ELDFG-01/03 EH Series
The Yuken ELDFG-01/03 EH valve range is a closed loop, high
response proportional directional and flow control valve with
OBE (on board electronics), 2 series line up with a maximum
rated flow up to 80 l/min (@⊿P=1MPa).
The addition of OBE to the Yuken range of ELDFG valves which
with simple servo valve performance levels of high response, high
accuracy, reliability, newly developed strong compact solenoids,

closed loop control with spool position sensor and differential
transformer mean the range can now offer simple operation and
user friendliness due to the simplified wiring.
Both size valves include a zero lap spool (Spool Type 3C2P) in the
range, which is most suitable use as for position control and
pressure control.

Special Features
• Equivalent to simple Servo Valve of Response Characteristics
ELDFG-01EH80 Hz/-90°(±25Amplitude)
ELDFG-03EH50 Hz/-90°(±25Amplitude)
This valve can be interchanged with the simplified servo
valve to perform position control and pressure control.

• Simple Operation and User-Friendliness
With only 24VDC power supply and a command signal input,
the valves give a highly accurate and fast operation of your
hydraulic system.
• Excellent Contamination Resistance
The valve provides excellent contamination resistance due
to the powerful solenoids, and so reduces problems caused
by dirty oil and therefore reduces filtration costs.
