KFDG4V-3 Series Subplate/Manifold Mount NFPA Size D03 Proportional Valve With Feedback, 4-Way, 3-Position, Spring Centered, Closed Center, Meter In & Meter Out, 24VDC Amplifier Supplied DIN 43650 Coil. 1500 PSI Port T, No Manual Override

Maintaining the right fluid cleanliness is important; for pressures up to 3000 PSI, aim for an ISO 4406 Cleanliness Level of 18/16/13. If you're running pressures above 3000 PSI, bump that up to Level 17/15/12.

Right in that middle ground is exactly where this valve lives. It uses an LVDT feedback signal that keeps the spool position accurate without pushing you into full servo valve territory. You get proportional control of velocity, direction, and acceleration based on current input to the solenoid, which makes it well suited for press work where repeatability matters but you don't need servo-level precision. The closed center spool holds position when no signal is applied, and the spring centering brings it back to neutral on power loss. For press applications, that setup tends to be a solid fit.
