MINILUFT HP - 3574

Miniluft HP valves are automatic, float-operated air vent valves designed to remove air and gases from heating or cooling systems.

They are ideal for application on vertical or horizontal columns, on manifolds or boilers, and can be installed in every zone of the system where bubbles may develop. Featuring a small size and high performance (they have a wider pressostatic chamber compared to Miniluft valves), they are very effective in removing air both during filling and emptying, helping you keep the areas on the system where they are installed free from air.

With their high functional guarantee, these automatic air vent valves must be considered a system safety device.

Operating Principle

The accumulation of air bubbles in the upper part of the valve body (air accumulation pressostatic chamber) causes the float descent and, consequently, the gas ejection device opening.

 

For the valve to properly operate, make sure that the water pressure remains lower than the maximum discharge pressure value.
