Pressure Relief Valve DBW30B3-5X/315YS6EG24N9K4R12 - Bosch Rexroth R901303060

Protecting a large pump means the relief valve has to carry the full delivery flow. This pilot-operated seat valve in size 32 passes up to 650 l/min, covers an adjustment range of 4 to 315 bar and is set repeatably on a lockable rotary knob with a scale.

Benefits

• 650 l/min relief capacity through the ISO 6264-10-17 interface
• Adjustment range of 4 to 315 bar at a maximum operating pressure of 350 bar
• Lockable rotary knob with a scale, so the setting stays secured after commissioning
• Seat valve design in the pilot stage, which keeps leakage low in the closed state
• Electrical unloading through the mounted solenoid at 24 VDC
• Subplate mounting and a weight of 7.08 kg, so a swap leaves the piping untouched

Applications

It protects pump circuits in presses, hydraulic power units and test rigs whose delivery flow approaches 650 l/min. The solenoid lets the circuit run pressureless during breaks without stopping the pump. The lockable knob prevents an unintended change of setting during operation.
