Concentric Wafer Type Spline Full Stem Butterfly Valve for Marine

Concentric Wafer Type Spline Full Stem Butterfly Valve for Marine   Industrial UseThe butterfly valves are widely used in piping of chemical, food, medicine, paper making, water and electricity, shipbuilding, water supply and drainage, metallurgy and energy systems, and is available for regulating and closure devices in a variety of corrosive, non - corrosive gas, liquid, semi-liquid and solid powder pipelines and containers.     Strengths: 1. Midline butterfly valve is compact in structure and light in weight, and easy for assemly and disassembly, and maintenance. 2. The operaturing torque of it is small. 3. It is small in flowing resistance and good in erengy-saving effect, with discharge characteristic approximating inclined straight line. 4. It is featured by reliable sealing, zero leakage with ten thousands of opening and clising times, 5. The valve can be made of various materials, adapted to all kinds of media. 6. They are used in the pipelines and vessels for conveying various corrosive and non-corrosive fluid media in thr engineering systens of water supply generating, petroleum, gas, chemicals, smelting, food, medicine, paper-making, shipping and environmental protection and also for regulating and cutting off the flowing of media.   Performance Specification Nominal Diameter (DN)25(1")~600(24")25(1")~600(24")DN (inch)Nominal Pressure (PN)1016BAR  Test PressureBody1524Sealing1117.6Working temperatureºC-15ºC~+150ºCApplicable MediumsFresh water, sewage, sea water, air, steam, food, drug, various oil, acid, alkali, salt, etc.Note: Applicable temperature and mediums are depending on the materials of different valve seats, bodies, stems and discs, see table 1 and table 2: Regular Material of the Main Parts (Table 1)BodyDiscStemNameCodeNameCodeNameCodeCast IronGG25Electric-platedDIGGG40+NiStainless Steel416/316Ductile Iron(DI)GGG40AL-BronzeC954/C958 431/17-4AL-BronzeC954/C958 Stainless SteelCF8/CF8M  Stainless SteelCF8/CF8MCoating DIGGG40+Nylon  Carbon SteelWCB      Materials listItemPart name                      Materials1Clamping ring     Zine plated steel / Stainless steel2O-Ring     EPDM / NBR / Neoprene / Viton3Bushing     PTFE / Lubricated bronze4Stem     Zine plated steel / Stainless steel5Body     Cast iron / Ductile iron / Stainless steel6Disc     Ductile iron(nickel plated) / Stainless steel / AL-Bronze7Seat     EPDM / NBR / Neoprene / VitonDear Prospective Customer, AFCON adheres to the following Core Values:O Personal and Professional Working RelationshipsO Complete Trust and Respect for each person on Our TeamO "Quality IS our Business" With over 10 years of growth development and experience with our successful product research, manufacturing expertise and sales performance we have proven that "Quality IS our Business".  Quality sets the guidelines and targets that we need to meet our Customers demands therefore ensuring we continually endeavor to strive for improvement with our  Research and Development, products and standards so they always meet with and satisfy the ever increasing needs and demands of our customers.  We also have a specific focus to develop products that enhance 'Safety' and the workplace.
