Vent valve

A vent valve is a ventilation element that is used to remove air from closed systems, especially from systems with liquid circulation, such as heating systems, cooling systems, radiators, or water heaters. Its main function is to allow efficient and rapid venting to prevent the formation of air bubbles inside the system.

Whenever the system is filled with new fluid or fluid is lost during operation, air can be trapped in the system. The presence of air bubbles can reduce the efficiency of the system, cause blockages or irregular fluid flow, and in some cases can cause corrosion or other problems.

The bleed valve works on the principle that air, which is lighter than liquid, accumulates at the highest point in the system. The valve is located at this highest position, and when air builds up there, it opens and allows the air to escape from the system. This removes air bubbles and makes the system work more efficiently.

Bleed valves are often used in systems with circulating fluid, such as radiators in heating systems, to ensure that the fluid is always clean and free of air. In some cases, vent valves can be automatic, meaning they open and close depending on the presence of air, or they can be manual, opening by hand.

Bleeding valves are an important part of many systems and ensure their trouble-free operation and longer service life.
