Pressure Relief Valve DBW30B2-5X/315US6EG24N9K4R12 - Bosch Rexroth R901066220

A size 32 power unit has to hold its system pressure even when the actuator closes abruptly. The pilot-operated DBW30B2-5X/315US6EG24N9K4R12 pressure relief valve limits to a setting between 2 and 315 bar and returns up to 650 l/min to tank.

Benefits

• Pressure adjustment range 2 to 315 bar, set through the internal hexagon and then secured by the protective cap.
• 650 l/min flow at a maximum operating pressure of 350 bar.
• Pilot-operated seat valve with two switching positions and solenoid actuation on 24 VDC.
• Subplate mounting to ISO 6264-10-17, two ports, matched to size 32.
• 7.02 kg, NBR seals, released for HL hydraulic fluid.

Applications

The valve sits in the pressure line of power units feeding presses, clamping fixtures or test rigs. A setting range up to 315 bar covers the usual working pressure of such plants, and 650 l/min allows several actuators to run in parallel. The 24 VDC solenoid selects the second switching position without any change to the circuit.
