I would like to ask about the difference between valve rubber linings and rubber coatings

D71j or D71x: according to the valve manual, the letter J indicates that the lining is made of plastic, while x indicates that the lining is made of rubber. What is the difference between them?

The D71J has its valve chamber and butterfly disc lined with rubber, while the D71X has rubber only on its sealing surface

D71J rubber lining covers the valve body as well as the disc entirely with rubber. These are generally used in corrosive media. And D71X refers to rubber sealing. It’s just what we call a soft seal. Such general media tend to have a lot of water flow. This price is also much cheaper.
