Application
Ball valves can control hot or chilled water and up to 50% glycol solution in mixing
applications for air handlers, convectors, fan coil units, unit conditioners, radiation, and
reheat coils. Three-way ball valves can be piped for either mixing or diverting
applications. See Figure 1 and Figure 2 for piping configurations for mixing and
diverting applications, respectively.
