Leaves the axis standing pressureless in mid position, because symbol W8 opens both cylinder ports to tank. This pilot operated proportional directional valve in size 16 runs 150 l/min of nominal flow up to 350 bar and carries FKM seals for higher oil temperatures.

Total price
Spool symbol W8 opens both cylinder ports to tank in mid position, leaving an axis standing without pressure. The 4WRDE16W8-150L delivers that behaviour with 150 l/min and FKM seals.
Benefits
- 150 l/min nominal flow covers continuous duty, the reserve up to 460 l/min absorbs rapid traverse peaks
- Up to 350 bar operating pressure, suitable for press circuits running at high system pressure
- Spool Symbol W8 with a linear characteristic, 3 switching positions
- Internal pilot oil supply with external pilot oil return, pilot operated design
- The control electronics sit on the valve body, position feedback makes a separate amplifier card unnecessary

Applications
This behaviour is wanted wherever an axis is moved by hand or a cylinder has to be unloaded at standstill, for example in setup mode and maintenance positions. FKM seals take higher temperatures than NBR. Pilot supply is taken internally, the drain is routed externally.
