These values I use for my calculations when I need to compare flow velocity with recommended min and max values. I took these data from different sources: recommendations in technical manuals of Parker, Gates, Eaton and other hose and tubes suppliers.
These are average values from my collection of all supplier recommendations.

For my work I use AutoCAD LT or ePlan Fluid to draw hydraulic, pneumatic, lube and P&ID schematics. Companies where I worked and where I have the work now, provide this software because the price of them is unbelievably high for the regular individual.
One day, after reading of this article I decided to try to find something absolutely FREE for Fluid Power schematic design.
All software what I found, I divided into three categories:

There are two types of valve circuits can be used to control your system: “Open center circuit” and “Close center circuit”.
New QuickDesign with SmartConnect from SUN
SUN announced about new SmartConnect schematic tool for manifold design.
The direct link where you can read more about this online application is here . In addition SUN offers the free webinars how to use it.
This is a very interesting feature which really simplifies the preparing work of manifold design. The online application is free and required a free registration only. Before this time it was a pretty complicate algorithm to indicate connections between cartridges’ ports. Now you just draw a hydraulic schematic (easy drag and drop SUN components) and with next step you get ready to use manifold design drawing set.
I used SUN manifold design before and tried to use it now with SmartConnect – I see the difference, and it is really improving and great feature.
I think the next step from SUN to be components’ placement optimization. I really like the idea of free online manifold design, but on the other hand, I found the complicated design from SUN has not optimal components placement and always manual correction required. And the problem with it – it hard to do in CREO because at the end we get STEP file which impossible (or very hard and uncomfortable) to modify. But anyways, this online application can give you some idea how to place components in the space and this is a good basis for your own manifold design. This is why I at least recommend to pay attention to QuickDesign with SmartConnect tool.
