• Turn adjustment clockwise to increase setting
• Backpressure at port 2 adds to the effective relief setting at a ratio of 1 plus the pilot
ratio times the backpressure.
• Set your counterbalance valve at least 1.3 times the maximum load induced pressure.
• This valve is not provided with positive seals on the pilot section
• Declared reseat value is obtained with valve set @ maximum setting
