Parker K220LS EcoFormance
Improving Control, Productivity, and Fuel Economy with new EQA Technology.
Parker’s EQA (Electric Flow Amplifier) EcoFormance technology represents one of the next significant advancements in load sensing valves. By automatically adapting the meter-out pressure to the load conditions, machine control is greatly improved by EQA technology.
This is most notably useful for functions with slew or jib movements, or digger arms with over-center movement. Used in hydraulic systems found in mining, forest, and construction machines, this technology offers OEMs a lower risk and the gains in doing so are well defined: in tested applications, a 15 percent productivity increase and 22 percent fuel savings results.
A load sensing valve with EQA technology also allows instant and seamless switching between regenerative mode and double acting mode, as well as between gravity lowering and power down. The added speed and precision improves productivity, enabling more work to be done in a given time.
Parker’s patented EQA EcoFormance technology offers unique and useful features to achieve precise control, improved productivity and energy savings. Parker Eco-Formance K220LS load-sensing valve.
Thanks to the new EQA technology, which automatically adapts the meter-out pressure to the load conditions, machine control is greatly improved. This is especially useful for functions with slew or jib movements, or for digger arms with over-center movement. Greatly improved control – the new, easy Parker way! Unique Parker EQA technology increases productivity and fuel economy
The K220LS EcoFormance allows instant and seamless switching between regenerative mode and double acting mode as well as between gravity lowering and power down. The added speed and precision means more work can be done in a given time.
Minimized meter-out losses reduce fuel consumption. The increased efficiency also means more available power for the work cycle.
EcoFormance work sections can be combined with other K220 LS sections anywhere in a valve stack. Since metering control is done the traditional pre-compensated way, the software only needs to control the timing and the variable meter-out pressure. This can easily be implemented in any OEM ECU-controller. The EcoFormance valves will be available with a plug-and-play.
