【Product Specialty】:

1. LUG Double Offset Butterfly Valve is equipped with an eccentric tilting conical seat seal for low frictional resistance when squeezing the sealing surface. 

2. The special geometry makes the butterfly valve without other butterfly frame unsealed defects will be over-opened, thus ensuring a good surface seal.

3. The double eccentric butterfly valve structure can ensure that the valve is normally in a high pressure state, and overcomes the shortcomings of other valves which are easily leaked due to deformation when working under high pressure.
