Product Description

The volume of the water in the heating system will expand after being heated. Since the heating system is a closed system, when the volume of water in it expands, the system pressure will increase. The function of the expansion tank in the heating system is to absorb the expansion of the system water volume, so that the system pressure does not exceed the safety limit.

When the pressure in the heating system exceeds the limit it can bear, corresponding protective measures must be taken to ensure the safety of the system.  The safety valve is one of the conditions.
