Hydraulic Counterbalance Valve Comparable Replacement to Sun Hydraulics CBCA-LHN, 3:1 pilot ratio, standard capacity

Q: How big is a drop of hydraulic oil?

There are exactly 250 Sun drops in a cubic inch or 15 in a cc.

Q: 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.

Q: Why can't I block the pilot vent port? That area is positively sealed, isn't it?

Yes it is sealed; however every time the valve is cycled a small amount of oil passes into the spring chamber--about 1 drop for every 4000 cycles. If the vent is blocked, the spring chamber will eventually fill with oil, building pressure until the valve won't open.
