Pressure Reducing Valve DRE20-6X/315YG24K4M - Bosch Rexroth R901483398

When the pressure of a branch has to be changed from the control system, this size 25 version does the job. It regulates steplessly to the command value, works up to a maximum operating pressure of 315 bar and passes a flow of up to 300 l/min.

Benefits

• Size 25 - the subplate mounting to ISO 5781 carries 3 ports and stays compatible with the standard pattern.
• 315 bar maximum operating pressure - the command value range extends into the upper pressure range of the power unit.
• 300 l/min maximum flow - enough throughput for larger cylinders on a single branch.
• NBR seals - matched to HL hydraulic fluid in the usual temperature range.
• 24 VDC, 2 switching positions - driven by external electronics through a 3-pole connector to EN 175301-803.
• 5.8 kg weight - one person can change the valve on the plate.

Applications

In presses, clamping fixtures and power units built around a size 25 subplate, the valve keeps one branch at the set pressure while the main circuit stays higher. At 300 l/min there is still headroom when several actuators share that branch. The NBR seals are matched to HL hydraulic fluid.
