1SE30 Series Counterbalance Cartridge Valve, 1015-5075 PSI (Factory Setting At 3045.00), Screw with Locknut Adjustment, 5:1 Pilot Ratio

Load runaway is exactly what the 1SE30 series was built to stop. It works as a counterbalance valve, meaning it holds the load in place until pilot pressure from the opposite side of the circuit tells it to release in a controlled way. The 5:1 pilot ratio on this particular unit is the standard selection for applications where the load varies, which fits harvester work pretty well. Factory pressure is set at 3045 PSI out of the box, and it's adjustable anywhere from 1015 to 5075 PSI using the screw and locknut if your system needs something different. It also gives you hose burst protection, so if a line lets go, the load stays put rather than dropping free.

It's designed for applications like harvesters, refuse haulers, and various mobile and industrial setups.
