Pressure Relief Valve DBW30B1N5X/315-6EG24N9K4E - Bosch Rexroth R901307713

Machines that draw their force from high pressure need a relief stage whose scale reaches close to the body limit. This pilot-operated pressure relief valve covers 4 to 315 bar and discharges up to 580 l/min through the size 32 subplate connection.

Benefits

• Setting range of 4 to 315 bar at the rotary knob, so the upper working band is reached without changing the valve.
• Maximum operating pressure of 350 bar, leaving a margin between the top setting and the body limit.
• Pilot-operated seat valve design closes tightly even at high held pressure.
• 580 l/min maximum flow at 6.64 kg weight.
• Electrical unloading at 24 VDC across two switching positions.
• Connection diagram ISO 6264-10-17 for mounting on standard subplates.

Application

Typical for presses, punching machines and clamping systems working in the upper pressure band. The rotary knob allows fine trimming of the cut-off pressure when a new batch is run in. During pauses the solenoid drops the circuit to zero pressure and relieves the pump and the HL hydraulic fluid.
