Their Challenge
At Pepperdine University, even the horses kicked up a fuss about how noisy a nearby valve was when it opened and closed. The horse stable stood next to a reservoir tank in the pressure zone at an elevation of 545 feet. The valve, which was at the tank’s inlet, was serviced by a high pressure line from 812 feet elevation. “The valve vibrated so much it scared us—and the horses,” says Rick LaSance, L.A. County’s electromechanic working supervisor in charge of water distribution. “We were afraid it was out of control.” When the valve needed to be replaced, LaSance knew that specifying the same valve would neither eliminate the noise nor stop cavitation.
Our Solution
When LaSance learned that Singer Valve makes an anti-cavitation product, they decided to try Singer’s Altitude Valve with the Singer Anti-Cavitation Trim at the Pepperdine University tank. “The valve was so quiet we couldn’t believe it,” says LaSance. “There is no more vibration and the horses calmed down.”
The Result
Four years after L.A. County installed the Singer Altitude Valve and Anti-Cavitation Trim, LaSance pulled it apart for inspection. “Everything was running perfectly,” he says. Since then, LaSance often specifies Singer valves. “Any time we have noise in a valve or are working with higher pressure, we go strictly with Singer’s Anti-Cavitation Trim. They solve all of our noise and vibration problems.”
