3.2 |
4-08-19 |
Corrected valve identification and piping selection errors in Drop/Flow calculation forms. This is a catch up from 3.0 changes. |
3.1 |
3-28-19 |
Improved validation in the Single Valve Pressure Drop page RE saturated Steam. To improve future bug identification, un-trapped errors now spawn the standard error page. |
3.0 |
2-26-19 |
Improved validation RE materials. Worthy of a new version, introduced a better page save state scheme which will end timeout issues (RE version 1.7). |
2.7 |
12-14-17 |
Corrected rating table to stop at B16.34 temperature limit (e.g., for F347). |
2.6 |
08-18-17 |
Updated to B16.34, 2017 Ed. Added Size 10 to 16 class 2500 forged flite-flow valves. |
2.5 |
01-20-17 |
Valve Options Page bug fixes RE F316, F316L, false positive valve list when no pressure class is applicable. |
2.4 |
08-12-16 |
Disabled viewing of valve drawings until such time as they are updated to the current state. Removed Size 3 and 4 Flite-Flow valves with intermediate Pressure Classes equaling 400, 700, 1100, 1800, and 2900. |
2.3 |
06-15-16 |
Fixed required pressure class and valve list inconsistencies in ValveOptions page. |
2.2 |
03-08-16 |
Improved robustness and corrected valve labels in Two Stop Valves in Series page. Fixed inlet/outlet pipe I.D. verification for venturi valves. Fixed figure link submit problem on ValveSelection page. |
2.1 |
08-21-15 |
Added size 2 and 2.5 SWE Continuous Blowdown valves for orifices #2 through #10. Fixed issues with the display of flow coefficient curves. |
2.0 |
04-15-15 |
Improved database access stability. EValSz is now compatible with all major browsers. |
1.8 |
03-05-15 |
Addressed compatibility automatically for IE 10 and above. |
1.7 |
12-08-14 |
Added automatic page refresh every 15 minutes to avoid session timeouts. |
1.6 |
5-28-14 |
Improved data validation messages. Changed pressure-temperature rating rounding to be consistent with the catalog. |
1.5 |
3-20-14 |
Updated to ANSY B16.34, 2013 Edition, but no data changes are required. Fixed I.D. drop-down bugs RE validation and size change. |
1.4 |
3-28-13 |
In ValveOptions.aspx, added 'Rating Tables' Option, valves are now sorted by
figure, now non-default materials are processed only upon selection change, and
corrected calculation of metric-derived pressure class for T < 100OC. Enabled venturi option for gate valves
in pressure drop calculations. Corrected 'SER Class' to 'Series' in calculation forms. |
1.3 |
4-20-12 |
Ratings for the Limited Pressure Class are now derived directly from special class tables
(with 'y' interpolated conventionally), rather than from Flowserve-derived tables.
Added validation of flow data availability.
Corrected metric special class pressure rating table for 347 & 347H.
Corrected units issues in ValveFlowOptions.aspx. |
1.2 |
12-10-11 |
In ValveDropOptions.aspx, ValveDropOptions2.aspx, and ValveFlowOptions.aspx, corrected connecting piping options behavior regarding NPS selection.
Corrected Cv calculation error when ValveFlowOptions.aspx was the session's first accessed form. |
1.1 |
9-6-11 |
In ValveDropOptions.aspx, added missing Cv and Fp
for 100% open and added turndown ratio for disk skirted valves.
Corrected data persistence from ValveOptions.aspx to other forms. Added catalog page links in calculation pages. |
1.0 |
8-3-11 |
Released the initial issue to replace and enhance previous versions, which were available per CD or download from Flowserve.com |
