Double Flanged Butterfly Valve using the same material into the valve body seals, the applicable temperature varies depending on the selection valve, nominal pressure ≤ 10.0MPa, generally applicable to industry, metallurgy, environmental protection, regulating media flow conduit for ventilation purposes.
Series - 150 To 600
Design Features
- Novel design, reasonable, unique structure, light weight, open and close quickly
- Operating torque is small, easy to operate, smart victory
- Using materials adapted to meet different medium temperature and corrosive media
- PTFE Lined Wafer Resilient Seated Butterfly Valve is bi-directional flow and possible at maximum operating pressure and because of valve port is corresponds to the piping diameter, high flow capacity is guaranteed
- Easy to open and close quickly, labor saving, fluid resistance is small, can often operate
