Depending on your requirements, BGB can support you in the design of multi- passage swivel joints, combined solutions and facilitation of various fluids. In highly corrosive environments (such as marine) or where there is exposure to external agents, BGB can support you in the most appropriate material selection to ensure solution life expectancy is achieved and the cleanliness of your medium is protected.
For higher pressure applications with fewer channels, BGB is able to test up to 300bar to ensure the leakage rates are within specification.
BGB systems can also include optional features like: Limit Switches, Encoders, Condition Monitoring, Lightning Protection, Fibre Optic Joints and slip ring assemblies
