What is the advantage of fully lined butterfly valve?
The main advantage of lined butterfly valve is that it can handle abrasive and corrosive application at a relatively lower cost.
The PTFE or PFA flexible seat provide a zero leakage sealing performance.
Plus, the lined material PTFE has strong corrosion resistance, stable performance, low friction coefficient, which make the lined butterfly valve has a long service life.
How does Dervos control quality of raw material?
Raw material plays an important role in product quality. Likewise, casting and forging affect valve quality a lot. That is why Dervos pay a lot of attention to foundries. We have an approval list of foundries and classify them by certificates, scale, process and materials. To meet different requirements from customers, we could even appoint suitable foundries for our customers.
