High Airflow Shut-Off On/Off Valves
Also known as air fuses, these valves close automatically to stop airflow when air volume exceeds the shut-off flow rate. They have NPTF (Dryseal) threads that are compatible with NPT threads.
Flow coefficient (Cv) is a measurement that indicates how much airflow can pass through a valve.
