26DescriptionStainless steel wire screens are mountedwithin the precision orifice assembly toprotect the orifice from contaminationthat could be introduced during handlingor installation. The fine screensare not intended to replace normal filtrationequipment, but rather to augmentthe protection of small orifices.ApplicationsThe integral screen/orifice assemblyprovides a compact arrangement.Type BTFS and BWFS – The screen islocated upstream of the orifice andprotects against particles carried by thepressurized fluid.For protection against contamination inreverse flow situations add an externalscreen downstream of the orifice.Type JSS – The dual screen protects theorifice from particles that could enter ineither direction.General SpecificationsMaximum Operating Pressure –100 psigMaximum Differential PressureAcross Screen – 100 psiFlow – See flow charts on page 18.The screen will cause a decrease of1 to 2% in flow chart value.Orifice Diameter Accuracy – ±.0003"C v Range – .000030 to .013See page 18.Fluid Media – Air, Water, Gases andLiquids compatible with materials ofconstruction.Dimensions – See drawings on page 27.Screen Material – 304 SSScreen Filter RatingsOrifice MicronSize No. Rating3 - 26 1528 - 40 2544 - 64 100Screened Sapphire OrificesINTEGRAL WIRE SCREENSOrifice SizeSize Dia.
