Direct Operated Type Directional and Flow Control Valves

Transcription

1 Specifications igh Response Type Proportional Electro-ydraulic Directional and Flow Control Valves igh response, high precision and high reliability are achieved be a combination of a compact and powerful solenoid and a spool-position-detection LVDT. Direct type ELDFG-/3 and two stage type ELDFG-/6 (which use the ELDFG- as a pilot) are available. Direct Operated Type Directional and Flow Control Valves 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. Description Model No. Max. Operating Pressure MPa (PSI) Max.
