Pressure Relief Valve DBW30BG2N5X/180-6EG24N9K4E - Bosch Rexroth R901350146

Once a cut-off pressure has been set, it should not drift in series production. This pilot-operated pressure relief valve is adjusted from 3.8 to 180 bar through an internal hexagon under a protective cap and passes up to 580 l/min through its threaded connection.

Benefits

• Setting range of 3.8 to 180 bar through an internal hexagon, with the protective cap holding the value in series duty.
• Solenoid unloading through a built-on directional spool valve at 24 VDC, two switching positions cover pressure and circulation.
• Poppet seat design closes tightly, which keeps leakage low while pressure is held.
• Maximum operating pressure of 350 bar, well above the top of the setting range.
• Threaded connection to connection diagram ISO 6264-10-17 for installation without a special plate.
• 6.5 kg weight at 580 l/min maximum flow.

Application

Intended for pump protection and pressure stages in power units, presses and machine tools running at a fixed process pressure. Electrical unloading drops the circuit to zero pressure during pauses and relieves the pump as well. Approval covers HL fluid, and the seals are NBR.
