OBE (On-Board Electronics) Type High Response Proportional Electro-Hydraulic Directional and Flow Control Valves (Two Stage Type) ELDFHG-04EH/06EH
High response, high precision and high reliability ELDFHG-04EH/06EH are achieved be a combination of a compact and powerful solenoid and a spool-position-detection LVDT.
These valves are closed loop, high response type proportional electro-hydraulic directional and flow control valves with OBE ( On board electronics)
This product can be interchanged with the simpliffied servo valve to perform position control and pressure control.
Compared to nozzle flapper type servo valve, this product has excellent contamination-related problems.
