1.Adopt the most advanced double eccentric sealing structure, reliable sealing performance, can achieve zero leakage.
2.Novel design, reasonable, unique structure, light weight, quick start.
3.Easy to operate, labor-saving dexterity.
4.Can be installed in any position, convenient maintenance
5.Seals can be replaced.  Reliable sealing to achieve two-way sealing zero leakage.
6.Sealing material aging resistance, corrosion resistance, long service life and other characteristics.
7.The stainless steel shafts are completely enclosed by O-ring sealing. This protect the whole bearing optimally from corrosion.
8.Upper and lower shaft design, flow resistance lightly, blow-out proof shaft design.
9.Wear-resistant, anti-corrosive and impermeable safe seat.
10.The rubber sealing profile retains the rubber sealing ring sturdy between the disk and the retaining ring.
11.No risk that the sealing ring will be pulled out even at high gap flow speeds.
12.Considerable reduction of the shear stress on the sealing ring.
13.High service life due to low wear on the sealing ring.
14.High sealing force and low operating torque.

Application

Double-offset flanged butterfly valve, available with long or short face-to-face length for use in most common flow control applications. Long service life, as the media does not come into contact with the bearing, and due to the wear-resistant, corrosion and infiltration-proof seat with weld overlay. Suitable for use water distribution, water treatment, pre-treated waste water, dams, power plants, industry and pressure management.
