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,

1. Understanding Wafer Type Lug Butterfly ValveWafer type lug butterfly valve are a type of quarter-turn valve that uses a circular disc to control the flow of fluids. The valve body features lugs (or ears) that allow it to be bolted directly to the pipeline flanges, eliminating the need for additio

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

Understanding Corrosion ResistanceWhat is Corrosion Resistance?Corrosion resistance refers to a material's ability to withstand chemical attack and degradation over time. In industrial settings, butterfly valves are often exposed to corrosive fluids, high temperatures, and fluctuating pressures, mak

Understanding Butterfly Valve SealsWhat are Soft Seals?Soft seals in butterfly valves are typically made from elastomeric materials such as EPDM (Ethylene Propylene Diene Monomer), NBR (Nitrile Butadiene Rubber), or PTFE (Polytetrafluoroethylene). These materials provide excellent sealing properties
