Pressure Relief Valve DBW30B1N5X/200-6EG24N9K4E - Bosch Rexroth R901172388

Cylinder circuits working around 200 bar benefit from a scale that ends right there, because the cut-off point can be hit more precisely. This pilot-operated pressure relief valve covers 4 to 200 bar and discharges up to 580 l/min through its subplate connection.

Benefits

• Setting range of 4 to 200 bar at the rotary knob, adjustable at the power unit without tools.
• Pilot-operated design keeps pressure stable across the flow range up to 580 l/min.
• Seat valve that closes tightly at rest and limits leakage.
• Maximum operating pressure of 350 bar as the body limit above the scale.
• Two switching positions with electrical unloading at 24 VDC.
• 6.59 kg weight, connection diagram ISO 6264-10-17.

Application

Intended for feed and clamping cylinders, hydraulic power units and test benches working around 200 bar. The rotary knob adapts the value when the product changes. During pauses the solenoid drops the circuit to zero pressure, which limits heating of the HL hydraulic fluid.
