Proportional Directional Valve 4WRLE25E400LJ-4X/VPY/24A1 - Bosch Rexroth R901556062

If you need to hold the spool itself under closed-loop position control rather than merely move the axis, internal piston position feedback is what it takes. This size 25 valve brings it, converts 400 l/min nominal flow and allows up to 1250 l/min on the valve side.

Benefits

• Internal piston position feedback, giving high accuracy and low hysteresis of the spool position
• 400 l/min nominal flow against a valve maximum of 1250 l/min
• Internal pilot feed without a dedicated pilot pump, external return through Y
• Spool symbol E, three switching positions, operating pressure up to 350 bar
• ±10 V command value on the on-board electronics, mass 19.34 kg, CE conformity

Technical data

Application

This design is asked for in fast position and force control loops, for example on forming presses, forging manipulators and servo-hydraulic test cylinders. The external Y return keeps pilot control free of back pressure in the collecting return line. The ISO 4401-08-08-0-05 mounting pattern matches the usual size 25 standard.
