A pump delivering against the relief valve turns drive power into heat. The DBW30B2-5X/315S6EG24N9K4R12V switches the circuit to unloaded circulation through its solenoid and limits between 4 and 315 bar in service.

The second switching state of this series is the real gain in continuous duty. The DBW30B2-5X/315S6EG24N9K4R12V takes pressure fully off through solenoid unloading and limits working pressure to a value between 4 and 315 bar.

Benefits

  • Solenoid unloading in two switching positions, unloaded circulation while the plant is idle.
  • Adjustment range 4 to 315 bar at 350 bar maximum operating pressure.
  • 650 l/min in size 32, interface ISO 6264-10-17.
  • FKM seals for HL hydraulic fluid.
  • 7 kg, 3-pole connector (2 + PE) to EN 175301-803.

Application

The valve suits power units with long pauses between working cycles. In the unloaded state the drive motor draws markedly less power and the oil heats up less. Switching between both states runs on 24 V DC from the machine control.
