Ball Valve Markings & Tags Ball Valve Markings & Tags Presentation Transcript

  • Identifying Valves forInterchanges & RetrofitsPart ICasting Markings & Tags on Ball Valves
  • 2Overview Valve markings Tagging information Marking & tagging deciphered Other needed information Metric equivalents Pressure & Temperature
  • 3Sound Familiar?“Help, I need one of these…”So how do you find out what “this” is?
  • Typical Valve Markingsvalve sizebodymaterialvalve sizepressure classcasting numbermountinginformation
  • Markings Deciphered: Valve Size DN32 is simply “diametre nominel” and is the metric equivalent of nominal pipe sizewith the next number the size of the pipe in millimeters. The number next to that is the pipe size in inches.valve sizevalve size
  • Markings Deciphered: Mounting Information F04/F05 refers to the ISO mounting* patterns that are used to mount actuators.mountinginformation* Future series
  • Markings Deciphered: Body Material 1.4408-CF8M refers to valve body material. CF8M is a cast 316 stainless steel.bodymaterial
  • Markings Deciphered: Pressure Class PN is “pressure nominal” and is the pressure class of the valve in bars (1 bar=14.5038psi). 1000 is adding the psi equivalent to make it easy to look at in the field.pressure class
  • Markings Deciphered: Pressure Class R8F98 is a casting number from the foundry. It is used to track materials and batches.These are needed to supply Material Test Reports (MTRs). Depending on the body stylethere can be more than one of these marks.casting number
  • Other Markings You Might See WCB - a grade of cast carbon steelcommonly used for valves CW617N - the European designation forbrass valves with high zinc content NACE – indicates that the valve is rated forsour gas service ANSI - flange class of valves* 125/150 250/300 600 up to 2500 FNPT or MNPT - male or female threadedend connections WOG – stands for water, oil, gas and is anolder way of representing a valve’spressure rating. SWP – Steam working pressure* Future series

  • Valve Tagging Deciphered Body refers to the valve casting portion ofthe assembly. Seat is the material the valve ball is goingto seal against. Seats are offered in a widerange of materials and can even be metalfor severe services. A valve’s trim includes the internal partsof the valve such as the ball and stem. CWP stands for Cold Working Pressure andindicates the valve pressure rating from-20 to 100F. Higher temperatures canseverely degrade a valve or pipe’s pressurerating. Check out thepressure/temperature chart on slide 11.12
  • Putting it Together in Part IAble to Identify Materials of construction Valve size Pressure rating Valve mfg. & model #Up Next End connections Automation Butterfly valves Mounting hardwareTip:When possible, try and get information on actual working conditions of the valve.It helps to get the whole picture and allows for a cost-effective and accuratequotation.
  • Metric Equivalents 1 bar = 14.058 psi 25.4 mm = 1” Deg F = (C+17.78) X1.8 1 kilopascal(kPa) = .145 psiNPS DN1/4" 8 mm3/8" 10 mm1/2" 15 mm3/4" 20 mm1" 25 mm1-1/4" 32 mm1-1/2" 40 mm2" 50 mm2-1/2" 65 mm3" 80 mm4" 100 mm5" 125 mm6" 150 mmPN Flange Class20 15050 30068 400100 600150 900250 1500420 2500

The values in this table apply to Material Group 1.1 (i.e. certain carbon steel grades). For other Material Groups the Pressure-Temperature Ratings aredifferent. Most carbon steels are only acceptable for temperatures below 800 FPressure & Temperature
