Pressure Relief Valve DBW30BG2N5X/100YUS6EG24N9K4R12 - Bosch Rexroth R901383252

The DBW30BG2N5X/100YUS6EG24N9K4R12 limits system pressure to the set value and unloads the circuit on command through a built-on directional spool valve running at 24 VDC. In size 32 it passes up to 650 l/min at a maximum operating pressure of 350 bar.

Benefits

• Pressure adjustment range 2 ... 100 bar via an internal hexagon with a protective cap, giving a repeatable setting at the power unit.
• Solenoid unloading through the built-on directional spool valve with 2 switching positions at 24 VDC, so the pump can start against no pressure.
• Pilot operated design with a poppet seat pilot stage rated for a maximum flow of 650 l/min.
• Maximum operating pressure of 350 bar at a weight of 7 kg in size 32.
• Threaded connection to ISO 6264-10-17 with 3 ports, matching standard manifold blocks.
• Connector, 3-pole (2 + PE) to EN 175301-803 for quick solenoid coil replacement.

Application

The valve protects pump circuits and consumer branches in presses, injection moulding machines and stationary power units against overpressure. The 2 ... 100 bar range fits low pressure stages and prefill circuits, while the flow capacity of 650 l/min also accepts large pump deliveries. Solenoid unloading lets the pump idle without pressure, which cuts drive power and oil heating.
