New Mobile Valve Section Increases Design Flexibility

By adding the new CMT mobile valve section, Eaton improves design flexibility while reducing the size of the valve bench. CMT can control two services and it is software configurable. CMT expands the CMA advanced mobile valve family.

The power management company Eaton introduced the CMT mobile valve section, a streamlined new section option for the CMA advanced mobile valve. With the capability to control two bidirectional services from one section, the CMT valve section increases design flexibility and reduces CMA valve bank size, weight and overall system cost. Like the existing CMA mobile valve section, the new CMT section is software-configurable and features CAN communication, on-board sensors, digital flow-sharing and electronic load-sensing to provide precise flow control and high responsiveness. While the CMA section features independent metering, the CMT section utilises the twin-spool architecture to control two services instead of one. This can reduce the total number of sections needed in a valve bank by as much as 50%, minimising valve-bank size and weight.

The two types of section can be combined

CMT mobile valve sections are stackable with CMA sections, which increases the design flexibility of the CMA advanced mobile valve. Original equipment manufacturers (OEMs) can optimise the valve for all vehicle requirements by specifying sophisticated CMA sections for services that demand superior precision and control and streamlined CMT sections for standard machine functions. The availability of two stackable section options simplifies the use of the CMA valve on high-end and mid-range machines without parts proliferation, due to shared components and procedures. The CMA advanced mobile valve significantly improves machine performance and operator productivity. Featuring on-board electronics and sophisticated software algorithms, the CMA valve can optimise for conditions such as oscillation and vibration to deliver better stability, controllability and fuel efficiency. The software-driven set-up eliminates hardware replacements and enables performance optimisation in minutes instead of months, speeding time to market.
