POPU Valve: PTFE Lined Flanged Butterfly Valve
The flange butterfly valve has its own flange. During installation, the flanges on the valve are connected to the pipe flange directly with bolts, and the sealing face is resistant to wear.
This type of butterfly valve lining material is PTFE, acid and alkali resistance, various organic solvents, and PTFE has the characteristics of high temperature resistance and small friction.
