Atlas Copco Group acquired Zahroof Valves Inc. (Zahroof) in 2024 (see “Atlas Copco Group Acquires Zahroof Valves,” April 2024 Gas Compression Magazine, p, 26). The company’s StraightFlo valve is a drop-in replacement compressor valve that is made up of replaceable reed valve modules designed so that the gas flows essentially in a straight line through the valve. The StraightFlo valve has a design where several standard and interchangeable modules are held stationary between the valve seat and carrier.
Following the acquisition, Zahroof became part of Atlas Copco’s Compressor Technique Business Area, operating under Atlas Copco Compressors LLC as Atlas Copco StraightFlo Valves.
