Rising Stem Resilient Seated Gate Valves

  • Product Name:  Rising Stem Resilient Seated Gate Valves
  • Product Details:  Rising Stem Resilient Seated Gate Valves

Rising Stem Resilient gate valve (Rising Stem Resilient Seated Gate Valves)
Rising stem resilient gate valves not only has advantages of resilient seated ones has,but also can be seen for its intuitive opening and closing. It also featured in fast and reliable opening and closing thus it is widely applied in fire-fighting and industrial system and installed in a higher position from the ground.

Benefits and Features:
1. Rubber covered entirely:it is rubber covered entirely,which has advantages of good coverage performance and accurate dimensions to ensure reliable sealing and extended service life .
2. Light weight:the valve body is made by ductile iron,which is light weight and easily installed.
3. Flat seat:the base of it used flat type seat design,the same as pipeline,which do not produce sundry siltation and will seal more reliable.
4. Corrosion resistance:its lumen use non-toxic epoxy resin coating shape,which can prevent corrosion and rust.The rising stem soft-sealing valve not only can benefit you to drink raw potable water but also can be fitted in the sewage system.
5. Three ways“o”ring seal:valve stem, adapted three way “o”ring seal,has little friction resistance, light switch and remain no leakage.
