Socket type Resilient Seated Gate ValvesThe main characteristics of the Socket type soft-sealing gate valve is socket connection formed between two sockets at the valve`s end and pipes,Namely, the pipe is directly into socket , and seal ring is set between them, which is convenient to install.It is different from flanged connection, called soft connection or flexible connection, whose advantages are allowing moderate expansion to compensate pipe`s length and protecting pipes by eliminating pipe`s material stress produced because of [expansion caused by heat and contraction caused by cold"
