Hydraulic actuator controls flow without signal from a central unit

A customer does not want to add onsite wiring and is looking for a stand-alone device that does not need to have the instructions transmitted from a central unit.
A customer can only use explosion-proof devices.
Sufficient reliability for frequent operation is necessary.
A customer needs low-cost maintenance.

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

Hydraulic actuator with stand alone control

Independent self-control actuators with the input signals converted from the fluid pressure of a plant (several kPa to several MPa).No control signals from a central unit are required and only the manual setting of pressure is necessary.
Utilizes electronic devices, thus allowing it to be used in explosion-proof environments through merely replacing the motors.
The independent self-control results in high reliability being maintained even when the actuators are very frequently used.
Simple mechanism and easy maintenance.

No on-site signal wiring work are required, thus reducing the cost of the wiring.
Improved installation environment by customer unnecessary, thus can ultimately reduce excessive running costs.
Maintenance and running costs are reduced as the parts are extremely durable even with highly frequent use.

5 to 6 months are necessary from accepting an order to shipment, although it does depend on the specifications and stock of necessary parts.

Determine the type of butterfly valve and hydraulic controller: Separate or integrated type needs to be known as soon as possible.
Determine whether vertical or horizontal piping is to applied as soon as possible.
Clarify the link length.
Clarify the flow direction of the fluid.
Clarify the maximum operation torque of the butterfly valve.

Major applicable fields

Actuators of this type are widely used in palm oil plants and sugar plants outside Japan (for example, in Indonesia and Myanmar). The reasons being that no on-site wiring work is required, and they are have excellent environmental resistance and easily maintained.
