What is one advantage of using ball valves over tapered plug valves?

Using ball valves has the distinct advantage of being less likely to seize up compared to tapered plug valves. This reliability comes from the design of the ball valve, which features a smooth, rounded ball that rotates within the housing to control flow. This design minimizes the surface area in contact with the valve seat, reducing friction and the likelihood of wear and tear that can lead to seizing.

Tapered plug valves have a plug that fits into a tapered seat, and over time, debris or sediment can cause the plug to bind or seize, making operation difficult. The ball valve's simple mechanism allows for a more consistent performance over time, even in environments where contaminants may be present. As a result, the ball valve is often preferred in applications where long-term reliability and ease of operation are critical.

While the other choices highlight some qualities of ball valves—such as their ease of installation, larger diameter options, and repair simplicity—these factors do not consistently outline one clear advantage over tapered plug valves, which can be more prone to issues over time. Overall, the lower risk of seizing up is a significant benefit, especially in commercial food equipment settings where reliable valve operation is crucial for safety and functionality.
