New hydraulic valves increase design flexibility

Eaton has announced the introduction of its 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 – claimed to be an industry first – the CMT valve section increases design flexibility and reduces CMA valve bank size, weight and overall system cost says the company.

As with the existing CMA mobile valve section, the new CMT version 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 new CMT section utilises twin-spool architecture to control two services instead of one. This, says Eaton, can reduce the total number of sections needed in a valve bank by as much as 50 per cent, thus minimising valve-bank size and weight.

CMT mobile valve sections are stackable with CMA sections, increasing the design flexibility of the CMA advanced mobile valve. OEM can optimise the valve for vehicle requirements by specifying sophisticated CMA sections for services that demand enhanced precision and control, and streamlined CMT sections for standard machine functions. The availability of two stackable section options simplifies the use of the CMA valves on high-end and mid-range machines without parts proliferation, due to shared components and procedures.

According to Eaton, 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.
