摘要

A direct drive servo valve including a motor having a shaft terminating in an engagement member. The engagement member is received within an opening defined by an engineering plastic material which is coupled to a valve member. The valve member is caused to reciprocate by rotation of the shaft of the motor to control the flow of fluid underpressure from a source thereof to output ports which are in turned coupled to a load.
