POWERPACK AJ11 / AJ21 / AJ41

1. Mô tả powerpack AJ11 / AJ21 / AJ41

The Powerpack is an actuator that controls a load such as a valve.
As its output shaft performs rotary motions it is suitable for controlling a final control element of rotary type such as a butterfly valve.

The Powerpack is a kind of an electro-hydraulic actuator.
It is of the proportional positioning type and has a hydraulic work piston that is proportional to the electrical system, with the function of converting a DC electrical signal (DC 4-20mA) into a motion of the hydraulic work piston.
The Powerpack is of a structure that unitizes the current-hydraulic pressure converter unit, the hydraulic pump and the work cylinder, and it does not require external piping.

2. Đặc tính powerpack AJ11 / AJ21 / AJ41

• Usable as an actuator for various electronic controllers.
• The actuating speed is high and a large actuating force can be obtained because actuation is performed by using hydraulic pressure on reception of an electrical signal.
• Maintenance is easy and reliability is high because of a moving coil system incorporating a hydraulic jet pipe and a stable permanent magnet.
• As the casing serves as an oil tank and all parts are contained in the interior, no external piping is required.
