At the time of partial load, when the controlflow of the regulator is reduced, the pressure limit is still used to achievedynamic balance. Maximum flow limitedThe flow limiting function is achieved by combining the differentialpressure control valve HTV03023 with a configurable end valve. The flowlimiting function prevents end underflow and makes the pump work moreefficiently.Reduced noiseLimiting the pressure difference at both ends of the regulatingvalve can avoid excessive pressure drop at both ends of the regulating valveunder partial load, and make the noise of the regulating valve under partialload less.Do not need to balancedebuggingFlow limits are achieved by setting eachhydraulic loop as an independent loop that does not interact with each other sothat it only needs to be set once. No special balancing measures are needed.Can greatly save debugging costs. technical specificationITEMDN15-25MAXMIUM PRESSUREBRA16(PN16)TEST PRESSUREBAR25VALVE PRESSURE DIFFERENTKpa10-150Even in the case of partial load, the maximum pressure difference at both ends of the valve is not allowed to exceed 150KpaTEMPEREATURE oC-20---120The material that touches the waterValve bodyBrass CW617NStem plugBrass CW602N (DZR)MembraneEPDMSpring SUS 304DesignThe HTV03023 is designed to maintain aconstant set pressure difference. The pressure of the return pipe acts on thelower volume of the control diaphragm, while the pressure difference of thewater supply acts on the upper side of the diaphragm through the pulse tube.The set pressure difference is maintained by the internal structure and theadjustment springFactorysetting 10KpaType selectionWe recommend using Figure6 toselect the diameter of the differential pressure balancing valve. The maximumflow rate is calculated according to the valve pressure difference of 10KPa,which ensures the efficient use of the pump and saves energy.For example:Known: pipe flow 200L/h, pipe diameter DN15Result: At the vertical axis flow 200L/h, make a horizontal line to the right,intersect with the bar chart, select DN15 valve.The relationship between valve size andpipe sizeThe Kv value of each specification isdetermined based on a flow rate range of up to 0.8m/s at 10KPa valvedifferential pressure. As long as the flow rate of water in the pipe is between0.3 and 0.8 m/s, the valve size should be equal to the pipe size.other more application details please sent e-mail to take the detils, and HTV03602 is the patner valve with HTV03023, in FIGURE5 you will find the balance valve KVS and choose the selection click the number or picture to go to check the balance valve
