34 Description Stainless steel wire screens are mounted within the precision orifice assembly to protect the orifice from contamination that could be introduced during handling or installation. The fine screens are not intended to replace normal filtration equipment, but rather to augment the protection of small orifices. Applications The integral screen/orifice assembly provides a compact arrangement. All types on this page The screen is located upstream of the orifice and protects against particles carried by the pressurized fluid. For protection against contamination in reverse flow situations add an external screen downstream of the orifice. General Specifications Maximum Operating Pressure – See page 35. Maximum Operating Pressure Differential (MOPD) – 100 psi. Flow – See flow charts on pages 20 and 21. The screen will cause a decrease of 1 to 2% in flow chart value. Orifice Diameter Accuracy – ±.0003" C v Range – .00035 to .028 See pages 20 and 21. Fluid Media – Air, Water, Gases and Liquids compatible with materials of construction. Dimensions – See drawings on page 35. Screen Material – 304 SS Screened Metal Orifices INTEGRAL WIRE SCREENS Orifice Size Size Dia. Number Number In.
