The rising stem gate valve allows you to visually track how far the valve has opened. For a rising stem gate valve, it is easy to tell if the valve is open or closed by looking at the number of exposed stems. If the handle is flushed with the pipe (no outer stem), the valve is closed. If a large number of stems are exposed, the valve opens.
