EValSz(2.5x)
Selection Program for
Flowserve-Edward Valves

SCOPE

This is a utility for selecting and sizing Flowserve-Edward valves and is an interactive version of the catalogs FCD-EVENCT0001 and FCD-EVENCT0002  which provide further defining details including underlying theory.

DISCLAIMER OF LIABILITY

This program is for general guidance to Flowserve-Edward customers. In all cases the customer is responsible for confirming the accuracy and usefulness of the results obtained from the program. In no event shall Flowserve-Edward or its affiliates incur any liability arising out of the use of this program or the results obtained therefrom. Use of this program shall be deemed to be your acceptance of these conditions.

ACCURACY OF PRESSURE DROP AND LIFT ESTIMATES

Pressure drop and check valve lift estimates are best estimate values, based on standard pressure drop equations of the Instrument Society of America (ISA), flow rate and fluid data provided by the customer, and valve flow coefficients provided by Flowserve-Edward.

Check valve lift estimates assume installation in horizontal piping with the bonnet or cover oriented vertically upward. See Flowserve-Edward Catalog FCD-EVENCT0001 or FCD-EVENCT0002   for additional check valve application guidelines.

Flow and check valve lift coefficients for Flowserve-Edward Valves are based on results of laboratory testing. Valves of each specific type are tested, and results are extended to sizes not tested using model theory. Uncertainties prevent a guarantee with regards to valve pressure drop and lift performance. However, estimates are expected to be accurate within +/- 15%, with most within +/- 10%.

Flow Noise calculations are highly approximate.
