Pressure Relief Valve DBW20BG2-5X/315-6EG24N9K4/12=CSA - Bosch Rexroth R900727697

At 315 bar system pressure every pause in which the pump delivers against the relief valve tells on the energy bill. The DBW20BG2-5X/315-6EG24N9K4/12=CSA takes that pressure away through a built-on directional spool valve and limits operation to 3.8 to 315 bar.

Benefits

• Solenoid unloading through a built-on directional spool valve, the pump circulates without pressure during the pause.
• Adjustment range 3.8 to 315 bar at a permitted operating pressure of 350 bar.
