The valves may have high ratings as well as hydraulic hoses that exceed 3000 psi but the hydraulic cylinders are rated for only 2500 or 3000 psi. Hydraulic cylinders are made that exceed 3000 psi ratings but the cost 2 to 3 times as much. The 2-stage pumps used on splitters are also rated 3000 psi max.
If a manufacturer sets max. pressure above the rating of the weakest component, lawyers see dollar $$$$$$$.
It's been implied here that you know what the valves, pumps, and other components are rated for. I'm here to tell you as one of the engineers responsible for the design of the SpeeCo (and Huskee) splitters that there are some false statements in your post.
The relief pressure on the valves are set at 3100-3200 or 3400-3500 PSI (depending on model). The hoses, tubes, and cylinders are rated appropriately. The pumps that we use are rated for use at 3500 PSI. We have tested these components to failure, and as a company and I personally will attest to the fact that these components are safe to use as designed and assembled.
Just thought I would throw this in for those that care. Brave is a division of Iron & Oak and at least as of last year, the product was USA made. Husky = Speeco = comes in a sea container from China.........
Huskee does equal SpeeCo. SpeeCo means engineered in Golden Colorado, components built in China, Korea, the United States, and any other place the economics dictate. Some of the subcomponents (pumps from Haldex and MTE, valves from Energy, engines) are purchased to our specifications. Parts are brought into out facility in Golden Colorado, QC inspected, and assembled into crates to be sent out.
I am not sure if Iron and Oak is fully built in the USA, I do know they make good product. One other major log splitter seller who's new line of splitters is mentioned here often are made and assembled complete overseas.
Sorry for the long post, but I wanted to clear up some misconceptions that have been floated around.
