Socket End Resilient Soft Seat Gate Valves
Product Overview:
The main feature of socket end resilient soft seat gate valves is setting two sockets and pipes to form connection. Namely: insert the pipe into the sockets, the installation is simple,put the rubber sealing ring between the pipes and sockets to realize the seal.This connection is different from flange, it can be called flexible connection or stress free connection. The advantage is the permission of moderate flex pipes in socket connection,it has the compensation effect to the change of the length of the pipe, meantime , it removes the material stress in the pipes which were caused by expansion and contraction. This kind of valve has the outstanding advantage of overall rubber coating,anti-corrosion, nonbreakable, good elastic memory and long service life etc. It can be widely used on tap water, sewage, construction, food, electric power, medicine,metallurgy,light textile .energy system and other fluid on the pipeline as the adjusting and the closure device.
