Original Hansen Tube-Hose Quick-Disconnect Coupling of HK Series

Double shut-off versions

(single or non shut-off versions also available)

Quick-disconnect couplings of series HK are of double shut-off, single shut-off or straight-through design. The double shut-off type is recommendable for hazardous media such as acids, solutions, hot water or steam. In single shut-off couplings and depending on the individual application either the socket or the plug accommodates the integrated shut-off valve.
When the connection is made the valves will not be caused to open before the coupling has been positively sealed off to the outside. On the other hand, the connection will not be separated before the valves have been closed.
This quick-disconnect coupling features non-spill operating characteristics.

Function

Principle: First sealing, then clearing the passage!
When the coupling is connected the valves of the socket and the plug are pushed open. Before the valves clear the passage they seal off the interior against ambient influences.
Due to the robust design air inclusions during coupling and residual leakage during separation are minimized.
