Viega’s automatic recirculation balancing valve ensures a balanced domestic water recirculation system by dynamically changing with varying conditions, the company notes. The valve is a modification of a Viega product that has been used successfully in Europe for years, it adds. It helps keep water temperatures more uniform by adjusting flow with changes in temperature. The results are faster hot-water delivery, minimized waste energy and water, and less stagnation and chance of contamination, Viega explains. Among the valve’s features, Viega notes temperature can be set once and be automatically maintained. Settings also can easily be changed, if needed. The valve can be installed on risers or branches, and includes bypass for thermal disinfection. Threaded ends allow it to be used with Viega ProPress or Viega PureFlow fittings systems.
