Hydraulic actuator of easy maintenance and operational direction changes, and very energy efficient

  • A customer wants to contribute to the energy and resource conservation that are the global issues of today, even if only in a small way.
  • A customer wishes to reduce the necessary cost and facility shutdown period by reducing the time needed for maintenance.
  • A customer is seeking an actuator with high accuracy control to achieve more effective facility operation .
  • The method of operating the facility has yet to have been decided, changes will be required after delivery, and extensive modification of the installation site will be necessary.

Our HOP series actuators are the most suitable for use in resolving the above problems!

  • The actuator requires only a small amount of power because a power saving system is activated during any non-actuating periods.
  • The energy saving mechanism reduces the deterioration of the hydraulic oil due to unnecessary increases in temperature and thus ensures a longer replacement cycle (every other year recommended).
  • Maintenance can be done quickly because an upper manhole allows maintenance access for replacing the suction filters etc.
  • The deviation between the input signal and feed back signal detected by the potentiometer is calculated by an amplifier. The arm rotates continuously when the deviation is large but intermittently when the deviation is small. This then allows very fast but highly-accurate positioning.
  • Rotation direction and opening degree signal can be reversed using a single switch.
  • Less electricity and hydraulic oil consumed.
  • Less maintenance and running costs than before.
  • Facility operation and operability of customer's site improved with more accurate performance.
  • Customers can easily change the rotation direction and open degree signal direction onsite.

Two to three months from order to shipment are necessary depending on the specifications and necessary parts.

Hydraulic actuator with excellent responsiveness
  • Determine the type of butterfly valve and hydraulic controller: Separate or integrated type needs to be known as soon as possible.
  • Clarify the link length.
  • Clarify the maximum operation torque of the butterfly valve.
  • Determine the necessity for emergency operation with an accumulator as soon as possible.

Major applicable fields

Our actuators are mainly used in controlling the pressure of blowers and preventing surges at sewage treatment facilities, disposal facilities and cement plants because of their various benefits that include excellent environmental resistance, less deteriorative parts, and stability in operation.
