How do noncompression faucets regulate the flow of water?

Noncompression faucets regulate the flow of water by using movable discs. This design helps to create a tight seal that prevents leaks and allows for precise control of water flow. The mechanism consists of two discs that can slide over each other, effectively managing the opening and closing of the water flow. When one disc is moved, it either exposes or covers an opening, which determines how much water can pass through. This system contrasts with compression faucets, which rely on rubber washers and require the user to tighten the handle to stop water flow. By utilizing movable discs, noncompression faucets offer a smoother operation and greater durability, as there are fewer components that can wear out over time.
