HYDRAULIC FEATURES

This
automatic air vent valve is a single float valve designed for solar
thermal energy plants, and carries out two main functions: the
evacuation of a consistent air flow through the system (e.g. during
loading/pressurization of the plant), and degassing which discharges air
trapped in the pipeline, while functioning, in particular in the solar
collectors. This valve has a paramount importance in solar thermal
energy plants, evacuating and discharging trapped air in the pipelines
and in the solar collectors. As a matter of fact, the presence of oxygen
in the system can provoke numerous negative phenomena such as anodic
corrosion, localized noise, air pockets, obstructions, etc., which may
significantly compromise the performance and integrity of the systems.
These valves are usually installed at the summit of the primary circuit
in a solar thermal energy plant, and are resistant to the high
temperatures that the heat-transfer fluids can reach, even in stagnation
phases. Their suitability for application in solar thermal energy
plants conforms to EN 12976 and EN 12977.
