Product Description

The Balance VII is a stainless steel expansion joint with stainless steel weld ends. It is used to accommodate axial movements and relatively small lateral misalignments in piping systems. Due to its double-ply bellows, this compensator is more flexible in comparison to similar single-ply compensators. The maximum operating temperature of the Balance VII is +550 °C, the maximum working pressure 2,5 bar (120 °C).
