Rising stem gate valves have the threads external to the valve body. The gate valve stem is moving up when the valve is opening. Rising stem valves are usually made from cast or forged steel while non rising stem valves are more typically brass, bronze or cast iron.
Rising stem gate valves can be used in high pressure rating up to Class 2500 or up to 420 bar, while non rising stem gate valves are normally used for middle pressure rating.
In this way you can visually keep track of how far the valve is open. With a rising stem gate valve it is easy to tell if the valve is open or closed by looking at the amount of stem that is exposed. If the handle is flush with the pipe (no exposed stem), the valve is closed. If a lot of stem is exposed, the valve is open
