Pressure Reducing Valve DRE10-6X/315YG24-8K4V - Bosch Rexroth R901346991

A downstream actuator often needs less pressure than the pump delivers. This proportional pressure reducing valve of size 10 lowers the pressure steplessly to the electrical command value and holds it up to a maximum operating pressure of 315 bar at a flow of up to 300 l/min.

Benefits

• 315 bar maximum operating pressure - the reduced pressure stays adjustable even in circuits with high pump pressure.
• 300 l/min maximum flow - headroom for actuators fed from a size 10 subplate.
• 24 VDC with external electronics - the command value comes from the machine amplifier, no electronics sit inside the valve.
• FKM seals - matched to HL hydraulic fluid under raised thermal load.
• Subplate mounting to ISO 5781 - standardised pattern with 3 ports, so a swap needs no rework of the plate.
• 4.7 kg weight - manageable during installation and replacement on a built-in power unit.

Applications

The valve is used in clamping and pressing circuits where the force is set through the reduced pressure. Test benches also rely on the stepless command value because a sequence can then run without manual adjustment. A subplate to ISO 5781 and an amplifier that supplies the command value signal are required.
