Single rolling diaphragm

Singer Valve has designed an innovative vertical diaphragm that rolls while opening and closing, enabling it to lock the valve in place without any friction. This makes for incredible pressure stability from the highest to the lowest flows unlike flat diaphragm or traditional piston-style valves. By reducing pressure, this valve technology also reduces leakage. The rolling diaphragm reacts faster to changing pressures as it typically has much less water volume above the diaphragm, enabling it to respond quicker. Sizes range from 6" to 36" and are NSF-372 certified.
