Product Description:
Purpose:
The wafer butterfly valve that we produced is comprised of ductile iron body, EPDM seat, ductile iron disc, stainless steel shaft, etc. It’s corrosion resistant. The corrosion resistance is ten times that of ordinary products. It’s widely used because of simple structure, good performance and easy to install.
Rubber lined butterfly valve is a kind of valve with thick polymer lining on the body and disc.The lining makes the body completely isolate from medium and provides excellent anti-corrosive performance.It is designed as a device to shut-off or regulate the working medium flow and installed in pipelines or vessels with medium of acid,salt and oxidant ,reducing agent.or solvent in chemical,petroleum,pharmacy,food,iron and steel smelting,paper making,water power plant etc. it can be served,globe valves as well as other shutting off or regulating valves.
