Innovative set of electric ball valve

Electric Ball Valve made great progress over the past few years, the performance and acceptance. But until recently, one area, they rarely use: regulation and control, in the air force, the diaphragm drive units hold the highest rankings. But this is changing, such as the electric actuator seems ready to take over another area.

Valve actuator in the power industry has maintained a place of isolation. Main steam stop valve and other important historical Electric Ball Valve. However, until the arrival of the latest technological advances, the traditional control of Electric ball valve actuators are usually used for modulation of the pneumatic spring diaphragm.

In the past, there have been several attempts to plant in the design of all electric drive, but the constant experimentation in terms of the limitations of the electric actuator position and not to capacity, has proven to be an insurmountable obstacle to overcome.

However, there are some applications that drive electric actuators have been successfully replaced by air. For example, damper control, usually electric or hydraulic cylinder valve cylinder drive, and often continue to adjust capacity and electric actuator.

Control valve constantly moving, with the main controller set point from. A typical electric actuator design is not a constant adjustment. Gear wear and overheating will cause the motor. Today, however, the new technology in the motor control motor and drive train combined with carefully selected to overcome this.

In the past, another obstacle with the valve actuator has lost its power to control the lack of an elegant way to drive the ideal valve position control. With the diaphragm drive pneumatic valve springs, there is always a default position of failure. Therefore, the traditional process engineers accustomed to using this approach to their design.

Up to now the only way to drive the electric actuator is the location of a failure, until a battery is not the right solution. Prince asked 3 times the size of the electric motor requirements, otherwise, the battery can not provide enough power to quickly provide the necessary rapid shutdown of the electric actuator spring end of the copy.

There are many small electric actuator adjustment, but the degree of regulation varies from manufacturer to manufacturer. S9, and very few are able to achieve the Independent Electoral Commission 34, 100% of the regulation. The cost of buying the drive power when compared to the cost of ownership is insignificant. Perhaps the most relevant electric valve actuators cost of production loss due to misuse of electrical equipment to the low efficiency caused by the inaccuracies, or even failure. http://www.china-ballvalve.cn/Electric-Ball-Valve.html
