Field Controls 094021A0203 Solenoid Fill Valve Assembly 24V

The Field Controls 094021A0203 Solenoid Fill Valve Assembly is a water-flow control assembly that regulates fluid entry into a connected heating or hydronic system through electrically actuated valve movement. When the 24V circuit activates the switch, the internal passage opens to admit water; when power is removed, the passage closes. This action allows automatic management of fluid supply according to signals from the associated control circuit. Placed along the fill-water line, where it regulates flow into the HVAC system during replenishment. In boiler applications, it can work with sensing and control elements to maintain the required water level.
