Frequently Asked Questions
Should I replace the counterbalance valve if my cylinder is drifting or moving?
While cylinder drifting is often attributed to a leaking or damaged counterbalance valve, it can also be caused by cylinder seal leakage or changes in oil temperature. If you believe the seat of the counterbalance valve has been damaged, which can be caused by shock or contamination, it is advisable to replace the valve with a new factory set valve. Always follow the manufacturer's recommendations for servicing of hydraulically actuated machinery, and insure all loads are mechanically supported and cartridges are not under pressure when removed.
