Quick couplings screw type preopening System


These couplings with sphere shutters have been created to satisfy some requirements of functionality and safety that other kinds of couplings don’t have. Quick screwing and releasing through a particular trapezoidal thread also in the presence of a residual pressure in the circuit. Total functionality through a preopening spacer even if the coupling isn’t completely screwed.
