Concealed gate valve:
The height of the gate valve always remains unchanged, so the installation space is small, which is suitable for gate valves with large diameter or restricted installation space.
Open stem gate valve:
The fluid resistance is small, and the sealing surface is less scoured and eroded by the medium. Less effort to open and close. The medium flow direction is not restricted, does not disturb the flow and does not reduce the pressure. Simple shape, short structure length, good manufacturing process and wide application range.
