1.0 INTRODUCTION
On September 17, 1980, a static deflection test was performed on a 4" ITT Grinnell buttweld end diaphragm valve with a model 14NATI Rotork electric actuator. The test was conducted at ITT Grinnell Dia-Flo Division, Lancaster, Pennsylvania, and witressed by two (2)
Duke Power Company representatives. The procedure for the test was covered by ITT Grinnell Report No. 2344, Rev. 2.
Minor deviations to this procedure were made; they have been documented in the text of this report.

3.0 TEST SET-UP The set-up for the deflection test was identical to that described in section 5 of the test procedure with the following exceptions:
a) The valve assembly was mounted in Dia-Flo's de-flection test rig (Fig. 1 ).
Note: valve tras mounted in vertical plane; therefore, the applied force was greater than indicated in section 5.5.
b) Force was applied via loadeell (Fig.3
).
Because the center of gravity of the actuator was not ac-cessible..the tip of the loadcell-was.placed 19.25 inches above pipe centerline.

4.0 PROCEDURE The procedure was as described in section 6.0 of Report No. 2344, with exceptions noted in 3.0 of this report.
5.0 RESULTS 5.1 With the full load (1225 lbs.) applied above the actuator's center of gravity, the valve stroked from the fully open to fully closed position against 150 psi line pressure in 3.4 sec. (Fig. 2).
5.2 The valve was leak tight against 150 psi differential air pressure when closed.
.(
5.3 A copy of the Operability Data Sheet was included in the
'Rasults' section.
