    Lead is one of the most pressing challenges communities face in protecting public health in the face of aging water infrastructure. Clear and without taste or odor when dissolved, lead in drinking water poses major health risks, especially for growing families. Ingestion by small children can cause permanent brain damage, resulting in lower intelligence and medical problems for the rest of their lives.

  • Getting Down To The Nitty Gritty

    It has been said that the unseen and untreated can break down any system — this phrase could not be more accurate than in the world of wastewater treatment when considering the infiltration of grit into a system. Infiltration happens in the collection system, whether it’s from living on the coast, aging infrastructure or just plain old build up over time.

  • Improved Detection Key To Tackling Organic Contamination Issues

    For many applications, water should be free — or nearly free — of organic compounds. In drinking water, the impact is optimal taste, appearance, and safety. While the problem of organics finding their way into source water continues to grow, newer monitoring technology is making it easier for water treatment plants to rapidly detect the substances and apply the appropriate fix.

Single Rolling Diaphragm Pressure Reducing Valve Single Rolling Diaphragm Pressure Reducing Valve

The SRD Pressure Reducing Valves provide smooth, steady and precise pressure control from maximum to virtually zero flow without the need for low-flow bypass valves. The effective area of a single rolling diaphragm remains constant so the bonnet is much smaller and lighter than a flat diaphragm version. A measured quantity into the bonnet control chamber always gives the same smooth movement of the inner valve through the entire stroke. A smaller bonnet also makes the valve lighter and safer for maintenance, while the smaller control chamber enables it to respond faster to changing pressures. By eliminating the seat chatter at low flows, the SRD avoids injecting small pressure pulses into the piping, which, over time, may increase leakage, losses or pipe bursts.
