1.0 TEST REQUIREMENTS The Masoneilan International Butterfly Valves, 10" Model 69-32200, 20" Model 71-32112 and 36" Model 69-3220, are required to pass the seismic vibration test specified in para. 2.0 without evidence of mechanical damage or deteri-oration.
The valves shall be pressurized during the seismic vibration test.
Responses of the valves shall be monitored during the simulated seismic event.
2.0 TEST PROCEDURES The Masoneilan 10" Butterfly Valve, Model 69-32200, with Masoneilan Model 496 switch, was mounted to a test fixture.
The test fixture/test item assembly was mounted to the movin9 tabl~ of the Acton Environmental Testing Corporation (AETC} single axis seismic test facility for vibration in the side-to-side axis.
Four (4) strain gages were mounted to the valve in the following locations:
1 right sjde of gear housing sensing side-to-side 2
left side of g~ar. housing sensing side-to-side 3 '- butterfly. housing limit swi.tch end front-to-back 4 - coupling between_ gear and valve housing sensing vertical A nitrogen line was connected to the valve to pressurize the valve to 50 psi.
A second ni~rogen line hdS ~onnected tu the actuator inlet to pressurize the actuator to 90 psi~
Seven (7) acceleroJTieters \\'/ere mounted to the valve *as follows:

The resonance survey of this valve and all subsequent valves was performed with the valve in the OPEN POSITION.
The following resonance survey was performed:
1-25 Hz, 0.2g's peak, l octave/minute sweep rate.
Following completion of the resonance survey, sine beat vibration tests were performed at all resonance surveys at a test level of 3.0g's peak.
5 beats. 10 cycles/beat with the VALVE OPEN and again with the VALVE CLOSED, or if no resonance were found, at l.Og's peak, 5 beats, 10 cycles/beat with the VALVE OPEN and again with the VALVE CLOSED.
Following completion of the resonance survey and sine beat vibration test in the side-to-side axis, the test fixture/
test item assembly was rotated on the AETC test facility for vibration in the front-to-back axis.
Accelerometers and strain gages remained in the same posi-tion and the above specified test was repeated.

test item assembly was remounted for vibration in the vertical axis with all accelerometers and strain gages in the same locations and the above specified test was re-peated in the vertical axis.
After completion of the above series of tests on the 10" Butterfly valve, the above specified test series was re-peated on the 36" Butterfly valve and 20" Butterfly valve.
Strain gage and accelerometer locations for the 36 11 Butter-fly valve were positioned as follows:
l - Sensing vertical front face gear actuator housing 2 - Sensing vertical back face gear actuatrir housing 3 - Sensing* vertical limit end of valve side housing 4 - Sensing front-to-back limit end of valve side housing 5 -

The tests specified above for the 10" valve were performed on the 36" valve.
Following completion of the resonance surveys and the sine beat Yibration tests on the 36" valve, the 20" Butterfly valve was mounted to its test fixture and the test fixture/
test item assembly was mounted to the moving table of the AETC seismic test facility.
Four strain gages were mounted to the valves in the follow-ing locations:
