Product Overview
The triple-eccentric flanged butterfly valve stands out in the modern industrial fluid control field with its superior regulation performance and sealing reliability. It adopts advanced eccentric principles and sealing technology, effectively reducing friction between the valve disc and seat through three precisely designed eccentric structures, thus ensuring long-term durability and stability. This butterfly valve not only boasts excellent mechanical properties but also enjoys wide applicability, meeting the fluid control needs of various industries such as petroleum, chemicals, natural gas, power, metallurgy, heating, and water supply. It can handle media including but not limited to water, oil, steam, acidic or alkaline fluids.
TAIYI butterfly valve adopts the design of top flange yoke as standard ISO5211. It is more beautiful, and also convenient to assemble the actuator.
