A stop valve is any sort of valve system that totally stops the flow of liquid through a pipe. There are many styles of stop valves, but two of the most common are gate valves and globe valves. Gate valves don’t restrict flow when not in use, but they take longer to move into position and are more likely to leak. A globe valve will interrupt flow at all times, but will move into position very quickly. Both of these valve types are common on piping systems of all shapes and sizes.
