[daip] VLA actuators

[John Sallas]

I visited the VLA in New Mexico last week while on vacation and was wondering if you used any hydraulic actuators in steering the antennas?  In particular do you use any proportional hydraulic four-way servovalves?  

If so I was wondering what model(s) you are currently using, as I am working on a small hydraulic valve with ATLAS FLUID CONTROLS in Houston (a manufacturer of serovalves widely used in geophysical exploration) .

Thanks,
