Total price
Serving three switching positions in size 16 while keeping the pilot stage clear of the working circuit is what this version is for. The 4WEH 16 U7X/6EG24N9K4/B10 carries up to 300 l/min and is shifted through a fully external pilot oil circuit.
Benefits
- Symbol U spool diagram with three positions across four ports.
- Pilot oil fed and returned externally, so switching behaviour does not follow the working pressure.
- 300 l/min rated flow at a maximum operating pressure of 280 bar.
- Subplate mounting to ISO 4401-07-07-0-05, the valve sits on the subplate without an adapter.
- Solenoid for 24 VDC with a 3-pole connector (2 + PE) to EN 175301-803, NBR seals for HL hydraulic fluid, 8.9 kg in weight.

Applications
Size 16 works on cylinders that swallow large oil volumes in rapid traverse, for example on presses and lift tables. A fully external pilot circuit makes sense where the working pressure drops sharply within the cycle and the pilot stage still has to shift. At 8.9 kg the valve sits on a subplate to ISO 4401-07-07-0-05.
