Electric Auto Return Type LTMD Series

Automatically Changing Manual Operation State to Electric Operation State by Switch-On or Command from Remote Site

It is often the case that this is installed in a power, oil, gas, or chemical plant, and used as a stop valve for hot and high-pressure steam or high-pressure gas. Therefore, there is enough variation to support special types, such as an explosion-proof type and a heat-resistant type.

Electric Auto Return Type LTMD Series

Features

  • It is fully equipped with such safety mechanisms as a limit switch and a torque 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 sluices.
  • Operation can be switched from electric to manual easily with a single motion. Operation is automatically switched from manual to electric when power is fed to the electric motor.
