In-line velocity fuse. Male NPTF inlet and female NPTF outlet. Offers full-line shut-off during a line failure. During normal function, a flow below the limit is permitted from port 1 to port 2. If flow rises above the limit it is treated as a line failure and is limited to 2.0 – 3.0 gpm at 3000 PSI.
