1. A split ring assembly for adjusting the throughput of a fluid of a hydraulic valve, comprising an elastomeric element being adapted to mount a split ring around a hydraulic ram, wherein the split ring is disposed within a groove of a housing, the split ring extending the entirety of a length of the groove in a longitudinal direction, wherein the elastomeric element is arranged around the outward circumference of the split ring and between the split ring and the housing such that there is no gap between any of the split ring, the elastomeric element, and the housing, wherein the throughput of the fluid is adjustable depending on the degree to which the throughput of hydraulic fluid is limited by the split ring.
