The options relate to valve stem sealing, trim materials, valve flow characteristics and Cv capacity values. They are described in (and may be selected from) this TI.Valve characteristicsSee typical flow characteristic curves chart oppositeThe standard characteristic for the 'C' series valve is equal percentage (E), however the following options are available:Equal percentage ELinear LFast opening FModified equal percentage MNote: Modified special characteristic trims are designed upon request.Valve stem sealingPTFE chevron (P)Design temperature 14°F to 482°F (-10°C to +250°C)Material PTFE chevronGraphite (H)Design temperature 14°F to 572°F (-10°C to +300°C) standard bonnet 14°F to 1004°F(-10°C to +540°C) extended bonnetBellows (B)Design temperature 14°F to 752°F (-10°C to +400°C)Material Carbon steel housing ASTM 216 WCBPressure rating ASME (ANSI) 150Plug and seat treatmentHardened (T)Design temperature 14°F to 797°F (-10°C to +425°C)Material Stainless steel AISI 431Leakage ASME (ANSI) Class IVPTFE soft seat (G)Design temperature 14°F to 356°F (-10°C to +180°C)Material PTFELeakage ASME (ANSI) Class VIHard face (W)Design temperature 14°F to 1004°F (-10°C to +540°C)Material Hard faced stellite AISI 316Leakage ASME (ANSI) Class IV or VSingle and multiple stage cageNoise reducing perforated cage (P)Design temperature 14°F to 1004°F (-10°C to +540°C)Material Stainless steel AISI 316 ENCAnti-cavitation cage (A)Design temperature 14°F to 662°F (-10°C to +350°C)Material Stainless steel AISI 316 ENCValve capacities see overleafValve size 1", 1½", 2", 2½", 3", 4", 5", 6" & 8" DN25, 40, 50, 65, 80, 100, 125, 150 & 200Valve series C = Cage trim E = Equal percentageValve L = Linearcharacteristic F = Fast opening M = Modified equal percentage 4 = Carbon steel 6 = Stainless steelBody material 8 = Alloy steel 2 = Butt weld (2" to 8")Connections 3 = Flanged 4 = Socket weld (1", 1½" and 2")Stem sealing P = PTFE chevron H = Graphiteoptions B = Bellows T = AISI 431 hardenedSeating G = PTFE soft seatoptions W = Hard faced stellite AISI 316 C = Standard cageType of trim P = Noise reducing perforated cage A = Anti-cavitation cage 1 = OneNumber of 2 = Twostages 3 = Three Other = To be specifiedTrim B = Balancedbalancing U = Unbalanced S = StandardBonnet type H = Extended for high temperature L = Extended for low temperature 0 = No Reduction 1 = 1 ReductionReduced trim 2 = 2 Reductions 3 = 3 ReductionsCv To be specifiedConnection To be specifiedtype2"CE43PTC1USCv 35ASME 300How to orderExample: 1 off 2" CE43PTC1US1 Cv 35 flanged to ASME 300.'C' series valve selection guide2" Cv 35 ASME 300Typical valve flow characteristics100500100500Flow %Valve opening %Fast opening LinearEqual percentage1C E 4 3 P T C 1 U S 1Valve capacities Flow coefficient Cv (US) depending on the various trim options - Kvs values are shown in brackets.
