Product Information

Electric Manual Return Type LTKD Series

This is a valve actuator that regards safety as important and gives priority to the field, because electric operation state can only be restored manually in order to prevent danger in maintenance or servicing. It is most commonly used in water-related systems, and highly regarded for durability, safety, and reliability.

Features

  • It is fully equipped with such safety mechanisms as a limit switch, a torque switch, and an interlock switch.
  • The adopted motor has such characteristics as are suitable for operability of the valve. Moreover, wiring is independent because the dedicated terminal box is included, thereby improving safety.
  • A safety device is incorporated in the handle section. Even if any abnormal force is applied during manual operation, it prevents breakage in the valve or the gate. (LTKD-05 type or later)
  • Since there are a wide variety of models, they can be used for many applications ranging from gate valves to gates.
  • Operation can be toggled between manual and electric easily with a single motion.
