Which term describes a non-compression single-handle faucet with hot and cold water openings?

Explanation:
Port-control describes a non-compression single-handle faucet that uses internal ports in the valve body to mix hot and cold water as the handle is turned. There’s no rubber washer being compressed to stop flow; instead, the control element aligns ports to allow or restrict water from the hot and cold inlets, giving you the desired temperature and flow. This distinguishes it from compression faucets (which seal with a washer), ball-type faucets (which use a rotating ball), and cartridge faucets (which rely on a cartridge).
