Orifice flow restrictor RILF series

This self-retained, threadless flow restrictor is the smallest available, allowing designers to save space and weight in metal housings. The orifice is 100% flow tested on distilled water to ensure that every part is within ± 5% of its nominal flow rate. Tighter tolerances are available as specials. To increase accuracy, the orifice is tested in the direction of use. An integral safety screen is incorporated for configurations with an orifice diameter of 0.5 mm (0.020 of an inch) or below. This restrictor is constructed entirely of stainless steel.Mounting Configuration: Insert - Into MetalDiameter: 2.54 mmMetered Flow Range: 1200 - 45,000 LohmsTest Fluid: Distilled WaterMaximum Working Pressure: 21 MPa (In Aluminum)General PerformanceCharacteristicSpecificationLohm Rate Tolerance± 5%Test FluidDistilled WaterMaximum Working Pressure21 MPa (In Aluminum)Designed for Installation IntoMetals, Such as Aluminum, Brass, Cast Iron, Stainless Steel, and SteelMaterialsComponentMaterialBody303 Stainless SteelPin, Unscreened416 Stainless SteelPin, Screened303 Stainless SteelScreen316 Stainless SteelScreen Body303 Stainless SteelCross Section Views: Unscreened Metered Flow Forward Configuration, Unscreened Metered Flow Reverse Configuration, Screened Metered Flow Forward Configuration, Screened Metered Flow Reverse ConfigurationDimensional Views: Unscreened Metered Flow Forward/Reverse, Screened Metered Flow Forward/Reverse (all dimensions in millimeters, overall length before installation)Installation Hole Details: Unscreened Forward/Reverse (Drawing Number: 1INST025565S), Screened Forward (Drawing Number: 1INST038333S), Screened Reverse (Drawing Number: 1INST038336S)Replacement Parts & Accessories: 2.5 mm Restrictor Installation Tool (Part Number: CCRT0029354S)Part Numbers & SpecificationsPart NumberFlow DirectionLohm RateScreen Micron RatingApproximate Weight (g)Installation Hole Drawing NumberRILF2551012SForward1200 LohmsN/A0.081INST025565SRILF2551015SForward1500 LohmsN/A0.081INST025565SRILF2551020SForward2000 LohmsN/A0.081INST025565SRILF2551025SForward2500 LohmsN/A0.081INST025565SRILF2551030SForward3000 LohmsN/A0.081INST025565SRILF2551040SForward4000 LohmsN/A0.081INST025565SRILF2551050SForward5000 LohmsN/A0.081INST025565SRILF2551060SForward6000 LohmsN/A0.081INST025565SRILF2553080SForward8000 Lohms40 microns0.11INST038333SRILF2553100SForward10,000 Lohms40 microns0.11INST038333SRILF2553120SForward12,000 Lohms40 microns0.11INST038333SRILF2553150SForward15,000 Lohms40 microns0.11INST038333SRILF2553200SForward20,000 Lohms40 microns0.11INST038333SRILF2553250SForward25,000 Lohms40 microns0.11INST038333SRILF2553300SForward30,000 Lohms40 microns0.11INST038333SRILF2553400SForward40,000 Lohms40 microns0.11INST038333SRILF2553450SForward45,000 Lohms40 microns0.11INST038333SRILR2551012SReverse1200 LohmsN/A0.081INST025565SRILR2551015SReverse1500 LohmsN/A0.081INST025565SRILR2551020SReverse2000 LohmsN/A0.081INST025565SRILR2551025SReverse2500 LohmsN/A0.081INST025565SRILR2551030SReverse3000 LohmsN/A0.081INST025565SRILR2551040SReverse4000 LohmsN/A0.081INST025565SRILR2551050SReverse5000 LohmsN/A0.081INST025565SRILR2551060SReverse6000 LohmsN/A0.081INST025565SRILR2553080SReverse8000 Lohms40 microns0.11INST038336SRILR2553100SReverse10,000 Lohms40 microns0.11INST038336SRILR2553120SReverse12,000 Lohms40 microns0.11INST038336SRILR2553150SReverse15,000 Lohms40 microns0.11INST038336SRILR2553200SReverse20,000 Lohms40 microns0.11INST038336SRILR2553250SReverse25,000 Lohms40 microns0.11INST038336SRILR2553300SReverse30,000 Lohms40 microns0.11INST038336SRILR2553400SReverse40,000 Lohms40 microns0.11INST038336SRILR2553450SReverse45,000 Lohms40 microns0.11INST038336SInstallation Procedures: Unscreened Forward/Reverse, Screened Forward/Reverse 2.5 mm Insert Orifice Installation Procedures availableInstallation & Manufacturing Tools: Installation Tool Drawing Number: CCRT0029354SCAD Envelopes: Unscreened Forward/Reverse, Screened Forward/Reverse 2.5 mm Insert Single-Orifice Restrictor for Liquids Models availableKey Product Facts: Mounting Configuration: Insert - Into Metal; Diameter: 2.54 mm; Metered Flow Range: 1200 - 45,000 Lohms; Test Fluid: Distilled Water; Maximum Working Pressure: 21 MPa (In Aluminum)
