Product introduction
The valve disc is rubber-packed to get excellent sealing effect by the rubber’s resilient deformation.Non-rising resilient seated gate valve solves the problem in general gate valve such as leakage,rusting etc. and saves installation space.It is widely used in tap water in dustry,sewage treatment,shipping,construction,petroleum,chemicals,food,pharmacy,textile,electric power,metallurgy and energy system’s pipeline to adjust and shut off fluid.
