Full-Turn Actuator with Cylindrical Wedge Mechanism

  • R. V. RomashinEmail author

Features of existing designs of actuators of ball valves are considered. An essentially new type of actuator capable of rotating 360° is presented. Data on the torque and specific moment of the proposed full-turn actuator are presented.

Key words
