Leakage(Optional)Valve Body, Valve Cover: Brass Connection: Screwed DIN2999 BS21  Installation1. balance valve maybe installed in either the return line or the supply line at only one location per loop. It is recommended to install the balance valve in the return water line with low water temperature.2.The balance valve on the main pipe should be installed at the outlet direction of the water pump.3.Balance valve can be installed horizontally or vertically.4. The direction of medium flow should be consistent with the direction marked on the valve body.5.The opening indicator number on the handle should be in the direction visible to the debugging personnel to facilitate debugging. There should be no obstacles in front of the measuring joint on the valve body in case the debugging instrument cannot be connected during debugging. when installed in the ceiling, the handle should be facing down.Key featuresHigh accuracy for all settingsEnsure accurate balancing and flow readingHand wheel Equipped with a digital read-out, the hand wheel ensures accurate and straightforward balancing positive shut off function for easy maintenanceSelf sealing measuring points  For simple accurate balancing, and can add a change drain and connector for G1/4 to PDCV tube.metalHPB59-1 resistant alloy that guarantee a longer valv e life time and lowers the risk of leakage Technical descriptionApplication : Heating and colling systemsTap water systems Functions BalancingPre-settingMeasuringShut-offDraining( Depending on valve type)Dimensions DN15-50Presure Class  PN25 Temperature Max working temperature:120ºCintermittent150ºC for higher temperatures ( max.150ºC) min, working temperature -20ºCMedia Water or neutral fluids, water-glycol mixtures (0-57%)KVS DN15DN20DN25DN32DN40DN50KVS m³/h2.985.136.969.75 /nt12.38/nt22.5/ ntSetting Valve closed                        set at 2.3                      full opennt: the design KVS/not under test, ItemPartsMaterialSurface01BodyBrassNickel02CartridgeBrassOriginal brass03Female BushingBrassOriginal brass04NutBrassOriginal brass05PlugeBrassOriginal brass06ConnectorPlasticRED, BLUE07CoverPlasticGray08Handle wheelPlasticBlack Red09&10GasketEPDMBlack     SizeD mmL mmH mmWeight-g(±2%)1/2G 1/290875403/4G 3/497876301G 111090.58301 1/4G 1 1/41249711001 1/2G 1 1/213010714602G 2154110.52110WRANING1. The opening of the balance valve should not be arbitrarily changed. After debugging of the balance valve installed in the pipe network system, in order to maintain the balance state of the system, the opening of the balance valve should not be arbitrarily changed during the normal operation of the system, especially the opening locking device.2. Pay attention to the balance between the new system and the old systemWhen a new system installed with a balance valve is connected to the original system, attention should be paid to the balance of water flow distribution between the new system and the original system so as to prevent the new system (or modified system) installed with a balance valve from reaching the proper water flow. A balance valve should be installed at the entrance of the original system.   Quality Control  Hot forge Our brass valve is produced by forging, through forging the valve product strength is greater, no porosity, can effectively prevent the leakage of the valve body.CNC MachiningOur products are processed by precision CNC machine tools, with high machining accuracy up to 0.1 micron. We have machining centers to meet customers' requirements for products with high coaxiality Machining Inspection  In our machining process, each size needs to be strictly tested. Workers will conduct a self-inspection of their products every 2 hours, and QC will conduct a workshop inspection every 2 hours to ensure that the size of products fully meets the requirements of the drawingsAssembly RoomOur assembly shop USES the assembly line, the result of teamwork can guarantee the output of a large quantity of products.100% of the products on the production line need to pass the leak test. We use the pressure of 6-8bar to test each product. Only after passing the test can the products be packed into cartons.FAQ 1. Can I have a sample order for valve?A: Yes, we welcome sample order to test and check quality. Mixed samples are acceptable2
