CF8M Disc PTFE Seat Flanged Butterfly Valve
Basic Info
- Ductile iron: has high tensile strength, wear, and temperature resistance. It ensures long-lasting performance and corrosion resistance. so it it a best material for soft seat butterfly valve.
- Soft valve seat: EPDM has good sealing and wear resistance, and can achieve zero leakage.
- Replaceable soft seat: When the valve seat wears, it affects use. This type of seat can be replaced without damaging the valve body. It makes maintenance easier, extends the valve’s life, and cuts maintenance costs.
- The double flange design makes the soft seat butterfly valve easy to install. It suits various pipeline systems, including pipeline end systems.
