Looking for spool position monitored valves

[real]

Hi,

I'm trying to find a hydraulic (and pneumatic) control valve in witch some sort of position sensing (electrical)would indicate the spool position.

I was told that Parker had this kind of valve but was unable to find it.

Thanks,
Real

Parker and all other hydraulic valve manufacturers have these valves in several sizes. Only about four have them for pneumatics. Festo is a good source for pneumatic proportional valves

Go to

and look in the Designers Guide for manufacturers of hydraulic and pneumatic proportional valves.
