4WRTE | Pilot-operated proportional servo valve
• High-frequency pilot proportional valve
• High flow & high pressure
• Integrated digital control
The 4WRTE series is a pilot-operated 3-position 4-way proportional directional valve with higher frequency response than the 4WRKE series. Its pilot valve adopts a spool-and-sleeve structure. The main valve has a nominal flow rate of 25–1000 L/min (at a unilateral pressure differential Δp=5 bar) and a maximum working pressure of 350 bar. Equipped with integrated electrical position feedback and a digital amplifier, it is suitable for high-precision control applications including position, speed and force regulation.
High-frequency Pilot Stage
Higher frequency response and superior dynamic performance compared with the 4WRKE series.
High Flow & High Pressure
Nominal flow up to 1000 L/min at Δp=5 bar, with a maximum working pressure of 350 bar to meet high-power operating requirements.
Integrated Digital Control
Built-in digital amplifier and electrical feedback improve control accuracy.
Precise Multi-parameter Adjustment
Ideal for high-precision closed-loop control of position, speed and force.
