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. The valve body has dual Posi-Stop™ union connections for installation and service efficiency. The 3-wire floating control fail-in-place actuator includes auxiliary contacts, a convenient integral manual override feature and a user- friendly position indicator.
