Lisäajovalot are a type of valve used in plumbing and sanitation systems. They are designed to allow air into a pipe or system, while preventing the flow of liquids in the opposite direction. This is achieved through a specific internal design, which creates a small, precise flow restriction.
Lisäajovalot are typically used in applications where a high resistance to backflow is required, such as in
Backflow valves like lisäajovalot rely on the interaction between opposing forces created at the moment when
