EATON CMA Mobile Valve

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

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
