Eclipse 501223 3/4 Inch Npt Full Port Btrfly Valve

The Eclipse 501223 is a 3/4-inch, full-port butterfly valve intended for use in a variety of air and gas flow applications, including combustion systems found in HVAC equipment. The airflow is controlled by a disc on this automatic control valve, which rotates 75 degrees. It is not intended to totally stop flow, as a shut-off valve would, but rather to control the flow rate by shifting the position of the disc. Maintaining the best possible combustion efficiency and safety in boilers, furnaces, and other gas-powered heating equipment depends on this regulated flow. The Eclipse 501223's autonomous functioning facilitates its interaction with many control systems, hence providing accurate regulation and automation of the combustion process. This can result in greater fuel efficiency, lower emissions, and better overall system performance.
