High Response Type Proportional Electro-Hydraulic Directional and Flow Control Valves

Transcription

1 igh Response ype roportional Electro-ydraulic s igh response, high precision and high reliability are achieved by a combination of compact and powerful solenoid and spool-position-detection LVD. Direct type ELDFG-1/3 and two stage type ELDFG/6 (which use the ELDFG-1 as a pilot) are available. Direct Operated ype s his product can be interchanged with the simplified servo valve to perform position control and pressure control. Compared to nozzle flapper type of servo valve, this product has excellent contamination-related problems. EIC--17- Specification Description Model Numbers See Valve res.
