CATALOGUE » Hydronaut products » Press brake control units

The press brake hydraulic control units are suitable for machines with the parallelism assured by torsion bar.

 

The working phases are common for all the models and are the following:

·          Fast down: each model is provided with suction valve of adequate capacity

·          Pressing: the pump is working; when the pressure set point is reached, a sensor send a signal to the control system decompression starts

·          Decompression: after the signal, the control system can set the directional control valve in neutral position and the decompression takes place.

·          Inversion: when the decompression is completed, the control system switch the directional control valve and the ram goes up fast thanks to the rapid discharge valves.

 

Four models of control unit (in ascending order of suction capability) are available:

·          CP473E: with built-in suction valve (for fast down operations) and built-in rapid discharge valves (for fast return) incorporated; suitable for machines up to 60 ton force;

·          CP473D: with double built-in suction valve (for fast down operations) and built-in rapid discharge valves (for fast return) incorporated; for machines up to 120 ton force

·          CP310-6: with external inlet valves, for flow rate up to 35 L/min

·          CP310-10: with external inlet valves, for flow rate up to 70 L/min
