1. Small space occupation: Compared with the open stem gate valve, the concealed stem gate valve stem only moves inside the valve body and does not require additional space above the valve, so it is more suitable for installations with limited space.
2. Lower cost: Ductile iron gate valves are generally more cost-effective than rising stem gate valves. The simpler design and structure of concealed stem valves reduces manufacturing costs.
3. Can be used as an underground gate valve: Because the stem of the concealed stem gate valve is not exposed to the air, it can be suitable for underground applications, such as water distribution systems and underground pipelines.
4. Low maintenance requirements: Compared with rising stem valves, concealed stem gate valves do not have a rising stem outside the valve body, which means there are fewer moving parts that need maintenance or lubrication, thereby reducing the need for regular maintenance.
