They discharge the condensate near the saturation temperature.Field of Application.ProductName: TD42 thermodynamic steam trap.PressureRating: 1.6- 6.4 Mpa.Nominal Diameter: DN15-50mm.Body Material:Steel WCB,Stainless Steel.Standard flanges: DIN, ANSI, JIS.Standard Screwed:NPT,BSP.Main Technical Parameters and Indexes of Performance.Nominal pressurePN63Maximun design pressure(PMA)63bar gMaximun design temperature(TMA)400Minimun design temperature(TMI)-10Maximun upstream pressure for saturated steam service(PMO)42bar gMaximun operating temperature(TMO)400Minimun operating temperature(TMIO)0Minimun differential pressure( PMiX )0.25barMaximum cold hydraulic test pressure95bar gMaterial of Main Component.Name of componentMaterial of componentValve body, valve coverWCBOthersstainless steelMain ExternalDimensions.Product modelDN(mm)ConnectionDimensionLH1H2TD4215Internal thread80475420Internal thread90525925Internal thread95596232Internal thread10570.589.540Internal thread11070.589.550Internal thread12070.5104.5TD4215Socket welded80475420Socket welded90525925Socket welded95596232Socket welded10570.589.540Socket welded11070.589.550Socket welded12070.5104.5
