Series - 150 | PN10-PN16
Wafer or lug style for 150 class flange, F46 Lined Wafer Butterfly Valves features ease of maintenance, repeatable on-off, long life durability. Teflon Lined Wafer Butterfly Valve.
Design Features
- Full diameter structure, to ensure the flow area of the valve, to see the flow resistance when the fluid through the valve
- The butterfly plate adopts butterfly streamline design, which can ensure the stress intensity of the center of the butterfly plate, and also ensure that the valve can obtain a large flow coefficient and a small fluid resistance coefficient
- Simple structure, small flow resistance
