*See how the most advanced valve on the market raises the bar on efficiency for mobile machinery. 

How we increase productivity in mobile machinery

Customers rely on hydraulic power for lifting, digging, drilling and spraying. Eaton’s CMA advanced mobile valve optimizes every bit of power as it creates smoother, more efficient motion on the job.

This algorithmically driven, CAN-enabled electrohydraulic valve seamlessly communicates to adjust to workloads in seconds, making it the most advanced mobile valve available on the market. The CMA’s boom stability control dramatically reduces boom oscillation to maintain work speeds and keep nearby workers safe. Its hose burst detection prevents hydraulic oil from contaminating the environment if a hose ruptures. And its limp mode operation prevents machinery from shutdown during a malfunction, so workers on the job can finish the day without repair downtime.

Whether pumping concrete, dowsing a fire, harvesting crops, loading logs or hoisting people and materials hundreds of feet in the air, the CMA valve helps your customers safely pump up productivity with precision. 

Reduce boom bounce. Pump up precision and safety.

The longer the boom, the more its tip can oscillate. Expansive concrete pump trucks may need additional workers to hold the tip hose. Pumping speeds might also decline. Both can reduce productivity and put workers at risk.  

Our proprietary boom stability control algorithm reduces oscillation by up to 75% and boom settling time by up to 90%. With its onboard sensing and independent metering capabilities, the valve automatically detects disturbances and stabilizes the boom structure. Everything’s internal; no additional hardware and minimal wiring make integrating with OEM sensors and controllers easy. Customers experience quicker boom deployment, faster point-to-point movement and more precise boom placement—all while protecting those working nearby. 

Protect the environment and project timelines

Oil leaks are a severe hazard, especially in drilling, refuse collection and agriculture. When a hose ruptures, an entire hydraulic reservoir can drain in seconds. The CMA’s hose burst detection feature stops hydraulic oil flow automatically during a rupture—often before the operator notices a problem. Built-in pressure and position sensors monitor flow consumption and close the spools if a large leak is detected in the circuit. This can dramatically reduce the amount of oil spilled, which minimizes the expense and time needed for cleanup. 

Finish the job, even if equipment fails

The CMA valve uses two independent spools to control flow into and out of an actuator. Four sensors monitor position and pressure—two on each side. Flows entering and exiting an actuator create one piece of redundant information between the sensors. The CMA relies on this redundancy to develop algorithms that apply information from the non-faulty side to ensure stable flow control on the faulty side, allowing the valve to continue operation if one of the four sensors fails. These fault-tolerant algorithms prevent automatic shutdown so machines can finish the job before repair is required, minimizing downtime in the field.
