Pressure Relief Valve DBW30B2N5X/250-6EG24N9K4E - Bosch Rexroth R901019828

Systems at raised working pressure need a relief stage whose scale sits above the standard stage. This pilot-operated pressure relief valve covers 4 to 250 bar and discharges up to 580 l/min through its subplate connection.

Benefits

• Setting range of 4 to 250 bar against a maximum operating pressure of 350 bar.
• Internal hexagon under a protective cap keeps the value secure once set.
• Pilot-operated seat valve keeps pressure stable up to 580 l/min.
• Tight closing in the rest position with low leakage.
• Electrical unloading at 24 VDC across two switching positions.
• 6 kg weight with connection diagram ISO 6264-10-17.

Application

Intended for presses, clamping systems and test benches at raised working pressure. The concealed adjustment keeps the cut-off constant over the whole service life. The solenoid runs the circuit pressureless during pauses, and the NBR seals are rated for HL hydraulic fluid.
