Question 24General Subjects - Assistant Engineer

The correct answer is C) Reed. Reed valves are typically used for suction and discharge valves on modern low-pressure air compressors. Reed valves are a type of passive valve that open and close due to pressure differentials, making them well-suited for the suction and discharge functions of low-pressure air compressors. The flexible reed material allows the valve to open and close quickly, providing efficient airflow for the compressor. The other valve types listed (sliding, rotary, and poppet) are not as commonly used in this application.
