How Does a Varivalve Work

A larger orifice allows the air to be pushed out at a lower back pressure. The results show that the larger the vent, the more quickly you can vent a system, which lowers operating pressure requirements.

Should Varivalve be open or closed?

Answer: In the closed position it will still heat the radiator, but at a slower rate. So if the radiator heats so fast, that the room is uncomfortable, you can use the closed position.

How does radiator air vent work?

As the radiator fills with steam it pushes the air out through the open vent. This release of air pulls steam into the vent. The Radiator air valve is heat-sensitive, and ultimately the valve closes trapping the steam in the radiator to heat the radiator.
