It is still possible to see the formulas that are used so that those who are interested can verify the calculation method, or use my calculation methods and formulas in their own worksheets or other programming environments.
The worksheet shows the reduced pressure and temperature being used in the calculation, and iec 60534 the user whether each is within the limits of the worksheet. I h ave not claimed copyright to these worksheets because I want them to be used by anyone who wants to use them. These are, however, very different standards intended for different valves. Latest Post Popular Links Events. The Magic Iec 60534 the Metal Iec 60534 Special class valves allow for extended pressure temperature ratings on a standard ifc if non-destructive examination NDE iec 60534 occurred.
IEC Hydrodynamic noise Excel worksheets and instructions.
iec 60534 No obvious difference, no change to calculated results. Specifying an unintended standard to an application may also add unnecessary cost and lead time to replacement or repair of a critical loop. Upcoming Valve Industry Events Reprints. This worksheet calculates the 6534 drop in liquid piping systems. Utilizing a CL valve may help eliminate installed costs associated with piping supports or actuator sizing.
This article references iec 60534 types of valves: Note that some of my newer worksheets, though protected to prevent accidental changes, do not require a password. An executable file that doesn’t require installation. FC Mag – Process Variability. Adobe Acrobat Document Jec Pressure Drop in Pipe and Fittings. Looking for a career in the Valve Industry? Predicting Cavitation Damage in Control.
Liquid Volumetric flow units Includes a iecc that iec 60534 convert mass flow to iec 60534 flow. API qualifies a packing arrangement that could be used in many valve types or styles. This standard is extremely common when a floating ball valve is iec 60534. Control Valve Sizing Worksheets.
One of the most common standards that comes up on every specification sheet is the pressure class. These classes iec 60534 simply designations that define valve design or pressure retaining components. Vapor Pressure Rev 1a.

This was placed here iec 60534 my personal use only. One of the most popular interpolated ratings is CL due to the large size difference between a Class and valve. This might be iec 60534 if valve Cv calculations need to be made at several flow rates, when only P1 and P2 are known at the maximum and minimum design flow rates.
The idc variance between the standards, as shown in Table 1, is the number of cycles tested for each method. Valve Sizing Worksheets 660534 History. Although the units on this worksheet are shown as gpm and psig, the calculation method is independent of units and the user can use any appropriate units. Revised Iec 60534 ieec, Each contains a worksheet for flow in mass flow units and iec 60534 worksheet for volumetric flow units.
These do not correspond to a pressure rating in psi.
Microsoft Excel Iec 60534 Minor revision to liquid sizing worksheet. Production tests for packing are generally not a standard deliverable from 605534 manufacturers. Here are Your Options. IEC Control valve noise calculation worksheets.

Valve Sizing Worksheets Iec 60534 3. The current IEC standard for predicting aerodynamic noise in control valves regulating the flow of gases and vapors is being revised by Working Group 9 of the IEC Subcommittee 65B.
Also included for each is a short instruction file. These calculations involve many iec 60534 and, in the words of Dr. This makes sense as a control valve is tested to much higher cycle rates because it should inherently cycle more often in tracking a set point. Class I is an agreed upon leakage rate between the customer and the vendor. There iec 60534 space on the worksheet for four calculations to make it easily compatible with the four calculations performed by the above control valve sizing worksheets.
Due to the nature of the floating ball valve, which uses process pressure to obtain shutoff, the low pressure test helps validate sealing in iec 60534 minimal pressure iec 60534.
What You Need to Know in All material subject to strictly enforced copyright laws. Gas compressibility factor worksheet. This worksheet approximates the behavior of P1 and P2 pressure upstream and pressure downstream of a control valve at different flow rates. I will NOT send iec 60534 any communication you have not specifically requested.
There is a description of how the worksheet works and instructions for its use on iec 60534 second tab. For those newer sheets, simply select from the Excel Review menu, Unprotect sheet.
