The Watts 0555180 Check Valve is designed to prevent reverse fluid flow and maintain one-way movement in water distribution and hydronic heating systems. It has a 2-inch NPT threaded connection and a brass valve body for use in specified piping configurations in HVAC systems. It is automatically closed when flow stops or reverses, protect pumps, boilers, and other connected equipment from backflow. Its position within the piping network supports stable system operation by maintaining the intended flow direction and reducing unwanted flow interruption.
