Orifice flow restrictor RIGF series

This self-retained, threadless restrictor is the smallest available, allowing designers to save space and weight in metal housings. The orifice is 100% flow tested on nitrogen to ensure that every part is within ± 5% of its nominal flow rate. Tighter tolerances are available as custom configurations. 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: Clean & Dry NitrogenMaximum Working Pressure: 21 MPa (In Aluminum)General PerformanceCharacteristicSpecificationLohm Rate Tolerance± 5%Test FluidClean and Dry NitrogenMaximum 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 SteelPart Numbers & SpecificationsPart NumberFlow DirectionLohm RateScreen Micron RatingApproximate Weight (g)Installation Hole Drawing NumberRIGF2551012SForward1200 LohmsN/A0.081INST025565SRIGF2551015SForward1500 LohmsN/A0.081INST025565SRIGF2551020SForward2000 LohmsN/A0.081INST025565SRIGF2551025SForward2500 LohmsN/A0.081INST025565SRIGF2551030SForward3000 LohmsN/A0.081INST025565SRIGF2551040SForward4000 LohmsN/A0.081INST025565SRIGF2551050SForward5000 LohmsN/A0.081INST025565SRIGF2551060SForward6000 LohmsN/A0.081INST025565SRIGF2553080SForward8000 Lohms40 microns0.11INST038333SRIGF2553100SForward10,000 Lohms40 microns0.11INST038333SRIGF2553120SForward12,000 Lohms40 microns0.11INST038333SRIGF2553150SForward15,000 Lohms40 microns0.11INST038333SRIGF2553200SForward20,000 Lohms40 microns0.11INST038333SRIGF2553250SForward25,000 Lohms40 microns0.11INST038333SRIGF2553300SForward30,000 Lohms40 microns0.11INST038333SRIGF2553400SForward40,000 Lohms40 microns0.11INST038333SRIGF2553450SForward45,000 Lohms40 microns0.11INST038333SRIGR2551012SReverse1200 LohmsN/A0.081INST025565SRIGR2551015SReverse1500 LohmsN/A0.081INST025565SRIGR2551020SReverse2000 LohmsN/A0.081INST025565SRIGR2551025SReverse2500 LohmsN/A0.081INST025565SRIGR2551030SReverse3000 LohmsN/A0.081INST025565SRIGR2551040SReverse4000 LohmsN/A0.081INST025565SRIGR2551050SReverse5000 LohmsN/A0.081INST025565SRIGR2551060SReverse6000 LohmsN/A0.081INST025565SRIGR2553080SReverse8000 Lohms40 microns0.11INST038336SRIGR2553100SReverse10,000 Lohms40 microns0.11INST038336SRIGR2553120SReverse12,000 Lohms40 microns0.11INST038336SRIGR2553150SReverse15,000 Lohms40 microns0.11INST038336SRIGR2553200SReverse20,000 Lohms40 microns0.11INST038336SRIGR2553250SReverse25,000 Lohms40 microns0.11INST038336SRIGR2553300SReverse30,000 Lohms40 microns0.11INST038336SRIGR2553400SReverse40,000 Lohms40 microns0.11INST038336SRIGR2553450SReverse45,000 Lohms40 microns0.11INST038336SInstallation Tool: CCRT0029354S (2.5 mm Restrictor Installation Tool)CAD Models: Unscreened Forward, Unscreened Reverse, Screened Forward, Screened Reverse 2.5 mm Insert Single-Orifice Restrictor for Gases Models (available upon request)Handbook Reference: Industrial MicroHydraulics Handbook of Automotive and Industrial Solutions Page A25-A26, A31-A34Technical Specifications / Features:Self-retained, threadless designSmallest available restrictor for metal housings100% flow tested on nitrogen±5% nominal flow rate toleranceCustom tighter tolerances availableTested in direction of useIntegral safety screen for ≤0.5 mm orificeAll stainless steel constructionMounting: Insert into metalDiameter: 2.54 mmMetered Flow Range: 1200 - 45,000 LohmsTest Fluid: Clean & Dry NitrogenMax Working Pressure: 21 MPa (in Aluminum)
