Double eccentric butterfly valve design concepts into the design of ball valves

As the sphere of traditional ball always in contact with the sealing surface of the valve seat,  Stainless steel needle valves  process could easily lead to wear seat sealing surface of the sphere, causing the valve to produce the drain. To overcome this deficiency, the double eccentric butterfly valve ball valve design concepts into the design, the development of a new type of valve structure - single-seat double eccentric fixed ball. The series ball valve seal attached to the structure, mainly for the hydroelectric power  High pressure ball valve inlet end, the medium is water at room temperature for turbine maintenance or crew protection system failed to adjust drying time. The product can also be used for other transportation systems such as municipal water and oil. Hydraulic valve operation can be a heavy hammer, worm gear, electric, hydraulic and pneumatic form.
