Desulfurization stainless steel butterfly valve structure design essentials 1 butterfly valve operating mechanism selection flexibility; 2 butterfly valve appearance beautiful corrosion resistance. 3. The butterfly valve with neutral structure without eccentric design, with significant characteristics of low operating torque, electric device configuration when the economy is significant; 4. Reasonable design, compact structure, easy installation and removal, easy maintenance; 5. The use of Lining structure, the disc sealing surface precision machining to a high finish, the friction coefficient of the rubber valve seat is very low, the valve life is longer; 6. The sealing surface of the valve plate flow characteristics of a linear state, with smaller Of the flow resistance coefficient, the valve flow resistance is small; 7 desulfurization stainless steel butterfly valve unique design of the molded rubber seat with excellent balance and support, effectively avoid the force caused by the rubber damage, the valve at the fully closed position Rubber is in the best compressed state to maintain zero leakage; 8. Valve port rubber sealing surface protruding ductile iron flange face, the valve in the pipeline installation without additional rubber gaskets.
