Which valve can go from fully open to fully closed with a 1/4 turn?

The valve that can move from fully open to fully closed with a 1/4 turn is the plug valve. Plug valves are designed with a cylindrical or tapered "plug" that fits into a similarly shaped cavity within the valve body. This design allows for quick and efficient operation, enabling the valve to either allow or restrict flow with a simple quarter-turn of the handle.

Plug valves are often used in applications requiring tight sealing and quick operation, which makes them suitable for many water distribution and control scenarios. The design and operation mechanism substantially differentiate them from other types of valves, such as gate, check, or ball valves. While gate valves typically require several turns to close completely, check valves allow flow in one direction and cannot be fully closed with a quarter turn, and ball valves, although they do operate with a quarter turn, do not fit the specific context as well as plug valves do for certain operational scenarios.
