The design of the concealed stem gate valve converts operating torque into operating thrust. When the valve is opened, when the lifting height of the gate is equal to 1:1 times the valve diameter, the fluid channel is completely unobstructed. The concealed stem gate valve has good sealing performance and is suitable for various pipeline systems, especially in situations where full opening and full closing are required. Hidden stem gate valves are usually connected by flanges. When selecting concealed gate valves, it should be noted that their specifications and categories should comply with the pipeline.
