What type of valve is a corporation stop?

• A. Ball valve or plug valve
• B. Butterfly valve
• C. Control valve
• D. Foot valve

Answer: (A)

A corporation stop is primarily associated with the connection of a water service line to a water main, and it serves as a shut-off valve for the service line. This type of valve is typically a ball valve or a plug valve. Ball valves operate by using a spherical disc (the ball) that rotates to either allow or block the flow of water, providing a quick and effective means of stopping flow. Plug valves function similarly but use a cylindrical or tapered plug with a hole through which fluid can flow. Both types offer reliable sealing capabilities and durability, making them well-suited for providing a tight shut-off in a corporation stop application. The other types of valves mentioned, such as butterfly valves, control valves, and foot valves, have different applications that do not align with the specific function of a corporation stop. Butterfly valves provide flow regulation and are commonly used in larger pipelines. Control valves are used to manage fluid flow and pressure within a system, often in response to control signals, while foot valves are designed to maintain prime in pumps by preventing backflow, which does not apply to the context of a corporation stop.
