For manifolds with an existing pilot plate, fully external pilot oil routing is the simplest answer. The 4WRKE32W8-600L takes both pilot supply and pilot return from outside while metering 600 l/min of nominal flow at 350 bar. Command value ±10 V, mass 37.22 kg.

Where the manifold already carries its own pilot oil channel, the valve should use it rather than open a second one. This version of the NG32 proportional valve works with external pilot oil supply plus external pilot oil return, setting 600 l/min of nominal flow from a ±10 V command value at operating pressures to 350 bar.
Benefits
- Pilot oil supply as well as pilot return run externally, matching pilot channels already piped in the manifold
- Nominal flow of 600 l/min with spool symbol W8, maximum flow 1600 l/min
- Operating pressure of 350 bar across 4 ports to connection diagram ISO 4401-10-09-0-05
- A ±10 V command value drives on-board electronics on 24 VDC with internal position feedback
- NBR seals for HL hydraulic fluid, installed mass 37.22 kg

Application
The classic case is extending existing control manifolds whose pilot circuit is already piped. With both pilot paths outside, pilot pressure can be adjusted plus filtered independently. Size 32 units of this kind serve press cylinders, forging plants as well as heavy test rigs.
