Waste water air valve with three functions :
- Function 1: High-flow air intake to protect the installation when the pipe is being drained or when there is a drop in pressure due to a burst pipe.
- Function 2: High flow air evacuation during filling phases.
- Function 3: Pressurised degassing to evacuate air pockets during operation or following a change in temperature and/or pressure.
Applications :
- Waste water.
