Hydraulic actuator of high reliability and stable in explosion-proof environments

Explosion-proof devices are necessary.
A customer wishes to contribute to resource conservation and zero emissions, even if only in a small way.
Sufficient reliability for frequent operation is necessary.
A customer needs to maintain the operating position of the valve.

Our EOP series actuators are most suitable for use in solving the above problems!

Hydraulic actuator suitable for the explosion-proof environments

Motors, force coils, and position transmitters can be modified into explosion-proof designs for use in explosion-proof environments.
No electronic devices are involved and the input signals (4 to 20mADC) are input to a force coil, thereby ensuring high reliability is retained even in harsh environments.
Utilizes the jet pipe method and hence the actuator is less influenced by hydraulic oil contamination, thereby allowing the hydraulic oil to be used longer. The actuator therefore contributes to better resource conservation while reducing the amount of waste oil.
The jet pipe method enables a level of high reliability even if the actuator is very frequently used.
Excellent retention of the valve opening position is achieved through maintaining the pressure of the cylinder.

Improved installation environment by customer unnecessary, thus can ultimately reduce excessive running costs.
Achieves resource conservation and reduces waste oil.
Maintenance and running costs get reduced as the parts are extremely durable even with highly frequent use.
Excellent retention of valve opening position enables worry-free operation.

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

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

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.
