Large cylinders need flow and still a settled end position. This pilot-operated proportional directional valve in size 25 carries 400 l/min nominal flow at 350 bar and closes the position loop with an integrated digital axis controller. Pilot oil is supplied and returned externally.

Total price
The MXY version is meant for axes whose pilot circuit runs off a separate control pressure line: both pilot oil supply and pilot oil return are external. In the main circuit the valve handles 400 l/min nominal flow at 350 bar operating pressure, controlled through spool symbol V.
Key benefits
- 400 l/min nominal flow in size 25, up to 1250 l/min maximum flow for fast strokes on large cylinders.
- 350 bar operating pressure covers press and forming circuits at the upper end of the range.
- Spool symbol V with 3 switching positions and 4 ports for the classic four-way function.
- Integrated digital axis controller with a ±10 V command value, no separate amplifier needed in the cabinet.
- External pilot oil supply and external pilot oil return keep the control circuit independent of main line pressure.
- 18.9 kg installed weight, subplate mounting to ISO 4401-08-08-0-05, 12-pole connector (11 + PE) to EN 175201-804.

Applications
Size 25 is used on presses, forging lines and large injection moulding machines that move several hundred litres per stroke. External pilot supply makes sense where the main circuit sees strongly varying pressure and the pilot stage should be fed at a steady level. The NBR seals match HL hydraulic fluid.
