Pipe network resilient seat seal gate valve

Classification：

Summary

Gate valve is one of the most widely used valves in all kinds of fluid conveying engineering.In traditional gate valves, there are many problems such as easy leakage of fluid and serious corrosion of internal parts.The common soft seal gate valve on the market is easy to leak at the stem shaft seal and the sealing ring cannot be replaced under the condition of constant water and any opening degree.
