What Is Ball Valves?

There is a hollow ball inside the ball valve. The ball is driven by the valve stem and rotates around the stem of the ball valve.
The ball valve is mainly used to on-off, mix, diverter and change the flow direction of the medium in the pipeline. It only needs to rotate 90 degrees and a small torque can be closed tightly.
Ball valves are widely used in petroleum refining, long-distance pipelines, chemicals, papermaking, pharmaceuticals, water conservancy, electric power, municipal administration, steel and other industries.

What Is Automatic Actuators?

Automatic actuators are mechanical devices that could help us to control the valve remotely. Normally they are sourced by power, clean air, and control signal(4-20mA, 1-5VDC, 0-10VDC) to driven.

Features of automatic actuators are including intelligence, high production efficiency, saving labor costs, remote operation, and offer high-performance solutions for the automatic project.

Why We Need An Actuator?

Sometimes we will encounter industries with a harsher environment, such as explosion hazard, stormy weather, snowy weather and so on. At this time, in order to protect personal safety, the actuator is very necessary.
The actuator could help us remotely control, and through the control system, we can clearly know the valve’s opening and closing conditions and the flow control process. Therefore, the actuators could well help us protect personal safety.

At the same time, the actuator is very suitable for large-scale projects. Imagine that if a project has multiple valves and we need to manually open or close them one by one, it will take a lot of time and will affect our production efficiency.
Therefore, by receiving the signal through the actuator, we can realize remote one-key start the valve, save time, improve production efficiency, and obtain more profits.
