Full-way valves are also called shutoff valves.

Full-way valves are also called shutoff valves.

• A. True
• B. False
• C. Not applicable
• D. Sometimes

Answer: (A)

Full-way (full-port) valves are built so that when they’re open, the bore matches the pipe diameter, allowing unobstructed flow. They can also be fully closed to stop all flow, which is exactly what a shutoff valve does. So a full-way valve functions as a shutoff valve because it provides a complete on/off capability. Keep in mind that some shutoff valves have reduced bore and restrict flow when open, but they still serve the shutoff purpose; the full-way type simply offers minimal resistance when open.
