Product Features the pipe is directly inserted into the socket, so the installation is very convenient, and the rubber sealing ring is placed between the pipe and the socket to realize the sealing. This kind of connection is different from flange connection, which is called flexible connection or stress-free connection. Its advantage of socket weld soft seat gate valve is that it allows the pipe to have an appropriate amount of expansion and contraction at the joint with the socket, which can compensate the length change of the pipe and eliminate the material stress caused by thermal expansion and cold contraction of the pipe. In order to protect the pipe, socket weld soft seat gate valve is suitable for urban water supply and drainage network.
