This is a utility for selecting and sizing Flowserve-Edward
valves and is an interactive version of the catalogs
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
for additional check valve application
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
Flow Noise calculations are highly approximate.
