Hahnventil

Hahnventil is a German term that translates to "tap valve" or "faucet valve." It refers to the internal mechanism within a faucet or tap that controls the flow of water. This component is crucial for regulating both the volume and temperature of water dispensed from a fixture. While the term is general, it most commonly refers to the valve assembly located inside the handle or stem of a faucet.

There are several types of Hahnventil, with the most prevalent being compression valves and cartridge valves. Compression valves, found in older faucet designs, use a rubber washer that is pressed against a valve seat to stop the water flow. Cartridge valves, common in modern faucets, contain a movable stem that directs water through different ports to control flow and temperature. Ceramic disc valves are another type, utilizing two ceramic discs that slide against each other to open or close the water passage, offering durability and precise control. The proper functioning of the Hahnventil is essential for preventing leaks and ensuring the smooth operation of any water tap.
