Sorry I'm asking a question as my first post, but I was wondering if you guys could help me with this problem I'm having with my project. I'm trying to modulate hydraulics in a 5mm line with a max rating of 100psi. I need it to have rapid oscillations. Electronically, it cannot exceed 12Vdc. What do you think is the best way to do so? Thanks in advance.
The first thing to ask is, what is the frequency of the oscillations?
You can do this with an electro-magnetic coil feeding am lower pressure hydraulic valve. This can then be used to drive a higher pressure valve.
I have worked with a dual valve oil hydrualic system for powering JCB diggers etc.
