4WRKE | Pilot-operated proportional directional valve with displacement feedback
• Cost-effective
• High repeatability
• Spools with multiple specifications
The 4WRKE series is a higher-grade pilot-operated 3-position 4-way proportional directional valve compared with the 4WRZ(E) series. It features a wider nominal flow range of 50–600 L/min (at a pressure differential Δp = 5 bar per side). Equipped with integrated electrical position feedback and a digital amplifier, it delivers stable and reliable control performance, and is widely used in industrial hydraulic systems.
4WRKE Key Technical Features
High Cost Performance
It boasts better performance than the 4WRZ(E) series, nearly matching the 4WRTE series, yet priced far more competitively than the 4WRTE.
High Repeatability
Its repeatability reaches 0.2%, making it ideal for applications demanding high repeat positioning accuracy of hydraulic cylinders.
Multiple Spool Specifications
A wide range of spool options are available (including various center functions, flow characteristics and multiple working positions) to accommodate diverse operating conditions.
