The Bosch 87085050230 is a motorized water valve that manages hot water flow inside HVAC and hydronic heating equipment, opening, closing, or rerouting circulation on signal from the appliance control so the system can shift between heating and domestic hot water duty without manual intervention. Built on a glass reinforced polymer body with multiple flow ports, it carries an integrated 24 VDC gear motor actuator in a white housing that mounts directly to the valve body through a steel bracket and terminates in a short four wire harness with a keyed plug, keeping the electrical and mechanical halves together as one calibrated unit so there is no separate actuator to fit, align, or set during installation. Cataloged as model T405-187R and rated for fluid temperatures up to 80 degrees C, it suits the operating range of typical residential and light commercial heating circuits, and it arrives with fresh O-rings and stainless steel retaining clips so each port can be resealed and locked in place during the same service visit.
