Bronze/Cast Iron/Carbon Steel Body BS4504/ANSI B16.1/DIN999/BS21 Standard Size 2'--24' PN16/25/40 Class 125/150 HandWheel Operated Flange End Balance ValveProduct DescriptionBalance valves are utilized in central heating and cooling systems that rely on flow of water through the system.They use the latest flow technology to ensure that the design flow rate is achieved at all times irrespective of any pressure changes within the system.A cooling or heating water distribution system is in balance when the flow in the whole system (through the component terminal lines, distributing lines and main distributing lines) corresponds to the flow rates that were specified for the design of the system.If the correct balancing of the system is not established, this will result in unequal distribution of the flow, so that there will be a surplus effect in some of the terminals, whereas the effect will be inadequate in others.As a consequence, the required heating or cooling will not be ensured in all parts of the installation.Practically, it is not possible to achieve a completely balanced system by manipulation of the piping or alteration of the pipe dimensions only.Only a correct set of balancing valves can ensure the correct distribution of the flow in the system.  SpecificationNO.NameMaterial  Chinese Spec.ASTM Spec.1BodyHT250QT450-10ASTM 126-ClassBA536 65-45-122DiscDI + EPDMA536 65-45-12 + EPDM3CoverHT250QT450-10ASTM 126-ClassBA536 65-45-124Stem1Cr13ASTM A270 410Nominal Diameter: DN350-DN500/14''-20''Nominal Pressure: Class125/PN16Design Standard:BS7350Flanged End Standard: ANSI B16.1/EN1092-2Working Temperature: -20ºC- 120ºCNPS14161820DN350400450500L7728589381050Kv3172352641104791Cv3702411547965591Weight(kg)3805507801020 Advantages1,The balancing valve has good flow characteristics, can control and regulate the flow rate precisely.   By set the position of the disc and control the flow rate, it can solve the hydraulic balancing problem in the heating and air condition system      effectively. (Flow rate regulating has memory function.)2,The balancing valve has close off function as well. Close the disc can stop the flow of the medium.3,Suitable medium is Water, Gas and Oil.Packaging & Shipping   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.  Certifications Exhibition FAQQ1: Can I have a sample order for valve?A1:Yes, we welcome sample order to test and check quality.
