Electrohydraulic Releases ZE-120/50
Application
Operation of the release consists in advance of the piston rod with appropriate force and to specific stroke.
The release finds application mainly in brakes for releasing (opening) shoe and also disk brakes. With built-in spring, it not only releases the brake but also generates braking torque. The release can be used for all applications requiring to-and-fro movement, e.g. to actuate gates and valves, to open and close flaps and doors, to raise and lower barriers and also to move levers and pull-rods.
Releases are driven by inductive three-phase cage motors, installed inside the release housing, which can be rated up to 500 V AC and 50 Hz.
The release can be used both for continuous operation S1 as well as for periodically interrupted operation S3 with relative loading time up to 100% and number of actuations up to 2000 c / h.
