Butterfly valves are quarter-turn valves that utilize a circular disc to regulate fluid flow. The disc, mounted on a rotating shaft, can be turned to open or close the valve. High-performance butterfly valves (HPBs) elevate this basic design through advanced materials, sealing technologies, and engi
I. Design Principle of Triple-Eccentric Butterfly ValveThe triple-eccentric butterfly valve has achieved a technological breakthrough in the field of sealing performance. Its core mechanism relies on the design of three innovative eccentric structures.First Eccentricity: By offsetting the centerline
Overview of API 609 and ASME B16.34 Standards API 609 StandardDeveloped by the American Petroleum Institute (API), API 609 specifies the design, manufacturing, and testing requirements for butterfly valves. This standard covers various types of butterfly valves, including double-flanged, wafer-type,
I. Definition and Challenges of Extreme Working ConditionsExtreme working conditions usually refer to environments that exceed normal operating conditions, including high temperature, low temperature, high pressure, strongly corrosive media, high-flow impact, etc. These conditions impose extremely s
Design Standards for Butterfly ValvesKey Standards and SpecificationsSeveral international and national standards govern the design and performance of butterfly valves, especially those intended for extreme conditions. Some of the most relevant standards include:• ANSI/FCI 70-2: This standard specif
