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,

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

Understanding Butterfly Valve LifespanCommon Challenges• Corrosion: Exposure to corrosive media can degrade valve materials, leading to leaks and reduced performance.• Wear and Tear: Frequent operation and harsh operating conditions can cause mechanical wear, affecting the valve's sealing capabiliti

Understanding EN 593 StandardScope and ApplicabilityEN 593 is a European standard that specifies the minimum general requirements for metallic butterfly valves used in various applications, including water supply and wastewater treatment. The standard covers a wide range of sizes and pressure rating

In the production process of J-VALVES butterfly valves, the casting process plays a crucial role. Sand casting and investment casting are two commonly used methods, each with its own characteristics. Understanding their cost-benefit situations is of great importance for enterprises to choose the appropriate process and control production inputs and outputs. Now, let's conduct a comparative analysis of the cost-benefit of these two casting processes.

​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.
