Monitored hydraulic valves

Monitored hydraulic valves

Monitored hydraulic valves

(OP)
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.

RE: Monitored hydraulic valves

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?

RE: Monitored hydraulic valves

If you visit website www.fluidsentry.com you should find what you are seeking.  Fluidsentry specialise in pneumatic & hydraulic monitored safety valves, using positive opening high precision limit switches for monitoring spool position.
