The DBW20BG1-5X/315-6EG24N9K4E is the rotary knob version and covers a setting range of 3.8 to 315 bar. It is pilot-operated, passes up to 400 l/min and holds a maximum operating pressure of 350 bar. The mounted directional spool valve switches the pump electrically to unloaded circulation.

Benefits

• Setting range 3.8 to 315 bar, reset by rotary knob without tools
• 400 l/min flow at 350 bar maximum operating pressure, size 25
• Solenoid unloading on 24 VDC through the mounted directional spool valve
• Threaded connection to ISO 6264-08-13, poppet seat design, 2 ports
• NBR seals matched to HL hydraulic fluid, 6.5 kg

Application

The valve protects power units running at changing working pressures, for example on test benches and development rigs. A setting range reaching 315 bar also covers circuits with high clamping or pressing forces. Threaded ports are an advantage when retrofitting existing plant.
