Modern hydraulic system are making in increasing use of sensitive control valves. Failure of control valve will cause very expensive loss of production many times more than the cost of prevention. LubeCheck™-hydraulic oil analysis is an easy way that can be utilize as preventive and predictive program. Information gained from LubeCheck™ can help identify early potential problems, avoid equipment breakdown and loss of production.
