24DescriptionStainless 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 assembly providesa compact arrangement.All types on this pageThe screen is located upstream of theorifice and protects against particlescarried by the pressureized fluid.For protection against contamination inreverse flow situations add an externalscreen downstream of the orifice.General SpecificationsMaximum Operating Pressure –See page 25.Maximum Differential Pressure AcrossScreen – 100 psi.Flow – See flow charts on pages 16 and 17.The screen will cause a decrease of 1 to 2%in flow chart value.Orifice Diameter Accuracy – ±.0003"C v Range – .00035 to .028See pages 16 and 17.Fluid Media – Air, Water, Gases andLiquids compatible with materials ofconstruction.Dimensions – See drawings on page 25.Screen Material – 304 SSScreened Metal OrificesINTEGRAL WIRE SCREENSOrifice SizeSize Dia.
