For a press cylinder that has to hold its speed under changing load, this pilot-operated proportional directional valve in size 35 meters up to 1000 l/min with closed-loop spool position control. Operating pressure reaches 350 bar and the command value is analog at ±10 V, with external pilot oil supply and return.

A press cylinder must keep a clean velocity profile over the full stroke even when the load changes abruptly. The 4WRKE35W6-1000L-3X/6EG24K31/A1D3M delivers 1000 l/min nominal flow at 350 bar operating pressure, and the on-board electronics keep the spool on the command value through internal position feedback.
Benefits
- 1000 l/min nominal flow in size 35, with a peak capability of 3000 l/min.
- 350 bar operating pressure in the main circuit, connection diagram ISO 4401-10-09-0-05 for subplate mounting.
- Spool symbol W6 with a linear characteristic curve, three switching positions across four ports.
- External pilot oil supply and external pilot oil return keep the pilot stage independent of main circuit pressure.
- Command value ±10 V at 24 VDC through a 7-pole connector (6 + PE) to EN 175201-804.
