The types of flange butterfly valves mainly include the following:
Stainless steel flange butterfly valve: Made of stainless steel (such as 304, 316, etc.), it is tightly connected to the pipeline system through flange connection. It has a disc-shaped butterfly plate inside, which can rotate around its own axis to realize the opening, closing and flow regulation functions of the valve. Stainless steel flange butterfly valve has the characteristics of high strength and corrosion resistance, and is suitable for various harsh working conditions. It has good sealing performance, flexible flow regulation, and easy installation and maintenance.
Sealed flange butterfly valve: This butterfly valve has excellent elastic recovery and automatic compensation capabilities, and can form an effective seal between the valve stem and the shaft sleeve to reduce leakage problems caused by gap changes. Its sealing sleeve has a double sealing structure, which enhances the medium adaptability and reliability.
Eccentric flange butterfly valve: This butterfly valve has a unique design, uses fewer bolts during installation, and has a compact structure. It is suitable for installation scenarios that require a reduction in the number of bolts.
