Actuated or Manual Valve: Which One to Choose?

When it comes to controlling the flow of fluids in a pipeline, valves play a crucial role. Valves are devices that regulate the flow of fluids by opening, closing, or partially obstructing the passage of fluids. There are two types of valves: actuated and manual valves. In this post, we will discuss the differences between these two types of valves and help you decide which one to choose for your application.

Actuated Valves

Actuated valves are valves that are operated by an external power source, such as an electric motor, pneumatic actuator, or hydraulic actuator. These valves are ideal for applications where precise control is required, or where the valve needs to be operated remotely. Actuated valves are commonly used in industries such as oil and gas, chemical, and water treatment.

One of the main advantages of actuated valves is that they can be controlled remotely, which means that they can be operated from a control room or a remote location. This makes them ideal for applications where the valve is located in a hazardous or hard-to-reach area. Actuated valves are also more precise than manual valves, which means that they can provide better control over the flow of fluids.

Manual Valves

Manual valves, on the other hand, are valves that are operated manually, either by turning a handle or a wheel. These valves are ideal for applications where the valve needs to be operated infrequently or where the valve is located in an area where there is no power source available. Manual valves are commonly used in industries such as agriculture, mining, and construction.

One of the main advantages of manual valves is that they are simple and easy to operate. They do not require any external power source, which means that they can be used in remote locations. Manual valves are also less expensive than actuated valves, which makes them ideal for applications where cost is a concern.

Which One to Choose?

The choice between actuated and manual valves depends on several factors, such as the application, the environment, and the budget. If precise control is required, or if the valve needs to be operated remotely, then an actuated valve is the best choice. If the valve needs to be operated infrequently, or if there is no power source available, then a manual valve is the best choice.

In conclusion, both actuated and manual valves have their advantages and disadvantages. The choice between these two types of valves depends on the specific needs of the application. By understanding the differences between these two types of valves, you can make an informed decision and choose the valve that is best suited for your application.
