Great Things Accomplished When Two Townships Team Up with Singer Valve

Millcreek-PR-SM-3GREAT THINGS ACCOMPLISHED WHEN TWO TOWNSHIPS TEAM UP WITH SINGER VALVE

Their Challenge 

To maintain an effective and reliable water system for a growing customer base and commercial district

Our Solution 

Singer Valve’s Pressure Reducing Valve with Integral Back-up (PR-SM). The PR-SM control valves have a second and independent operating system superimposed upon the standard primary system. Under normal pressure reducing conditions, the primary pilot senses the downstream pressure through a connection at the valve outlet. Under flowing conditions, the pilot reacts to small changes in pressure to control the valve position by modulating the pressure above the diaphragm in the lower operating chamber. The downstream pressure is maintained virtually steady at the pilot set-point which is adjustable.

The Result 

Continuous water pressure to MTWA's customers even during power outages

How Singer Anti-Cav Trim Minimizes Damage

HOW SINGER ANTI-CAV TRIM MINIMIZES DAMAGE

Singer Valve 2SC-PCO fitted with Anti-Cavitation TrimTheir Challenge

Pumping water at 5,310 g/m (335 l/s) with pressure beginning at 60 psi (4.1 bar) and dropping to atmosphere, it’s no wonder the City of Airdrie’s reservoir fill valve had to be replaced regularly due to serious cavitation.

“We inspected the reservoir fill valve every year for damage due to cavitation,” says Kelly McKague, City of Airdrie’s facility operator. “The valve was completely eaten away so we had to replace it every 18 months.”

Our Solution 

McKague decided to purchase a 12” (300 mm) Singer 2SC-PCO fitted with Singer’s Anti-Cavitation Trim. Singer Valve customized the cavitation cages to suit Airdrie’s application. Curious about its performance, McKague inspected the valve six months later. “We could have boxed the valve and resold it,” says McKague. “There was absolutely no sign of cavitation, not even on the coating. We couldn’t believe it.”

The Result 

One year after installation, McKague inspected the valve again and saw no signs of damage whatsoever. Another benefit of the Singer Anti-Cavitation Trim is the noise reduction. Because cavitation is noisy—like gravel going through the valve—with the Anti-Cavitation Trim, the valve is amazingly quiet.

“THE SINGER 2SC-PCO WITH SINGER’S ANTI-CAVITATION TRIM IS DEFINITELY THE RIGHT VALVE FOR THE JOB.”

Singer Pilot Guarantees Water to Desert Pilgrims

saudi-arabia-singer-projectSINGER PILOT GUARANTEES WATER TO DESERT PILGRIMS

Their Challenge

To accommodate pilgrims who overnight in the Mina Valley during the annual Islamic pilgrimage, the government of Saudi Arabia provides shelter in residential towers and tents. One of the housing projects was plagued with multiple broken pipes and a dysfunctional pressure reducing valve, resulting in floods. Upon inspection by Singer Valve’s Ramzi Soujah, it was discovered that the pressure reducing valves required up to six turns before a pressure change was noted downstream. Also, the pilots’ sensing ports were extremely small and susceptible to being plugged by dirt and mineral build-up.

Our Solution 

Ramzi Soujah replaced the faulty pilot with a Singer Model 160 Pressure Reducing Pilot. The pilot has a non-clogging pilot guide stem above the diaphragm, which is totally removed from the flow of water in the main pilot chamber. Because the outlet is located in the bottom of the pilot, 90 degrees to the inlet, the pilot is self-cleaning and self-flushing, thereby eliminating debris build-up. The pilot was the ideal solution for the Mina housing project.

The Result 

As soon as the pressure reducing valve was installed, the valve began to regulate the pressure. After observing such positive results, the housing contractor purchased Soujah’s entire stock of Singer Model 160 Pressure Reducing Pilots.

“I WAS EXTREMELY PLEASED WITH THE QUALITY AND DESIGN OF THE SINGER PILOT. THE PILOT HAS OPERATED BEAUTIFULLY EVER SINCE.”

Singer's Specialty PRV Regulates Bangkok Pressure

Posted by RS

Sep 19, 2018 5:35:12 PM

application-story-bangkokSINGER'S SPECIALTY PRV REGULATES BANGKOK PRESSURE

Their Challenge

With water loss up to 30 per cent, Metropolitan Water Authority (MWA) in Bangkok, Thailand, installed pressure reducing valves throughout the city and its suburbs. The valves controlled nighttime pressures accurately, preventing leaks and breaks. However, in some areas, high demand during the day caused the pressure to drop to 10 psi (0.68 bar) or less. Without sufficient pressure differential, regular pressure reducing valves would close, cutting off supply to consumers.

Our Solution

Because typical PRVs cannot open when the pressure drops below 10 psi (0.68 bar), Singer Valve’s instrumentation specialist Eugene Bahia fitted a 12” (300mm) valve with a standard Singer PR pilot and a Singer high-accuracy three-way pilot. By installing the custom combo into Singer’s flow lab, Bahia simulated various pressure and flow conditions. The results were rewarding.  “Because of the large diaphragm and sensing area of the three-way pilot,” says Bahia, “the valve required only seconds to open. And it remained fully open during the day’s high flow demands even with pressure as low as 2 psi (0.14 bar).”

The Result

When the custom unit was installed and tested in Bangkok, the results remained consistent. Pressure was reduced during high pressure periods at night. During low pressure / high flow periods in the day, the valve opened fully, ensuring a constant water supply to consumers. As a result, the water authority has installed numerous 12” (300mm) valves. “Our water loss was about 30 per cent,” says Mr. Ulit, MWA’s director of water loss management. “With Singer Valve, it’s now below 30 per cent.”
