2、 Detailed information
Product Overview
Double eccentric butterfly valves, also known as high-performance butterfly valves, have a structural feature that the valve stem axis deviates from both the center of the butterfly plate and the center of the body. They adopt an elastic pressure self-sealing valve seat structure, which can achieve lower torque. They are mainly suitable for cutting and regulating drainage in water plants, power plants, chemical systems, and other systems.
Design and inspection can comply with standards such as API 609 and GB/T 12238.
main features
① Double eccentric structure with tighter sealing function, reliable sealing performance
② The sealing pair material is made of stainless steel and rubber, with a long service life
③ The rubber sealing ring can be located on the valve body or on the butterfly plate, suitable for different media characteristics, for users to choose from
④ The butterfly plate adopts a frame structure with high strength, large flow area, and low flow resistance
⑤ The valve has a unique structure, flexible operation, labor-saving, and convenient operation
