Scope

This document specifies the dimensions and requirements for hydraulic flat quick-change couplings with a maximum working pressure of 10 MPa to 31.5 MPa (corresponding to different specifications).
This document applies to hydraulic flat quick-change couplings that are not connected or disconnected under pressure.
Note: When the quick-change coupling is disconnected in the connected state, the separated coupling ends automatically seal the upstream and downstream fluids.
