Electric actuator valves

The Shuangda Valve (SDV) Company Motor Operated Valves (MOV) family of valves are an important item of Plant & Piping system. These valves are generally of large size and are used for different applications such as pump discharge etc. Motor Operated Valves are often called as On-Off valves as the motors serve the purpose of fully opening or fully closing valves in pipelines. For example, cooling water lines, process pipelines where regulation of fluid is not required, motor operated valves can be used to fully allow or fully stop the fluid flow. These valves are not used for throttling or precise control / regulation purposes as they serve mainly On-Off service application. Motor operated valves can be of various types e.g. Gate/ Ball/ Butterfly etc. with actuator control.

Motor operated valves, also known as MOVs, are a type of valve that are controlled by an electric motor rather than a manual handle or lever. These valves can be opened or closed remotely, and they can also be programmed to open or close at specific times or in response to certain conditions. This allows for precise control and automation of various industrial and commercial processes.

Motor operated valves are commonly used in a variety of applications, including water treatment plants, HVAC systems, and process control systems. They are also used in the oil and gas industry, power plants, and chemical processing plants. The use of motor operated valves in these applications allows for greater efficiency, safety, and cost-effectiveness.

One of the main benefits of motor operated valves is their ability to provide precise control over the flow of fluids or gases. This is achieved by using a feedback mechanism that allows the electric motor to adjust the position of the valve based on the flow rate of the fluid or gas. This allows for fine-tuning of the flow rate, which is important in applications such as chemical processing, where precise control is essential.

Another benefit of motor operated valves is their ability to be remotely controlled. This allows for the valves to be operated from a central control room, rather than having to manually operate each valve on site. This can be particularly useful in large industrial facilities, where it may be impractical to have someone physically present at every valve. Remote control also allows for the valves to be operated remotely in emergency situations, such as when a leak is detected.

Motor operated valves can also be programmed to open or close at specific times or in response to certain conditions. This allows for automation of various processes, which can improve efficiency and reduce the need for manual intervention. For example, a motor operated valve in a water treatment plant can be programmed to open at a certain time to release treated water into a storage tank, and then close again when the tank is full.

The use of motor operated valves can also improve safety in industrial and commercial applications. For example, in the oil and gas industry, motor operated valves can be used to control the flow of dangerous gases. If a manual valve were to fail, the gas would continue to flow, potentially causing an explosion. However, with a motor operated valve, the flow can be quickly shut off in the event of a failure, reducing the risk of an explosion.

In addition to their many benefits, motor operated valves are also relatively easy to install and maintain. They are typically designed to be compact and easy to access, which makes them easy to install in tight spaces. Many motor operated valves also have built-in diagnostic systems, which can help to quickly identify and resolve any issues that may arise.

Despite their many benefits, motor operated valves do have some limitations. One limitation is that they require a power source, which can be a problem in remote locations or in the event of a power outage. Additionally, motor operated valves can be more expensive than manual valves, which may be a concern for some applications.

Overall, motor operated valves are a valuable tool for precise control and automation of various industrial and commercial processes. Their ability to provide precise control over the flow of fluids or gases, be remotely controlled, and be programmed to open or close at specific times or in response to certain conditions make them ideal for a wide range of applications, including water treatment plants, HVAC systems, and process control systems. Additionally, the use of motor operated valves can improve safety and reduce the need for manual intervention in industrial and commercial applications.
