In all heating systems using a liquid as a heat carrier, various gases are formed from the air in a dissolved state. These gases lead to various equipment malfunctions, extraneous noise, coolant circulation problems and premature system corrosion. To avoid these problems, Giacomini
developed a special automatic air vent valve.
The R88 series valve has a high gas removal dynamics, it has small dimensions, which allows it to be used in confined spaces. The ventilation mechanism is reliable, each valve undergoes three tests before sale: two for the degassing mechanism and one for pressure.
Suitable for work in environments that are not corrosive to copper alloys.
