Features: Longer life and good stability
Features:
Leflow is providing high quality Double-offset butterfly valve. We produce double eccentric butterfly valves with diameters ranging from DN100 to DN1200.
Double offset uses two separate offsets to achieve a bubble-tight. One of the offsets is the location of the valve shaft relative to the centerline of the bore. Another offset is between the centerline of the disc/seat sealing surface and the shaft.
This structure make the valve has following benefits:
1. Double Eccentric structure ensures low operating torques with zero leakage performance;
2. Inner and outer surfaces of the valve are coated with fusion bonded epoxy,and Its thickness can be adjustable;
3. Low moments are obtained by decreasing the friction through self-lubricating bushings;
4. Can bear high stretching stresses on the pipeline through the ductile iron body and disc;
5. High impact resistance.
6. Pressure loss is at minimum level by double shaft design.
7. Sealing gaskets fasten by bolt can be replaced at field condition;
8. With the o-rings on the bearing bushings, disc pin holes are protected against corrosion (Dry shaft);
9. Retaining ring is assembled to the disc with imbus bolts, the disc is protected against corrosion by placing o-rings under the bolts.
10. Stainless steel welding seat can reach better sealing
