What are the two main types of valves used in utilities maintenance?

The two main types of valves used in utilities maintenance are rotary and linear valves. Rotary valves control the flow of fluid by using a rotating mechanism to open or close the passage. This type of valve is frequently employed in applications where space is limited and precise flow control is necessary. Linear valves, on the other hand, utilize a sliding motion to open or close the flow path. They are commonly used in applications where precise control over the movement of fluids is crucial.

Both rotary and linear valves play a vital role in the management and regulation of utilities infrastructure, ensuring that flows can be effectively controlled for various operational needs such as water supply, waste management, and other utilities services. Understanding the distinct functionalities and applications of these valve types is essential for maintenance workers, as it enables them to select the appropriate valve for a given task and ensure efficient operation within utility systems.
