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
