Volume Compensator Bellows
Our line of electroformed volume compensator bellows assemblies can prevent damage to closed pressure vessels and piping systems due to fluid thermal growth. Volume compensation can be the key factor in avoiding pressure build-up, leakage and catastrophic failure in these systems.
Bellows volume compensators can also be used to “sense” significant drops in the pressure of a charged system or device. When there are volumetric changes in the process fluid, the bellows will compensate in response.
Custom Manufacturing
Custom Bellows Volume Compensators
We custom manufacture bellows volume compensators in a variety of styles, including vented and closed, to fit your application's unique needs. Our team can provide design support and manufacturing expertise that will ensure you get the best performance at the most cost-effective price.
