Proportional Directional Valve 4WRTE25V1-220L-4X/6EG24EK31/A1M - Bosch Rexroth R900962046

When an open-loop valve is replaced by a closed-loop one the wiring stays the same and the accuracy changes. Internal position feedback corrects every deviation in spool travel here, at 220 l/min nominal flow and 350 bar.

Benefits

• Internal position feedback replaces the fixed characteristic of an open-loop valve
• Command value ±10 V, already available in most existing control systems
• Nominal flow 220 l/min, up to 870 l/min through the valve at 350 bar
• Internal pilot oil supply with external return, V1 spool
• Port pattern ISO 4401-08-08-0-05, so it fits existing size 25 subplates
• Weight 17.98 kg, 24 VDC supply

Application

The variant is fitted when modernising test rigs, presses and forming machines whose positioning accuracy no longer suffices. The port pattern is unchanged, so the existing subplate can stay. Operation is on HL hydraulic fluid with NBR seals.
