Running a large axis under closed loop control calls for flow and resolution at once. In size 27 the 4WRLE27V1 passes up to 1850 l/min, at a nominal flow of 600 l/min and 270 bar. Main spool position control runs inside the on-board electronics.

Large press and test axes need flow without losing positioning accuracy. The 4WRLE27V1-600L-4X/VPT/24F1 works with internal spool position feedback and supplies 600 l/min nominal flow at 270 bar operating pressure.
Benefits
- 1850 l/min maximum flow in size 27, ISO 4401-08-07-0-05 interface for subplate mounting.
- 600 l/min nominal flow at 270 bar, pilot-operated spool design with three switching positions and four ports.
- Command value 4 to 20 mA at the on-board electronics, supplied with 24 VDC through a 7-pole connector (6 + PE) to EN 175201-804.
- Symbol V1 with internal pilot oil supply and internal pilot oil return, so no separate X and Y lines are needed at the subplate.
- FKM seals for HL hydraulic fluid at 20.72 kg valve weight, CE conformity.

Application
The valve controls speed and position of large cylinders in presses, rolling mills and test rigs. Internal spool position feedback keeps the deviation from the command value small even when the load jumps inside a cycle. Peak flow of 1850 l/min covers rapid traverse stages that are then trimmed precisely.
Manufacturer
