Double-Eccentric Flanged Butterfly Valve
Hebei Diefei Valve Co., Ltd.
Product overview
Eccentric disc construction for water-system isolation and control.
Diefei’s double-eccentric flanged valve uses an offset arrangement intended to reduce seat rubbing during operation. The description identifies a T-shaped disc sealing-ring construction and discusses short and long face-to-face alternatives. Buyers should specify one dimensional series and material combination, with the required pressure and shutoff acceptance test confirmed for the actual valve.
Selection points
- Specify flange drilling, short/long face-to-face series and nominal size.
- Confirm seal material, torque and required shutoff test.
