The LY actuator controls the opening and closing travel of the valve and limits torque through the torque
switches provided. As a result, all valve-operating parts are protected from overload, improper seating,
and foreign obstructions.
LY actuators may be mounted on any size valve in almost any position or location.
Microprocessor-based control and monitoring devices are available for installation on your actuator.
Contact your local Limitorque distributor or Limitorque sales office for further information.
