Eclipse 501229 3 Inch Npt Full Port Btrfly Valve

The Eclipse 501229 is a 3-inch automatic full-port butterfly valve designed for use in a wide range of HVAC (Heating, Ventilation, and Air Conditioning) systems. It has a disk-shaped closure that rotates to regulate the flow of air or gas. Unlike some butterfly valves, the 501229 has a "full-port" design, which means the diameter of the opening through the valve when fully open is the same as the diameter of the pipe it is installed on. This reduces pressure loss while the valve is open. The automatic version of the 501229 is intended to be controlled by an external actuator (not included), allowing for remote control or integration with building automation systems. It is frequently found in air handling units, chillers, and cooling towers, where it is used to regulate airflow.
