The proportional valve EATON CMA represents a revolution in motion control for mobile applications. Its independent metering architecture, with a separate 3-way spool for each A and B port, allows individual control of each of the cylinder chambers, enabling different operating modes to be selected, depending on load characteristics, integration needs with other valves or energy efficiency strategies.
For each section, it includes pressure sensors at the P, T, A and B ports, temperature sensor at the T port and position sensor for each spool. All this information is used in the internal control system for maximum performance and can also be shared with the machine control system, avoiding the need for additional sensors. All of this is integrated into a single CAN communication cable for all sections, simplifying wiring and reducing costs.
