Pittsfield-Web-PicSINGER ELIMINATES CAVITATION DAMAGE IN PITTSFIELD TOWNSHIP’S RESERVOIR FILLING STATION

Their Challenge 

To address cavitation damage immediately and maintain the current valve functions with controlled programming. The high pressure drop caused by fluctuation in elevation ranges was causing significant cavitation in the plug valve.

Our Solution

Single Rolling Diaphragm with Anti-Cavitation Trim

The Result

  • Cavitation damage eliminated immediately without sacrificing other valves
  • Valve consistently modulating the flow into the tank without any shut down
  • Consistent water flow for the residents of Pittsfield Township
  • SRD allowing the valve to operate steadily at both low and high flows
  • Reduced maintenance thanks to the SRD self-flushing the pilot controls

"THE SINGER VALVE IS WORKING FANTASTICALLY. IT IS A SIMPLE AND EFFICIENT SOLUTION WITH MINIMAL MAINTENANCE."

- Billy Weirich, Pittsfield Township Utilities Superintendent

Malang-Web2

Pressure Management Saves Indonesian City 75% in NRW, Improves Pipe Breakage by 300%, and Reduces Power Consumption by 33%

Their Challenge 

To address high leakage rates, daily pipe bursts and insufficient water levels caused by aging infrastructure.

  • High leakage rates
  • Daily pipe bursts
  • Low reservoir levels due to leakage and pipe bursts
  • Lack of water supply
  • 30% of city's population deprived of water suppl

Our Solution 

138 units of Singer Valve’s S106-2-PR-BT ranging in size from 100mm to 500mm

The Result

  • Reduction of pressure during high demand in the daytime, and further reduction to night time pressure
  • 75% reduction in original water leakage rate 
  • 300% reduction in pipe breakage (thus saving the client money on annual maintenance and repairs)
  • 33% reduction in city power consumption  
  • City of Malang expanded water service to an additional 25,000 connections (amounts to roughly 125,000 people)

"I can sleep well at night knowing the vast majority of customers now have reliable water."

- Mr. Teguh Cahyono, Director of Non-Revenue Water, City of Malang Water Department

yarra-valleySINGER’S SRD VALVE WITH ANTI-CAV TRIM REDUCES YARRA VALLEY STATION FROM 3 VALVES INTO 1

Their Challenge

To prevent cavitation with extreme pressure drop, address the excessive noise, severe erosion, valve damage and downstream pipeline issues - all caused by valve cavitation.

Our Solution

Singer Valve’s 150mm (6") Single Rolling Diaphragm (SRD) fitted with Anti-Cavitation trim

The Result

  • Cavitation problems addressed with the 150mm SRD fitted with Anti-Cav trim (S106-PR-AC)
  • Improved downstream pressure feeding into residential homes with better stability
  • Removed the need to protect the other two valves with Anti-Cav trim as one valve can handle entire flow range 
  • Less maintenance required in the future

"ANOTHER ADVANTAGE THAT IS SIGNIFICANT OVER TIME IS THAT WE NOW HAVE FEWER ASSETS REQUIRING LESS MAINTENANCE."

Malaysia301-4_tnailSINGER VALVE'S ALTITUDE PILOT STOPS MALAYSIAN RESERVOIR OVERFLOWING

Their Challenge

To ensure that the state's water infrastructure is reliable and effective.

Our Solution 

Singer Valve’s 301-4 Atltitude Pilot.

The Result

Singer Valve's 301-4 Altitude Pilot reduced reduced the number overlows in the reservoir, increased the supply of revenue-generating water and reduced repair costs because the valve body can be serviced without removing the pilot and the inner valve can be replaced without disconnecting the pilot tubing.

Singer Valve's Algorithm Controls Farm Irrigation

San-XavierSINGER'S ALGORITHM CONTROLS FARM IRRIGATION

Their Challenge

On the San Xavier Reservation near Tucson, Arizona, the Tohono O’odom Nation grows organic alfalfa for racing horses plus fruits and vegetables. Thanks to Singer Valve, San Xavier is home to a sophisticated flood irrigation system that consists of one 16” (400 mm) globe style and eight 16” angle style valves and five storage tanks each with its own control panel. Controlling flow intake, high pressure and each tank’s water level electronically and simultaneously throughout the entire system, however, was not easy. “Water is piped to the first tank at 120 psi (8.3 bar),” says Dave Buchwald, a fluid dynamics specialist with Pipestone Industrial, a Singer Valve representative based in Denver. “But, it can’t flow more than 10,300 gallons per minute (650 L/sec), which would exceed the water right limit, and, to feed the relatively small storage tank, pressure has to drop to about 5 psi (0.34 bar).” One 16” valve at the first storage tank, which is only 25’ (7.6 m) in diameter and 12’ (3.7 m) tall, was equipped with a flow limiting function and Anti-Cavitation Trim. Each subsequent tank (15’ x 12’ or 4.6 m x 3.7 m) is equipped with 16” valves. Along the pipeline are delivery valves that open to flood the various fields. To flood the fields adequately, however, each of the five tanks must be able to handle up to 10,300 gpm as well as maintain a specified water level. Coordinating both functions at each of the five tanks simultaneously was the ultimate challenge.

Our Solution 

Singer Valve built a simulator so it could mimic the behaviour of the San Xavier irrigation system. After testing a standard PID (Proportional Integral Derivative), Singer Valve wrote a custom algorithm for PLC (Programmable Logic Controller) that stabilized water levels within a few minutes compared to the standard PID’s performance of two days.

The Result 

Thanks to Singer Valve, San Xavier is home to a sophisticated flood irrigation system that consists of one 16” (400 mm) globe style and eight 16” angle style valves and five storage tanks each with its own control panel.

“THIS WAS A VERY COMPLICATED, VERY UNUSUAL APPLICATION, AND IT WAS VERY SUCCESSFUL. SINGER VALVE GETS A GOLD STAR.”
