Pressure Relief Valve DBW52AF2-3X/315YU6EG24NK4 - Bosch Rexroth R901192750

A power unit with a large pump flow needs pressure relief that can pass the full flow and be unloaded for start-up. The size 52 DBW52AF2-3X/315YU6EG24NK4 handles up to 2000 l/min maximum flow and limits pressure across a range of 3.9 to 315 bar.

Benefits

• Size 52 with flange connection and 3 ports, maximum flow 2000 l/min.
• Pressure adjustment range 3.9 to 315 bar through an internal hexagon with a protective cap.
• A built-on directional valve unloads the circuit by solenoid, with 2 switching positions and solenoid actuation at 24 VDC.
• Pilot-operated pressure valve in poppet seat design with spool symbol A.
• Electrical connection through a 3-pole connector (2 + PE) to EN 175301-803.
• NBR seals for HL fluid, maximum operating pressure 315 bar, weight 28.68 kg.

Applications

Valves like this serve as system pressure relief in large power units for presses, rolling mills and test fields. Solenoid unloading lets the pump start against no pressure and lets the circuit be relieved during pauses without switching the pump off. The flange connection takes the full flow without throttling the line.
