Monitored hydraulic valves

[wintek]

This is not really a technical question but does anybody know who makes hydraulic directional control valves with elecrical feedback of the spool position? Not servo valves but discreet Open/close valves. I believe Parker has them but cannot find a P/N.

Eaton electrical makes these. I believe they call them proportional valves. They have many options for feedback, 4-20mA, CAN, etc.
If your really only talking open or close valve then I assume you just want some reassurance that the valve is indeed open or closed?
