Pressure Relief Valve DBW20BG2-5X/100-6EG24N9K4E - Bosch Rexroth R901013449

The pilot-operated DBW20BG2-5X/100-6EG24N9K4E limits system pressure across a 3.8 to 100 bar setting range and switches the pump to unloaded circulation through a mounted directional spool valve. Flow reaches 400 l/min at a maximum operating pressure of 350 bar. Setting is made through an internal hexagon under a protective cap.

Benefits

• Setting range 3.8 to 100 bar, adjusted by internal hexagon and covered by a protective cap
• Solenoid unloading through a mounted directional spool valve, switched on 24 VDC
• Up to 400 l/min in size 25 at a maximum operating pressure of 350 bar
• Threaded connection to ISO 6264-08-13, so no separate subplate is needed
• Poppet seat design, NBR seals matched to HL hydraulic fluid, 6.85 kg

Application

It serves as pump protection on power units whose working pressure stays below 100 bar, for example on clamping rigs and conveying equipment. Unloaded circulation saves drive power during idle periods and keeps oil temperature down. The threaded ports allow installation without a dedicated subplate.
