Quarter-Turn Actuators

Quarter-Turn Marine Electric Valve Actuators

For Butterfly & Ball Valves

Quarter-Turn Actuators rotate a valve stem through 90 degrees to operate valves such as ball, butterfly, or plug valves. They convert an input signal (electric, pneumatic, or hydraulic) into mechanical motion, enabling precise control over valve positions.
