Why Use Oil Sampling Valves

For years companies have used oil analysis to determine the health and condition of their equipment. Most recognize the value of using oil analysis to avoid unplanned equipment downtime and for planning oil changes. However, most companies are not getting the most out of their oil analysis program because they do not understand the importance of proper oil sampling.

Oil samples are the important first step in any oil analysis program. Without one, the lab would have nothing to analyze. The aim of any predictive oil analysis program is to trend any gradual changes in fluid properties, contaminants and wear debris so that corrective action can be started in a controlled, planned manner. The results from your sample will determine if corrective actions need to be taken. An improper sample can skew these results, producing either costly false negatives or false positives. Ultimately those improper samples can cause an oil analysis program to be abandoned.

A proper sample represents the true condition of the equipment. It's taken while the equipment is running and it is taken from the same spot every time.

Sampling valves are the best method for obtaining proper, reliable oil samples. They make it possible to take oil samples safely, while the equipment is running, from the same spot, every time. This means that oil samples can be taken at any time since shutdowns are no longer necessary. Sampling, while the equipment is running, ensures that the sample is a direct representation of the equipment’s condition. Additionally, the oil sample is coming from the same spot in the active zone every time, away from the sediment and filters. Meaning that the sample pulled will contain hot, information-rich oil that can be trended against previous samples to show the condition of your equipment.
