The valve working with actuator is well known to be a device for closing and opening the valve. Manual valves must be adjusted by the direct or gear mechanism mounted on the stem of the valve. Use pneumatic, hydraulic, or electric actuators to remotely adjust valves or operate large valves quickly. Electric valve actuators can be the last element of the automatic route to automatically adjust flow, level or other processes. The actuator simply opens and closes the valve and can also tolerate the intermediate position. Some valve actuators include switches or other methods for remotely indicating the position of the valve.KP-LOK

Actuators for industrial valve automation can be used in all treatment facilities. They are used in wastewater treatment plants, power plants, refineries, mining and nuclear processes, food plants and pipelines. Valve drivers play an important role in automating process control. Automatic valve design and size are different. The valves vary in diameter from 1/10 inch to several feet.

What does the valve do?

In many applications it is important that the actual value is the same set point value is applied, the actuator is attached to the valve, to perform pressure control and flow control. This motor box can use pneumatic or electric current. It then converts this energy into motion and modifies or moves the position of the valve to maintain the actuator set point input.

There are four types of actuators: manual, hydraulic electric and pneumatic. The main work of the valve is to control the flow of liquid or gas in the pipeline. There are a variety of types of valves, each of which is unique, but the ultimate basic principle is the same. Some of the most common types of valves are two-way and three-way valves, which operate with pneumatic, electric or hydraulic oils.

What does this actuator do?

The actuator is a counter built into the valve body that is indicated when the valve is opened and closed using the control system. As with valves, you can choose from many types of actuators depending on the application you are using. Some examples of types of actuators include manual linear actuators, rotary actuators, and hydrodynamic rotary actuators.


What is the difference between a valve and an actuator?

As shown, the valve and the actuator are two completely separate components. However, they work together to do a common job. Thus, it can be said that the valve is opened and closed by a physical part of the system to indicate an actuation amount of the transfer valve of the fluid valve.

For example, in a floor heating system, fluids of different temperatures are pumped under the floor structure and used to maintain a preset temperature. The system is only suitable for valves, but the function of the valve cannot be controlled except for manual methods. This means that humans must constantly monitor the soil temperature and adjust the valves when they need to be changed. However, if the valve is installed with the actuator, the actuator can be configured to open or close the valve, or a computer controller that meets certain criteria used at a given time, the reference value of the temperature of the valve.
