Dec 04, 2012 Available in 6 and 8 in. sizes, Single Rolling Diaphragm Pressure Reducing Valve provides smooth, steady, and precise pressure control from maximum to virtually zero flow without need for low-flow bypass valves. Effective area of single rolling diaphragm remains constant so bonnet is smaller than flat diaphragm version. By eliminating seat chatter at low flows, SRD avoids injecting small pressure pulses into piping, which, over time, may increase leakage, losses, or pipe bursts.
