Product Usage Instructions

1. Locate the counterbalance valve with the ordering code CB-2A-X-Y-Z.
2. To reduce the setting and release the load, use a 4.0 Hex. Turn the screw and rotate it clockwise.
3. To ensure proper torque, use a 14.0 Hex. Torque and tighten it between 6 – 7 Nm.
4. The control option allows for maximum extension from the locating shoulder. (Z=L Control shown)
5. Refer to the illustrations for detailed information on the pilot, load, and valve.
6. The maximum setting pressure should be 1.3 times the maximum load-induced pressure. For example, if the max setting pressure is 350 bar, the load pressure should be lower than 270 bar.
7. The pressure setting can be adjusted within the ranges mentioned under OPTIONS.
8. The pilot ratio varies depending on the configuration:
   • X: 10: 1
   • Y: 4.5: 1
   • Z (with the sealed pilot): 2.3: 1
9. There are adjustment ranges available for specific purposes:
   • J: 140 – 350 bar (210 bar Standard Setting)
   • K: 70 – 175 bar (140 bar Standard Setting)
   • C: 140 – 350 bar (210 bar Standard Setting)
   • D: 70 – 175 bar (140 bar Standard Setting)
10. Additional options include:
    • Leakproof hex. socket screw
    • Leakproof hex. socket screw with stainless steel external metal components
    • Plastic tamper-resistant cover
11. Please note that the illustrations and details provided are for reference only and are subject to change.
