Redefine what your mobile machine can do

The CMA valve’s impressive list of intelligent features enables a whole new level of productivity, so that you can get the job done quickly, safely and effectively. 

  • Advanced control algorithms: The valve can optimise for conditions such as oscillation and vibration, improving control and reducing safety risks. See it in action. 
  • Hose-burst detection: The valve monitors flow to and from the service and closes the spool if a leak is detected, preventing costly spills. See it in action.
  • Limp mode: If a sensor goes down in the field, you can work at a slower or reduced rate until the machine can be serviced, minimising downtime. Learn more.
  • Switchable control modes: Switch between velocity and force control on the fly, which allows for new machine control workflows.
  • Real-time diagnostics: On-board sensors monitor pressure, temperature, position and flow to help you detect and troubleshoot issues quicker.

Improve machine performance and productivity

With its unique architecture, Eaton’s CMA valve provides better stability, controllability and fuel efficiency.

  • Independent metering: Each spool controls its own work port, ensuring consistent speed and better control in over-centre conditions (CMA sections only).
  • Software-configurable flow sharing: Easily modify flow-share priorities in software rather than swapping out hardware, and move beyond pre- and post-compensation to more custom methodologies.
  • Internal electronic load-sensing: Eliminates the need for a load-sense line and improves controllability and fuel efficiency when paired with a compatible pump.
  • Distributed architecture: CAN communication between valves allows them to be located closer to the controlled service, which reduces electrical wiring.

Dramatically simplify machine design and set-up 

With on-board electronics and sophisticated software, the CMA valve streamlines the design process and reduces set-up from months to minutes, helping manufacturers lower costs and speed time to market. 

  • Pre-built software libraries: Using Eaton’s Pro-FX Technology Platform, you can enable common application functions on the valve, reducing development time.
  • Electronic tuning: Test and optimise performance parameters in minutes instead of months.
  • Easy controls integration: The CMA valve easily integrates with other Pro-FX Ready products such as Eaton’s VFX displays and HFX controllers for a best-in-class solution.
  • Integrated sensors and software logic: On-board components eliminate the need to purchase and integrate external sensors and switches.
  • Industry-standard protocols: The CMA valve supports both the J1939 and CANopen communication protocols.
