Valve actuator
AC motor for hydraulic gate (General-purpose characteristics)
Outline
This motor is compliant with the technical standards for dam and floodgate facilities (draft) and technical standards for hydraulic gates and penstock and uses the 70-type motor developed for hydraulic gates. The 70-type motor has a brake, Class B insulation property, and 30-minute rating and can be constant-rated if it is equipped with a fan.
It has humidity resistance and insulation-treated winding wire, and is equipped with a totally enclosed outdoor-type terminal box.
In addition, because a single unit is compatible with motors with different capacities, the desired and sufficient motor can be selected.
