Gate valves are of generally two types- Rising stem and non rising stem gate valve. Rising stem gate valves have the threads external to the valve body. You can see the valve stem is moving up when the valve is opening. In this way, you can visually keep track of how far the valve is open. Non-rising stem gate valves have threads that lift the gates are exposed to the fluid being controlled by the valve.
