VICKERS-RV1-10-S-0-9/7

For those kinds of machines, the RV1-10 series is exactly what's being targeted. Harvesters and refuse haulers are both listed application types for this valve, so it's not a stretch to put it there. The 30 L/min flow rate on this specific model is the rated capacity for this configuration, and the 350 bar pressure ceiling gives you solid headroom for demanding mobile circuits. The poppet-style construction is also a practical choice for equipment that sees regular, repeated pressure cycles since it tends to hold its set point consistently over time.

The RV1-10 series is designed to handle a maximum system pressure of 350 bar, which converts to about 5,000 psi, so 4500 psi should be well within its operating range.
