Although most valves are manually operated, some use power operation. Why is this done?

• A. To increase manufacturing costs
• B. Size of the valve, Accessibility, To permit operation by instruments
• C. To reduce maintenance needs
• D. To comply with safety regulations

Answer: (B)

The choice that indicates the reason for power operation in some valves encompasses several practical aspects that are essential for effective system management. Power-operated valves are often utilized due to the size of the valve; larger valves can be heavy and difficult to operate manually, creating physical strain and making it impractical for frequent adjustments. The accessibility of the valve also plays a crucial role; if a valve is in a location that is hard to reach, power operation allows for easier engagement without the need for personnel to access cramped or potentially hazardous spaces. Another critical factor is the ability to integrate the operation of these valves with instruments, such as automated control systems. This can enhance responsiveness and precision in process control, allowing for more efficient operations and improved safety. Automated systems can also facilitate remote operation, which is particularly valuable in high-risk environments or where safety protocols dictate minimizing human exposure. Thus, the combination of these elements—size, accessibility, and instrumentation—constitutes a sound rationale for employing power operation, enhancing both the functionality and efficiency of the piping system components.
