Description
The 638 series high flow 2-way motorized ball valves are perfect for shutoff and isolation in hydronic heating or cooling applications. Bubble-tight sealing, high differential pressure closeoff and significant Cv flow coefficients make the 638 series ideal for application in large-scale hydronic and geothermal systems.
