Compact Ductile Iron Body and Concentric Design Wafer Butterfly Valve

Compact Ductile Iron Body and Concentric Design Wafer Butterfly ValveProduct DescriptionButterfly valve is opened and closed by disc type Reciprocating gyrati Open close and adjust at about 90 degrees A valve for regulating fluid passages. Butterfly valves are not only simple in structure, small in volume, light in weight, low in material consumption, small in installation size, small in driving moment, simple in operation and fast in operation, but also have good flow regulation function and sealing characteristics.They are one of the fastest growing valve varieties in recent decades. Especially in developed countries such as  America, Japan, Germany, France and Italy, butterfly valves are widely used. The varieties and quantities of butterfly valves are still expanding, and they are developing toward high temperature, high pressure, large caliber, high sealing, long life, excellent regulation characteristics and multi-function of valves.Their reliability and other performance indexes are all equal. Up to a higher level, and has partially replaced globe valves, gate valves and ball valves. With the advancement of butterfly valve technology, butterfly valve will become the dominant valve form in a predictable short time, especially in the field of large and medium caliber, medium and low pressure. In order to meet the requirements of industrial applications such as high and low temperature, strong erosion and long service life, metal-sealed butterfly valves have been greatly developed in recent decades.  With the application of high temperature resistance, low temperature resistance, strong corrosion resistance, strong erosion resistance and high strength alloy materials in butterfly valves, metal-sealed butterfly valves have been widely used in high and low temperature, strong erosion resistance, long life and other industrial fields, so that the technology of butterfly valves has reached a new level.Advantages:Butterfly valves are easy and fast to open.Butterfly valves are relatively inexpensive to build.Butterfly valves have less space requirements.Butterfly Valves are generally associated with reduced maintenance.Specification   Size:11/2 "- 24Connection mode:FlangePressure ranking:Class125/Class150Working pressure:1.6MpaFlange standard:ANSI B16.1    Seat materialPressure leveltest pressure Operating temperature,(-10-80ºC) and allowable pressure MPaOperatingtemperature,(-80-120ºC) allowable pressure MPaOperating temperature,(150ºC) allowable pressure MPaApplicable mediumNBR(-10-80ºC)PN101.51.0--Water, sewage, seawater, oil, gasPN162.41.6--PN253.82.5--EPDM(-10-120ºC)PN101.51.01.0-Water, sewage, seawater, oil, gasPN162.41.61.6-PN253.82.52.5-VITON(-10-150ºC)PN101.51.01.00.30Water, sewage, seawater, oil, gasPN162.41.61.60.45PN253.82.52.50.60PTFE(-10-150ºC)PN101.51.01.00.30Water, sewage, seawater, oil, gasPN162.41.61.60.45PN253.82.52.50.60  NPS221/23456810121416182024283032364048DN50658010012515020025030035040045050060070075080090010001200PN10L(mm) 43464652565660687878102 114127154165190190203216254Torque valueN/M16202643881012473383948841105152619683370------PN16L(mm) 43464652565660687878102114127154165190190203216254Torque valueN/M202334521011203933904689271755195027735070------PN25L(mm) 43464652565660687878102114127154165190190203216254Torque valueN/M2227396011713833744953810662019224331895831------                                 Packaging & Shipping    Equipment   Company ProfileShanghai Flow Valve &Fitting Co, Ltd. was founded in 1998, mainly in foreign trade export business, has invested in two professional manufacturing factories in Shanghai Jiading Waigang Industrial Zoneand Tianjin Wuqing Jingbin Industrial Park.These two subordinate factories are responsible for the professional production of ANSl, DINBS, GB and other standards of ball valve, butterfly valve, gate valve, stop valve, balance valve, filter, plug valve, control valve and other series of products.Nearly 80% of the company's products are exported to Europe,America, the Middle East, Southeast Asia and other parts of the world and we also conduct technical cooperation and OEM production with many European and American companies.Shanghai Flow Valve & Fitting Co., Ltd. began to actively participate in major domestic engineering projects in 2003.lt has established five sales centers in Shanghai, Beijing, Guangzhou, Xi'an and Chongqing, and its business covers northeast China, North China, northwest China,Southwest China, Central China, South China and other regions.The sales network and after-sales network basically cover most regions of mainland China. Certifications   Exhibition   FAQQ1: Can I have a sample order for valve?A1:Yes, we welcome sample order to test and check quality.
