Globe valves used in process control systems

In process control systems, ball valves are commonly used for a variety of purposes. Here are some specific applications of ball valves in process control systems:

1. Flow control: Ball valves are frequently used to control the flow rates of fluids in process pipelines. They can be adjusted to allow smooth and precise regulation of flow, ensuring the desired amount of fluid is delivered.

2. On/Off control: Ball valves are often utilized as on/off valves in process control systems. They provide a quick and efficient shut-off or opening mechanism, allowing for reliable start-up and shutdown of processes.

3. Pressure control: Ball valves can be used to regulate and maintain optimal pressure levels in process control systems. By adjusting the position of the ball within the valve body, the flow rate can be controlled to achieve the desired pressure levels.

4. Diverting and mixing: Ball valves with multiple ports, such as three-way or four-way ball valves, are employed in process control systems to direct or mix fluid flows. These valves enable the redirection of fluid paths and facilitate the mixing of different fluids within the process.

5. Drainage and venting: Ball valves with drain ports or vent ports are used in process systems to allow for the removal of trapped liquids or gases. These valves provide an effective means for draining or venting equipment or pipelines.

6. Hazardous materials handling: In critical process control systems where hazardous materials are involved, ball valves can be selected for their excellent sealing capabilities. They ensure the safe containment and control of hazardous fluids, reducing the risk of leaks or spills.
