What is the difference between a stop valve and a gate valve?
Stop valve, also called stop valve, is one of the most widely used valves. The gate valve is a gate with opening and closing parts. The movement direction of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted and throttled.
Do shut off valves go bad?
As time takes its toll on these trusted devices, they can become prone to failure. The most common failure found in an old shut-off valve is seizing. Another common failure is rubber stops or seals within the valve deteriorate and fail to abate the water flow completely.

Which is better a ball valve or a gate valve?
Ball valves are more effective at forming a tight seal and have more reliability and longevity than gate valves, but tend to be more expensive. They are often used for shutoff and control applications. Because ball valves can open and close immediately, they are more likely than gate valves to cause water hammer.
