-operated pressure relief valve discharges up to 700 l/min and caps pressure from 4 to 230 bar.

Benefits

• 700 l/min permitted flow with a setting range reaching 230 bar.
• Internal hexagon under a protective cap, so the cut-off stays unchanged in operation.
• Pilot-operated seat valve holds pressure across the entire flow range.
• Maximum operating pressure of 350 bar above the setting range.
• Electrical unloading at 24 VDC across two switching positions.
• 6.45 kg weight in size 32.

Technical data

Application

Suited to presses, bending machines and central power units feeding several consumers in parallel. The high permitted flow also covers brief load peaks. The solenoid switches the circuit to zero pressure during setup, and the NBR seals match HL hydraulic fluid.
