Pressure Relief Valve DBW30B1N5X/120-6EG24N9K4E - Bosch Rexroth R901337112

Circuits that run permanently below 120 bar need a valve whose setting range sits exactly there. This pilot-operated pressure relief valve covers 4 to 120 bar, is adjusted with a rotary knob and discharges up to 580 l/min through the size 32 subplate connection.

Benefits

• Setting range of 4 to 120 bar, so the scale spreads across the pressure band actually used.
• Rotary knob adjustment for readjustment at the machine without tools.
• Maximum operating pressure of 350 bar, so the body is rated far above the setting range.
• Seat valve design that closes tightly in the rest position.
• Electrical unloading at 24 VDC across two switching positions.
• 6.49 kg weight at 580 l/min maximum flow.

Application

A fit for clamping and feed circuits, coolant systems and power units whose consumers work at low pressure. The rotary knob allows adaptation to changing workpieces. During waiting times the solenoid drops the circuit to zero pressure, and approval covers HL hydraulic fluid.
