1CEV30 Series Counterbalance Cartridge Valve, 1450-4000 PSI (Factory Setting At 3500.00), Screw Adjustment, 5:1 Pilot Ratio

This counterbalance valve is suitable for mobile applications like refuse haulers, offering control for hydraulic actuators. Just make sure your system meets the recommended filtration level of ISO 18/13 or better to keep it running smoothly.

For a harvester where the load shifts around a lot or where the machine structure has some flex to it, the 5:1 ratio is actually the better fit. The 7:1 is built more for situations where the load stays pretty steady throughout the cycle. If you're dealing with variable loads or any structural flex that could feed instability back into the circuit, the 5:1 gives you better control and is less likely to hunt or chatter during operation.
