2 Turns off its Reducing ValveTypical ApplicationsTypical applications include pressure reducing valve stationusing MODEL 90-01 and MODEL 90-01in parallel to handle widerange of flow rates. Larger MODEL 90-01 valve meetsrequirements of peak loads and smaller MODEL 90-01 handleslow flows. A downstream pressure relief valve is alsorecommended for this type of PressureIsolation ValveGaugeConstantDownstreamPressureCLA- VAL 90-01 Pressure Reducing ValveCLA-VAL 90-01 Pressure Reducing ValveX43H StrainerX43H StrainerGaugeIsolation Valve Sensitive and Accurate Pressure Control Easy Adjustment and Maintenance Optional Check Feature Fully Supported Frictionless Diaphragm Meets National Lead Reduction MandateThe Cla-Val MODEL 90-01 Pressure Reducing Valve automaticallyreduces a higher inlet pressure to a steady lower downstreampressure.

3 Regardless of changing flow rate and/or varying inletpressure. This valve is an accurate, pilot-operated regulator capable ofholding downstream pressure to a pre-determined limit. Whendownstream pressure exceeds the pressure setting of the control pilot,the main valve and pilot valve close a check feature is added, and a pressure reversal occurs, thedownstream pressure is admitted into the main valve cover chamber,closing the valve to prevent return space savings, see Cla-Val MODEL 90-48 or 90-99 with integral LowFlow Bypass Pressure MODEL 90-01 KOPressure Reducing Valve with Anti-Cavitation Trim provides for optimum downstream pressurecontrol while reducing noise and eliminating damage associatedwith cavitation.

4 See Cavitation Guide to determine if the valve is acandidate for the KO Anti-Cavitation Trim. A downstreampressure relief valve is recommended for this type of sizes 18 through 36-inches, use 90-66 E-Sheet MODEL 90-01 (Uses 100-01 Hytrol Main Valve) MODEL 90-01 Dimensions(In Inches)ComponentStandard Material CombinationsBody & CoverDuctile IronCast SteelBronzeAvailable Sizes1" - 36"25 - 900mm1" - 16"25 - 400mm1" - 16"25 - 400mmDisc Retainer &Diaphragm WasherCast IronCast SteelBronzeTrim: Disc Guide, Seat & Cover BearingBronze is StandardStainless Steel is OptionalDiscBuna-N RubberDiaphragmNylon Reinforced Buna-N RubberStem, Nut & SpringStainless SteelFor material options not listed, consult manufactures valves in more than 50 different (MAX)KJHI nletOutletB(Diameter)YZGGGGGGDI nletDDDDDFFFX100-01 Threaded &FlangedAEC(MAX)KJHI nletOutletAAAAAB(Diameter)
