Extended stem gate valve, also known as directly buried gate valve is a gate valve with a special design of the length of the operating stem, mainly used in piping systems that need to be buried deep underground.

Underground Extended Stem Gate Valve usually consists of valve body, valve cover, valve stem, valve seat, valve flap and extension stem. Extension stem is a special design realized by adding length to the valve stem. When an extension stem gate valve is installed deep underground, devices such as operating handles or gears can be raised to a position where they can be easily operated by means of the extension stem. The valve flap realizes the opening and closing of the valve by the lifting and lowering movement of the stem.
