Dräneringsventilen

Dräneringsventilen, commonly translated as a drain valve or drain cock, is a mechanical device used to control the flow of liquid from a system or container. Its primary purpose is to allow for the controlled release of fluids, often for maintenance, drainage, or to prevent freezing. These valves are typically simple in design, featuring a body, a sealing mechanism, and an actuator.

The sealing mechanism can vary, but common types include a rotating ball or plug that, when turned, aligns a port in the valve body to allow fluid to pass through. Other designs might utilize a simple screw or plunger mechanism. The actuator is usually a handle or a knob that the user manipulates to open or close the valve.

Drain valves are found in a wide range of applications. In plumbing systems, they are used to drain water heaters, radiators, and pipes. In the automotive industry, they are employed in engine cooling systems and fuel tanks. Industrial machinery often incorporates drain valves for the removal of lubricants or process fluids. Their presence is crucial for tasks such as winterization, flushing, or the removal of sediment. The materials used in their construction depend on the fluid being handled and the operating environment, with common options including brass, stainless steel, and various plastics.
