Industrial 79-840B Air Line Check Valve Assembly

The Badger Fire 79-840B Air Line Check Valve Assembly is an inline 1-1/2 inch air-line check valve designed for unidirectional airflow in pneumatic lines. It functions as a one-way valve, allowing air to move in the forward direction while preventing reverse flow to help maintain line pressure and protect upstream and downstream components in compressed-air systems. Identified by the model number 79-840B, this Badger Fire component is part of the company's air-line hardware lineup and is used where backflow prevention is required in air-line runs. The 1-1/2 inch size denotes the nominal connection or bore size for compatibility with common tubing or piping in appropriate installations. As a dedicated air-line check valve assembly, it consolidates the valve and mounting interfaces into a single in-line unit, simplifying installation and service in installations that rely on reliable, one-way airflow. Model identification such as 79-840B helps technicians source replacement parts and reference Badger Fire catalogs for exact specifications and compatibility with their air-line system inventories.
