Sizemaster
Now you can accurately size and select a pressure relief valves for any combination of process applications with SizeMaster™ Mark IV pressure relief valve engineering software. This program for Windows® (all versions) brings unprecedented integration of standard engineering practice to the task of sizing and selecting pressure relief valves.
A User Account is required to access updates to the Sizemaster Software.
If you already have an account please click here »
With SizeMaster Mark IV software, you can define as few as one or as many as 64 different sizing scenarios including blocked flow, fire, thermal and tube rupture, from a scenario matrix grid. Selection of the pressure relief valve is automatically based on the relief area of the worst case scenario. Various Wizards make the most complicated task simple; for instance, the Capacity Wizard allows you to determine accurate vapor generation for vessels of all types.

All sizing equations and selection algorithms are based on ASME Code requirements, API standards and best engineering practice as determined by Farris Engineering. The equations and flow algorithms are internally calculated within an innovative worksheet engine. This worksheet engine also checks parameters and any intermediate calculations against standards’ constraints, letting you know about any non-compliance issues it encounters. All equations, calculations and internal algorithms can be displayed on screen or printed for review.
The engineering worksheet engine also checks your parameters and all intermediate calculations against the standards’ constraints, and it tells you about any non-compliance that it encounters, such as attempting to size a conventional valve when a bellows valve is required.
Once SizeMaster calculates the orifice area required to relieve your process scenarios, SizeMaster guides you through the selection of the appropriate Farris pressure relief valve and its materials and other options.
During selection, SizeMaster recommends the optimum pressure relief valve for each Farris valve series that is applicable to your process parameters.
SizeMaster includes catalogue information for Farris 2600, 2700, 3800, 6400, 6600, 4200, 2800 , and 7200 series pressure relief valves, including their black and white drawings. While you are selecting a Farris type number for a tag, SizeMaster ensures that you don’t pick a valve that is not applicable to your process parameters (such as a liquid-service valve for a vapor scenario), and on-line help is available to assist in the determination of each of the digits of the Farris type number, based on your process scenarios.
SizeMaster manages the entire sizing and selection work-flow process for jobs and tags, from request for quotation through order generation.
From its Quick Size and Capacity Wizards through to its consistently standard Windows user interface, SizeMaster makes the job of sizing and selecting pressure relief valves easy, and its worksheet management and workflow auditing facilities let you ensure that your results are correct.
SizeMaster covers the bases, from its Installation and Workstation Configuration Wizards through to its integrated database administration facilities.
