Pressure Relief Valve DBW30B2-5X/315XYU6EG24N9K4V/12 - Bosch Rexroth R901375745

The key XY marks the separated supply and drain of pilot oil. Pressure is limited in a pilot-operated seat to a value between 2 and 315 bar, set through an internal hexagon under a protective cap. The valve sits on a port pattern to ISO 6264-10-17.

Benefits

• Separate pilot paths X and Y, independent of back pressure in the return line
• Adjustment range 2 to 315 bar at an operating pressure of 350 bar maximum
• Flow up to 650 l/min, subplate mounting to ISO 6264-10-17
• Spool symbol B, solenoid stage at 24 VDC
• Mass 5.6 kg, FKM seals for HL hydraulic fluid

Application

The valve limits pressure in circuits whose return runs through a cooler or filter and therefore builds back pressure. Separate pilot paths keep the setting untouched by that. Flow up to 650 l/min matches power units with large pumps.
