Automatic air vent

The solution is the vent valve against damage to the water system.

The presence of air in a water system represents a common problem that must be addressed with the use of a vent valve to avoid damage to the system itself, both because it causes corrosion and because it can cause cavitation in the pump. When the air, in the form of bubbles, enters the body of the relief valve, it causes the float connected to the shutter to move downwards.

The shutter also lowers, letting the air escape to the outside. Once the air has been drained, the water pressure causes the float to return to the starting position and the shutter closes.
