In the food processing and other industries, the hygienic design of food-grade lug butterfly valves is of vital importance as it relates to the safety and quality of food. The 3A certification and FDA material compliance are two key aspects for measuring whether they meet the standards. The following is an in-depth interpretation and comparison of their relevant requirements for you.<br />  

relevant mandatory certifications can better ensure product quality and usage safety. The UL (Underwriters Laboratories), FM (Factory Mutual), and CE (Conformité Européene) certification standards are widely used in the fire protection field and each has its own characteristics. The following is a comprehensive analysis of their certification requirements for LUG BUTTERFLY VALVES, and the differences will be presented more clearly in the form of a table comparison.

​In the application field of J-VALVES FULL LINED FLUORINE BUTTERFLY VALVES, the selection of sealing materials is of crucial importance, as it directly affects multiple aspects such as the sealing performance, service life, and applicable working conditions of the BUTTERFLY VALVES. PTFE (Polytetrafluoroethylene) seals and EPDM (Ethylene Propylene Diene Monomer) gaskets are two commonly used materials. In order to gain an in-depth understanding of the differences in their performance, we conducted a specialized comparison experiment.

I. Common Material Types and Performance Parameters of Bronze Butterfly Valves<br /> <br /> <br /> The common material types of bronze butterfly valves mainly include nickel-aluminum bronze, aluminum bronze, and cast iron, etc. Among them, nickel-aluminum bronze is a relatively common choice due to its excellent corrosion resistance, especially suitable for seawater environments. Aluminum bronze is also widely used in the industrial field because of its good corrosion resistance and wear resistance.<br /> <br /> <br /> In terms of performance parameters, bronze butterfly valves usually have the following characteristics:

In many high-temperature and high-pressure scenarios in industrial production, the choice of butterfly valves is quite an important matter. Today, let's make a good comparison between bronze butterfly valves and stainless steel butterfly valves to see what the differences are in terms of material performance and standard adaptability.
