Singer Valve introduced the revolutionary rolling diaphragm design to the automatic control valve industry in 1983. Although rolling diaphragm technology has been used in railway air brakes for more than a century, Singer is the only pilot oper-ated control valve company to adapt the technology for control valves. With water loss management a global priority and the accompanying need for precise pressure management, Singer Valve’s pioneering design and engineering is leading the way.
Since the first Singer rolling diaphragm control valve in 1983 to the introduction of the rolling diaphragm technology on 6" (150 mm), 8" (200 mm) in addition to our existing range from 10" (250 mm) to 36" (900 mm), Singer has been steadfast in its dedication to offer precise pressure management. The advantage of rolling diaphragm technology in contrast to flat diaphragm, or traditional piston-style valves, is the incredible stability through-out a complete range of flows.
Singer’s rolling diaphragm can control pressures with flows as high as any prod-uct offering in the marketplace today; however, the Singer difference is on ex-tremely low flows. During the night most distribution systems have low flow and higher pressures. Traditional automatic control valves will often have seat chat-ter. At low flows the valve will chatter and vibrate. As a result, a smaller bypass valve is needed to control the lower flows. A Singer rolling diaphragm pressure reducing valve will provide stable, reli-able and precise pressure control from

Rolling Diaphragm: Proven TechnologyIn 1880, the Rolling Diaphragm Technology was utilized by Westinghouse Air Brake Company in its railway air brakes. Singer Valve adapted and then incorporated the technology for the Automatic Control Valve industry in the 1980s.
Why Customers Are SwitchingTo Single Rolling Diaphragm Technology
Save the cost, space and complication of bypass valves in your Pressure Reducing Sta-tions.
The 6″ (150 mm) and 8″ (200 mm) S106-PG (SRD) design controls down to the lowest industry published flows* (substantially lower than industry published competitive low flow data) with no hunting or seat chatter. These valves have been added to our single rolling diaphragm technology from 10″ (250 mm) up to 36″ (900 mm). *Tested in our lab over a wide range of inlet and outlet pressures.
Pressure management can be one of the most cost effective methods in reducing water loss. The Singer S106-PR (Single Rolling Diaphragm) Pressure Reducing Valve provides smooth stable pressure from the minimum night flows up to your maximum peak flows. By eliminating the seat chatter at low flows, the SRD avoids injecting small pressure pulses into the piping, which, over time, may increase leakage and losses as well as pipe bursts.
Metering applications are becoming popular utilizing diaphragm operated control valve technology. The use of Singer Rolling Diaphragm Technology is becoming an industry requirement to ensure stability and accuracy of measurement at low flows.
How Does It Work? Effective area of a single rolling diaphragm remains constant so the bonnet is much smaller and lighter than a flat diaphragm version. Measured quantity into bonnet control chamber always gives the same smooth movement of inner valve through the entire stroke.
Proven science. Proven engineering. Proven results.
District Metered Area (DMA) Control Finally, a diaphragm control valve ideal for water loss and leakage while providing stable control down to the lowest flow.
