The most common type of valve used to control intake and discharge lines from a pump is the ball valve. Ball valves are favored in these applications due to their excellent sealing properties and ability to provide a tight shut-off when fully closed. This design ensures that there is minimal leakage, which is crucial when handling fluids in pumping systems.

Additionally, ball valves can quickly open or close with a simple quarter turn of the handle, allowing for efficient control of the flow of fluids, which is essential for the operational efficiency of pumps. Their robust construction also makes them suitable for the high-pressure environments often encountered in pump systems.

Other valve types, while they each have their specific uses, may not offer the same combination of fast operation and reliability for intake and discharge lines. For instance, clapper valves are generally used for preventing backflow rather than controlling flow, while gate valves, although effective at fully opening or closing, do not have the same quick response and are prone to wear over time if used in throttling applications.
