WORKING POSITION:

Counterbalance valves should be set at least 1.3 times the maximum load induced pressure.

Backpressure at port 2 adds to the effective relief setting at a ratio of 1 plus the pilot ratio times the backpressure.

Reseat exceeds 85% of set pressure when the valve is standard set. Setting lower than the standard set pressure may result in lower reseat precentages.
