Product Advantage
The disc cone pin is positioned tangentially, half in the disc and half in the shaft, making it in compression rather than shear, which eliminates the possibility of failure.
The rocker-shaped gland bridge compensates for uneven adjustment of the gland nut and reduces packing leakage.
Integral cast disc position stops perfectly position the disc in the seat for maximum seat and seal life.
Double eccentric configuration, reliable sealing performance, ensures that the valve disc will not contact the sealing seat when starting, solves the problem of uneven load on the sealing seat, prolongs the service life, and has the advantages of high temperature resistance, wear resistance, corrosion resistance, etc., ensuring reliable sealing performance.
Small size, light weight, easy installation and maintenance.
Double eccentric butterfly valve is also called high performance butterfly valve. It is mainly used for the drainage of water plants, power plants, iron and steel plants, chemicals, water source projects, environmental facilities construction, etc. It is especially suitable for water supply pipelines as adjustment and cutting equipment.
Compared with the centerline butterfly valve, the double eccentric butterfly valve is more resistant to high pressure, has a longer life and better stability. Compared with other valves, the larger the diameter, the lighter the material and the lower the cost. But because there is a butterfly plate in the middle, the flow resistance is large, so the butterfly valve smaller than DN200 is of little significance.
