What is an advantage of using rotary valves?

Using rotary valves offers the advantage of being able to handle large pressure differences effectively. This is largely due to their design, which allows for a smooth transition of flow and minimizes turbulence. In applications where there are significant fluctuations in pressure, rotary valves can maintain operational efficiency without being compromised by the pressure changes. Their ability to manage this aspect makes them particularly suitable for various utility applications where pressure control is critical.

While other choices highlight different benefits—like the simplicity of design, high flow rates, and compactness—these do not directly address the pivotal function of rotary valves in pressure management. The key takeaway is the importance of understanding the operational demands of a system and how rotary valves can meet those challenges effectively.
