Description
Brief Introduction
General gate valve presents the phenomenon of leaking ad rusting., our elastic gate valve has already overcome general gate valve's disadvantage like seal bad, elastic fatigue, aging of rubber, rusting, etc. Elastic seat gate valves can achieve good sealing under the elastic deformation compensation action. It has the advantage of fast open, good sealing, long service life. It can be widely used in the pipe line of water supply, sewage, petroleum, chemical, food, medicine, light textile, electric power, ships, metallurgy, energy systems, to act as adjusting or cut off device.
