The steps shown in each example should not be taken as the only method available to create models. In addition, the intent of the examples is to present ways to create adequate models of specific piping components for analytic purposes.

1. AutoPIPE does apply thermal expansion coefficients to VALVE components. The corresponding Temperature load case, (ex. T1, ..Tn) and expansion parameters on the Press/Temp/PipeID input grids are used to determine how much expansion will occur.
Comments, Questions, and Answers:
Item #0: Specific valve was missing from catalog, how to model valve?
Item #1: Model a 3-way valve
Item #2: Why does valve's Pressure Rating drop-down list only NS (Non-Standard)?
Item #3: Model a complex valve such as a Bell & Gossett Triple Duty Valve
Item #4: Model an Angle valve (90 deg valve)
Item #5: Model a pressure relief valve
Item #6: Why is wrong weight used when inserting a valve?
When inserting a valve with flanged end connections on both side, the wrong weight is automatically applied to the flanges. example: add a GateF Class 300 valve and tick the insert flanges option the flanges by default are the same weight as the valve.
This is a known issue and has been logged under CAE-TR-10614 Using insert flange on both ends copies the weight of valve to flange and was fixed in AutoPIPE V8i 09.06.00.07 and higher.
Item #7: Model a Fire hose valve
Item #8: Model Valve + actuator based on catalog info with combined values
Item #9: Model a Butterfly valve
Item #10: Model a Large double offset valve
Issue #11: Model Valve actuator and support
Issue #12: On a valve dialog, what is the Surface Area factor and how is is calculated?
Issue #13: Model a valve that is submerged in water?
Issue #14: What is the stiffness value of a valve?
Item #15: What to do when Flange / Valve Rating is not listed in drop down listing?
Item #16: Why Valve dialog drop down listings do not contain specific information?
Item #17: Model a Reducing valve
