Description
Our double eccentric butterfly valves are designed for superior sealing performance, reduced wear, and extended service life. Featuring an offset disc design, these valves minimize seat contact during operation, resulting in lower torque, less friction, and improved durability in demanding industrial applications.
Size Range: DN50 to DN2400
Pressure Rating: PN10 / PN16
Construction & Materials:
- Body Materials: Ductile Iron (DI), WCB, CF3, CF3M, CF8, CF8M
- Disc Materials: DI, WCB, CF3, CF3M, CF8, CF8M
