REAL LIFE SINGER SOLUTIONS

Their Challenge 

The City of Sheridan, Wyoming needed more control over their water storage tanks and an increase in system redundancy. 

Our Solution 

By repurposing an existing Singer® pressure reducing valve, the city leveraged gravity flow from an upstream treatment plant to fill a water storage tank. They reconfigured the valve operation with instrumentation and automation and realigned buried valves in the yard, bringing this otherwise hidden valve to life in their system. The project saved energy since the booster station was no longer needed to fill the tank but served as a back-up for system redundancy when needed.

The existing Singer Model 106-PR was repurposed to a model 106-2SC-PCO. The valve now has flow and level control, plus the capacity to interact with and be controlled by a Singer control panel using new valve-mounted solenoids that replaced the hydraulic controlled mechanical pilots. An electronic valve position indicator and differential pressure transmitter were also added to the valve.

The Result

Having two options to fill the tank means the city can use real time data to choose to run either option as best suited. The new automation will enable operations to be performed remotely from the control room at the head office.

GREAT 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

“THE DOUBLE DIAPHRAGM VALVE GAVE US THE CONFIDENCE TO MAKE THE INTERCONNECTION AND ALLOW IT TO OPERATE COMPLETELY AUTOMATICALLY”

HOW SINGER ANTI-CAV TRIM MINIMIZES DAMAGE

Their 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

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.”
