1CEV90 Series Counterbalance Cartridge Valve, 1450 - 5076 PSI (Factory Setting At 2900.00), Screw adjustment, 8:1 Pilot Ratio

For a unidirectional load like a crane, a single overcenter valve is exactly what you want. Dual overcenter valves are built for situations where the load swings both ways, like motor applications or cylinders going over center. Since your load stays in one direction, this valve fits that use case. The 8:1 pilot ratio on this one is also worth noting. That ratio works best when your load stays relatively constant, which is typical for crane lifting. If your load varies a lot or your machine structure tends to cause instability, the 4:1 pilot ratio version would be the better pick.

Single overcenter valves like this one are often used when the load is unidirectional, like you'd find on an aerial platform or a crane. Just be sure your pressures are within the 1450 - 5076 PSI range.
