Technical Details
Setting (bar)
• 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 provided with positive seals between all ports
• Declared reseat value is obtained with valve set @ maximum setting
