In-line velocity fuse. Female NPTF inlet, male NPTF outlet. Full-line shut-off during a line failure. During normal operation, a flow below the limit is permitted from port 1 to port 2. If a line failure occurs, flow is limited to 2.0 – 3.0 gpm at 3000 PSI. Flow from port 2 to port 1 passes through the controlling orifice but is uncontrolled.
