Pressure Relief Valve DBW30B2-5X/200YUS6EG24N9K4R12 - Bosch Rexroth R900917594

When a plant works with two pressure stages, the lower stage needs its own limitation. The pilot-operated DBW30B2-5X/200YUS6EG24N9K4R12 takes on that job between 2 and 200 bar and still allows the full 650 l/min of size 32.

Benefits

• Adjustment range 2 to 200 bar for the lower step of a multi-stage circuit.
• 650 l/min through two ports, connection diagram ISO 6264-10-17.
• Two switching positions, symbol B, controlled by the solenoid on 24 VDC.
• Operating pressure permitted up to 350 bar, so the valve stays loadable during spikes in the branch.
• 7 kg, internal hexagon with protective cap, NBR seals.

Applications

The valve limits the low pressure stage in presses, clamping fixtures and power units with switchable pressure. Its second switching position is selected electrically, so pressure changeover happens from the control system. NBR seals are provided for mineral oil to HL.
