Buy High Quality Flange Double Offset Butterfly Valve Manufacturers, Suppliers and Factory with Low Price
1.Introduction of Flange Double Offset Butterfly Valve
Milestone Valve Co. Ltd. is a manufacturer specializing in the production of valves. It independently designs, develops, and produces various industrial valves such as butterfly valves, gate valves, ball valves, and check valves; among them, the self-designed Flange double offset butterfly valve has greatly eliminated the structure Excessive squeezing and scraping between the disc and the valve seat can reduce the opening resistance, reduce wear, and increase sealing performance and service life; Flange double offset butterfly valve is mainly used in petroleum, metallurgy, water treatment, water supply and drainage and other fields.

3.Structural Features of Flange Double Offset Butterfly Valve
1) Flange double offset butterfly valve adopts double eccentric structure, which has a longer service life than the centerline butterfly valve;
2) Flange double offset butterfly valve uses a soft T-shaped multi-layer stainless steel sheet on both sides to form a sealing ring, which has the dual advantages of metal hard and soft sealing, and has zero leakage sealing performance regardless of low temperature and high temperature.
3) Flange double offset butterfly valve two-stage valve stem design increases the flow area and reduces the flow resistance;
4) Flange double offset butterfly valve is designed with a labor-saving device at the bottom of the valve stem, and the operating torque is smaller;
5) The structure length of the flange double offset butterfly valve conforms to the EN 558-1 20 series standard, and the actuator connection conforms to the ISO5211 standard;
4.Application Range of Flange Double Offset Butterfly Valve
Flange double offset butterfly valve is mainly used for drainage of water plants, power plants, steel smelting, chemical engineering, water source engineering, environmental facility construction and other systems, especially suitable for water pipelines, as regulating and intercepting equipment.
