1. Flashing an ECU on a Machine That’s Running . . .

Switching from manually operated valves to electro-hydraulics is a big step. You are, in a sense, pulling the operator one step further away from the machine. For some people, this is great and they love a color display that allows them to endlessly tweak a hydraulic system without getting soaked with oil. Others enjoy the feel and perceived reliability of a manually configured electronic device system, and find a more traditional technology, such as an analog valve driver that is easily tuned with a screwdriver and trim pots more appealing.
1. Applying dither to a valve reduces actuator friction and reduces hysteresis. A good rule of thumb is to use 70 -250 Hz dither frequency on all SP, ZL, and PV valves (flow and directional control valves), and 200-300 Hz dither frequency on TS Valves (proportional pressure control valves). Otherwise, at lower frequencies the actuator will follow the dither signal and the valve output will appear unstable.
Holy turbo chargers! When it’s a boost valve!
What if I told you I could design a hydraulic system that functions the same or better than your current system, but with less cost, less space requirement, fewer leak points, better appearance and less assembly and installation time? First of all, would you even believe me? Secondly, why aren’t you doing it already?
The idea to develop Multifunction Valves came from our engineers noticing that particular combinations of valves were used over and over again in standard hydraulic circuits. For example, a 2-way, 2-position SP proportional valve is typically paired with a pressure compensator to provide pressure compensated flow control. This particular example drove the development of the PV Proportional Flow Control family of valves, which include the flow control and pressure compensator inside the same cartridge. There are many other multi-function options, including the SPCL, SVCL, SVRV, EPFR, FRRV, and others).
As Lisa pointed out in a previous post, we skipped the gimmicks this year and went back to the basics, our broad product offering. That appears to have been the right decision because the show was a great success for HydraForce. The number of visitors to our boothand their optimism about the future were refreshing. We were mentioned as a ‘company to watch’ in several pre-show news posts, our new products generated a lot of interest and we received many compliments on the design of our booth, which seemed to work very well for our purposes.
