CMA Advanced Mobile Valve with Independent Metering - CMA 90, CMA 200

CMA Advanced Mobile Valve Introducing an electrohydraulic mobile valve that’s challenging the limits of what’s possible. With a sophisticated technology platform that dramatically streamlines and simplifies everything from design and setup to operation and optimization, the Eaton CMA Advanced Mobile Valve with Independent Metering is redefining what mobile machines can do. And the improvements they enable end users to achieve. Featuring on-board electronics and sophisticated software algorithms, CMA provides more flexible configuration, more immediate communication and more precise control than ever before. You can also count on Eaton’s global network of certified distributor partners to help you with everything from specifying and prototyping to assembly and commissioning. 

Common applications include concrete pump trucks, refuse trucks, telehandlers, all-terrain cranes, utility trucks, grapples, aerial lifts, drill rigs, excavators, roof bolters, snow groomers, paving machines, reach stackers and more.



Addresses these engineering challenges:


  • Hardware changes to conventional valve spools and housing makes machine calibration costly and time consuming
  • Without load sense capability, pump instability occurs due to the interaction of machine and valve dynamics
  • Prevalence of pump saturation with conventional hydraulic valves
  • Before now, machine operators and engineers have lacked visibility to machine performance data, making it difficult to detect and prevent potential problems


Product Features


  • Pre-built software libraries – Using Eaton’s Pro-FX® Technology Platform, common application functions can be enabled right on the valve, reducing development time
     
  • Electronic tuning – Engineers can test and optimize performance parameters electronically instead of manually in seconds or minutes
     
  • Easy controls integration – CMA easily integrates with Pro-FX products such as 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 
     
  • Independent metering – Each spool controls its own work port, ensuring consistent speed and control in over-center conditions
     
  • Advanced control algorithms – CMA automatically optimizes for conditions such as oscillation and vibration, improving control and reducing risk
     
  • Real-time diagnostics – On-board sensors monitor pressure, temperature, position and flow, helping operators detect and troubleshoot issues more quickly
     
  • Limp mode – if a sensor goes down in the field, the operator can work at a slower or reduced rate until the machine can be serviced, minimizing downtime

Articles & White Papers

How Limp Mode Allows you To Finish the Job
By Michael Rannow
The Eaton CMA90 and CMA200 valve are intelligent independent metering valves with twin-spools.  This article explores the limp mode feature – if a sensor fails, the user can work at a slower or reduced rate until the machine can be serviced, minimizing downtime.

Banishing Boom Bounce with the CMA Valve

By Stephen Smith
This article explores the boom bounce feature – stabilize the cylinder position – and thus the entire boom structure – Eaton developed a system that includes a CMA mobile valve in place of the traditional mobile valve, as well as pressure sensors, counterbalance valves and an HFX controller, utilizing the Pro-FX Technology platform.

Fail Operational Controls for an Independent Metering Valve
By Michael Rannow
Technical white paper first published within the 10th international fluid power conference 2016 in Dresden, Germany. By maintaining a constant pressure, the flow in and out of the actuator are balanced.  Experimental results on the boom of a backhoe demonstrate the operation of the fault tolerant control strategy.

Forestry Case Study: Smarter machines for improved control, efficiency and safety
By Chris Schottler
The forestry industry continues to be radically altered by technology as it seeks increased productivity and greater efficiencies. Smarter machines begin to answer questions about productivity, efficiency and safety.  See how Eaton’s CMA valve is revolutionizing foresting machinery.

Prinoth Case Study: Smarter machines provide quicker response times for challenging conditions and simplified manufacturing
By Daniel Galler
Prinoth Snow Groomers operate in punishing conditions: wet, cold, at high altitude and often on extreme slopes. While engine management and operator controls have improved with technology, hydraulic operations had lagged behind. The Eaton CMA valve allowed faster response times for operators as well as significantly reducing manufacturing complexity.

Simplifying Setup and Controls with Smarter Components
By Jason Kraft
Many traditional hydraulics customers worry that switching to electrohydraulic solutions will require a great deal of expertise for initial set up, operation and troubleshooting. But, as electronics advance, it becomes clear that they can help solve the very issues that have slowed adoption of this technology.
