VICKERS FR2 10 S 0 /3.00

You bet. This Vickers FR2 flow control valve is rated for pressures up to 350 bar, which is just about 5000 psi, so you should be good to go.

For harvester applications, 38 liters per minute is right in line with what the FR2 10 S 0 /3.00 is built to handle. The valve is pressure-compensated and adjustable, so it holds a consistent flow rate even when system pressure shifts around during operation. Vickers listed harvesters as a direct application for this series, so you're not forcing a fit here. The 350 bar pressure rating gives you plenty of headroom for the demands that kind of equipment puts on a hydraulic circuit.

It’s an adjustable, pressure-compensated flow regulator. That means it’s meant to hold a steadier set flow as system pressure changes, instead of acting like a simple fixed restrictor.
