Their Challenge
Sergio Mendonça was troubled. How could he reduce the municipality’s water losses by controlling the pressure and flow of its major pipelines? One source of São Bernardo do Campo’s water supply is 120 metres above four residential suburbs. During the day, the water pressure was sufficient due to the high demand. At night, with reduced customer demand, the pressure would increase substantially. And, because the main supply lines were manually closed, they would often leak or break.
Our Solution
After hearing about São Bernardo’s problem, Alejandro Duque, Singer’s territory manager, introduced Mendonça to Singer’s Pressure/Flow Control Valve. Comparing Singer’s product and another brand, Mendonça looked at each valve’s specifications, price, availability, ease of installation and performance. The winner? Singer’s PFC Valve.
The Result
When São Bernardo installed five Singer PFC valves, Mendonça documented the results and the savings. After two months, studies showed that water loss had been reduced by 15 per cent; the economic savings were just as great. And the results continued even after one year. “The PFC pilot is a simple, reliable device that you can easily maintain,” says Brian Blann, president of Singer Valve Inc. “Although it’s used to solve water loss applications, the PFC is ideal in maintaining pressure at a distant point without any electrical requirements because it functions 100 per cent on hydraulics.”
