BS5163 DI No-rising stem gate valve gate valve

Introduction

Gate valve is one of the most widely used valves in various fluid transportation projects.In traditional gate valves, there are common phenomena such as fluid leakage and serious internal corrosion. Common soft-seal gate valves and stems on the market The shaft seal is easy to leak, and it is impossible to replace the seal ring under the condition of constant water and any opening.Yuming elastic seat seal gate valve adopts novel structural design, strict manufacturing technology and high-performance new materials, which overcomes the traditional gate seal failure. The internal parts, especially the gate plate, are easy to be corroded and rubber elastic. Suitable for domestic water system, water supply and drainage system, sewage treatment system, chemical fluid transportation system It can be used as a cut-off device on fluid pipelines in construction, urban environmental protection, petrochemical, pharmaceutical, food, metallurgy, textile, power and other industries (not suitable for throttling).
