Electric actuators are the more advanced electric-driven valve products in the industry. Basically, electric actuators are provided. So what kind of classification do they have on the valve body ball core?
Let's take a look at the basic introduction of electric actuators. The electric actuator uses the ball core to rotate about the axis 90 to realize the opening and closing of the valve. It is mainly used to cut off or communicate with the medium. Of course, it can also be used to adjust and control the fluid. There are many types of electric actuator ball cores, and their types and structures can be roughly divided into the following types:
Stainless steel electric actuator
The elastic ball structure, the ball valve ball has elasticity, and its valve seat and seal are basically made of metal materials. Therefore, the toll does not rebound very much, the use of the pressure itself can not reach the sealed conditions, you must use external forces.
The fixed ball structure, the electric actuator ball does not move when it is under pressure, so when the medium is under pressure, the valve seat will generate pressure, so that the sealing ring is fixed on the ball to achieve complete sealing.
The floating ball structure, whose sphere is floating, can produce displacement and press tightly on the sealing surface in terms of the medium pressure acting on the valve, which can ensure the outlet end seal.
The above is part of the electric actuator ball core. From the current industrial automation industry, it is still very important for some control systems in the industry.
