Dry disconnect couplings are safety components They facilitate quick coupling and decoupling of filled hose and pipe lines under operating pressure without significant leaks or loss of pumped media.
Dry disconnect couplings are always used in situations where man and/or the environment must be protected against leaks of hazardous media (caustic, toxic, explosive, etc.). Or vice-versa, sensitive media (e.g. foodstuffs as well as pharmaceuticals and fine chemical products) must be protected against contamination by the environment.
Depending on the area of application, entirely different technical designs are required, yet all work on the following basic principle:
The two coupling halves in the separated (decoupled) state are closed by a sealing mechanism so that media cannot escape. When coupling, the two halves are initially impermeably connected with each other before the valves are opened and the flow cross section inside the coupling is open. Vice-versa, before separation, both coupling halves are first blocked again so that the flow channel is closed.
