Description
Description:
SVA9-N electro-hydraulic converter is composed of moving coil force motor and slide valve hydraulic servo driver. Direct position feedback is adopted between the servo piston and the control valve core, so the weak electric signal can be converted into displacement output with considerable thrust after being amplified by electro-hydraulic servo. SVA9-N electro-hydraulic converter has the advantages of compact structure, sensitive response, high reliability, good dynamic characteristics, low requirements for oil cleanliness and simple maintenance. Therefore, it is widely used in the electro-hydraulic governor of hydro generator units.
