Pressure Relief Valve DBW20B2-5X/50-6EG24N9K4/12=CSA - Bosch Rexroth R901085783

Charge and flushing pressures sit far below the working pressure of a plant and must stay constant all the same. The pilot-operated DBW20B2-5X/50-6EG24N9K4/12=CSA covers 4 to 50 bar with its spring and still discharges up to 500 l/min.

Benefits

• Adjustment range 4 to 50 bar for charge, flushing and back pressure circuits.
• 500 l/min in size 25, the circuit is not dammed up even at high throughput.
• Pilot-operated seat valve, symbol B, two ports and two switching positions.
• Subplate mounting to ISO 6264-08-13, solenoid actuation on 24 VDC.
• 5.24 kg, internal hexagon with protective cap, NBR seals for HL hydraulic fluid.

Applications

The valve limits charge circuits of closed loops as well as flushing and cooling oil circuits. Because the permitted operating pressure is 350 bar, the body also withstands spikes from the adjoining high pressure section. The setting is fixed at commissioning and secured with the protective cap.
