Product Description

The Balance IV is a relatively short stainless steel expansion joint with carbon steel weld ends. It is used to accommodate axial movements and lateral misalignments in piping systems in situations with limited installation space. Despite its short length, it can accommodate small lateral movements. Due to the double-ply bellows, this compensator is more flexible in comparison to similar single-ply compensators. The maximum operating temperature of the Balance IV is +550 °C, the maximum working pressure 2,5 bar (50 °C).
