VRGSize ver 5.2 Station Design and PRCV Control Valve Sizing Program

SEE BELOW FOR NOTES ON VERSION UPDATES

 

VRGSize is a convenient spreadsheet type application that provides useful tools for sizing and selection of VRG Controls PRCV Series control valves.  The program also allows the user to develop cursory design of complete natural gas regulator stations.  The program is a protected GUI macro-driven spreadsheet that runs within a MS Excel shell and requires the user to have a licensed version of MS Excel installed on their computer.

 

Features:

  • Size and select VRG Controls PRCV Pipeline Rotary Control Valves

  • Evaluate performance of PRCV including valve travel, Cv requirements, and estimated acoustic noise predictions

  • Perform semi-automatic sizing of control valves and piping utilizing “Auto Pipe Size” and “Auto Valve” Size features

  • Create cursory design of natural gas regulation facility with adjacent pipe selection, reducer/increase fitting selection, isolation block valve inclusion, and monitor inclusion

  • Evaluate implantation of VRG’s unique below ground control valve application performance for ultimate noise attenuation

  • Perform sophisticated split range control performance analysis for multiple parallel control runs

  • Document your work by saving data analysis for easy retrieval at future date.

  • Print resultant design output to printer or PDF output.  Requires PDF document generator to be installed.
