Pressure Setting (continued) Recommended setting is 1.3 times the maximum load induced pressure (use 1.5 times for settings below 2000 psi). To increase the pressure setting, turn the adjustment screw counterclockwise. Counterbalance valves should always be pressure set prior to their installation into the system, for more than just safety reasons. Most importantly, they are very difficult to accurately set once installed on a machine. On rare occasions, it may be necessary to adjust the valve after installation. Following is a suggested setting method that can be used in an emergency. Keep in mind it is strongly recommended that counterbalance cartridges always be factory set by Sun.
