Quick-disconnect couplings

Description
The quick-disconnect coupling is a coupling of sturdy design which locks automatically after uncoupling. The coupling and uncoupling process can be effected when both coupling parts are depressurised. The displacement of the sleeve to the corresponding coupling or uncoupling direction enables an easy one-hand operation.

Coupling “Push”
The knurled sliding sleeve of the coupling will be advanced manually. The coupling has to be advanced against the spring force of both sealing cones onto the nipple against mechanical stop.
When the sleeve is let off in this position the balls snap into the groove of the nipple. The position of the coupling should subsequently be rechecked.

Uncoupling “Pull”
The knurled sliding sleeve of the coupling will be drawn back manually. The balls will be free and  both  coupling  parts  will  disengage  from each other.

Coded couplings
In case of more than one coupling port there is the risk of confusion when coupling. The coded couplings are not only marked by colour but additionally by means of a pin inside of the coupling which only fits into the groove of the corresponding nipple. The risk of confusion is thereby eliminated.

Important notes!
The coupling should only be operated in depressurized  mode. After uncoupling the coupling and the nipple should be fitted with the attached dust cap as shown on the photos.
If the coupling remains coupled, the two dust caps should also be joined together as shown on the photo at the top.
