Successful Seismic Testing for Flowserve Valves
Monday, November 2, 2009
World Pumps - Both the Flowserve Durco extended
bonnet cartridge plug valves and Flowserve McCanna top-entry cartridge ball
valves passed the stringent seismic testing on the first attempt. Each valve
was cycled 16,000 times with pumped simulant flowing at 150 psig. Seismic tests
included a 0-100 hertz resonance search, followed by six random-frequency,
independent-excitation triaxial seismic tests with up to three-G acceleration. More…
