If there is no coupling stroke required or possible, this coupling system can be coupled separately by a control pressure. The gap between the coupling mechanism and coupling nipple can be 0.6 - 1.0 mm.
The coupling surfaces of AKN and AKM are frontally flat so that the user can positioning them in any axial and / or radial positions for coupling in accordance with the positioning tolerance. An integrated control piston A initiates the clamping stroke. It is possible to control individual couplings specifically. The control pressure A is to be supplied with the same pressure as the media pressure P. When the control port A is not pressurized, the AKM is set into the basic position. The maximum operating pressure is 350/300 bar. The AKM can be operated single-acting or doubleacting. If the AKM should operate single-acting, the port B must be used for housing ventilation. In order to increase the operational safety, the double-acting operation method is preferable.
