Pressure Reducing Valve DRE20-6X/100YMG24-8K4M - Bosch Rexroth R901350327

A fixed pressure reducing valve has to be readjusted by hand whenever the process changes. The DRE20-6X/100YMG24-8K4M instead reduces pressure steplessly to the electrical command value and handles up to 300 l/min in size 25.

Benefits

• Stepless pressure reduction to the command value, driven electrically with external electronics
• 300 l/min flow at a maximum operating pressure of 315 bar
• Subplate mounting to ISO 5781 with 3 ports and 2 switching positions
• Flow direction B to A as stated in the manufacturer symbol
• 5.96 kg weight, 24 VDC supply through a 3-pole (2 + PE) connector to EN 175301-803
• NBR seals for HL hydraulic fluid

Application

The valve belongs wherever a single consumer runs at a lower pressure than the rest of the circuit, for example a clamping fixture on a press or a feed drive. The electrical command value lets the reduced pressure be changed during the running cycle without opening up the system. Controller design and output stage sit in the external electronics, so the valve itself stays a purely hydraulic bolt-on part.

Manufacturer

Bosch Rexroth lists the valve under material number R901350327. Characteristic curves, command value range and mounting dimensions are given in datasheet RE 29276, with RE 07600-B as further reading.
