Pressure Relief Valve DBW30B2-5X/315YUS6EG24N9K4R12 - Bosch Rexroth R900929633

Accumulators store energy for hours, so the response accuracy of the relief valve decides how safe the circuit is. The pilot-operated DBW30B2-5X/315YUS6EG24N9K4R12 in size 32 limits to a setting of 2 to 315 bar and discharges up to 650 l/min.

Benefits

• Adjustment range 2 to 315 bar at a permitted operating pressure of 350 bar.
• 650 l/min flow through two ports in size 32.
• Pilot-operated seat valve, symbol B, two switching positions, solenoid actuation on 24 VDC.
• Internal hexagon with protective cap so the setting does not shift in service.
• 6.9 kg, subplate mounting ISO 6264-10-17, connector 3-pole (2 + PE) to EN 175301-803.

Applications

It is installed in the pump or accumulator branch of power units for presses, test rigs and forming equipment. An adjustment range up to 315 bar keeps a margin to the permitted maximum of 350 bar. The solenoid selects the second switching position, for instance when the plant is shut down.
