What type of valve would you install to isolate a dual pressure device while keeping the system operational?

In the context of isolating a dual pressure device while maintaining the operational state of the system, a stop valve is the most appropriate choice. A stop valve is designed to provide a means of quickly and effectively controlling the flow of fluid in a pipeline or system. It functions by completely opening or closing the flow path, allowing for isolation of specific equipment or sections of the system without disrupting the entire operation.

The ability to isolate a device while keeping the overall system operational is crucial in many operational scenarios, such as performing maintenance on equipment or troubleshooting without interrupting overall system processes. Stop valves are particularly valued for their straightforward operation and reliability, making them ideal for such tasks.

While ball valves also serve the purpose of controlling flow and can provide a similar ability to isolate devices, they are typically used in applications where a quick on/off operation is required, and their design may not always be as effective for precise flow regulation in all situations.

Check valves are designed to allow flow in one direction and prevent backflow, but they are not built for isolation purposes, as they cannot completely stop flow in both directions.

Safety valves are crucial for overpressure protection in systems, allowing for the release of excess pressure, but they do not serve the purpose of isolating devices in
