Problem: Failure to lubricate valves is one of the principal causes of valve failure, according to CPV, a manufacturer of leakproof valves and fittings, and can lead to costly repairs and loss of productivity. While it is easy to see why complex, multi-part components require lubrication, valves are a different story. Usually, valve movement is limited to opening and closing, and the need for lubrication often is overlooked.

Solution: Valve lubrication can be as simple as opening the valve and smearing a small amount of lubricant on the stem. When a regular lubrication schedule is adhered to, maintenance takes less time, the number of emergencies decreases and the piping system lasts longer.

It’s also important to specify a lubricant that is compatible with the system in which the valve will be used. Seals and stem threads can be properly lubricated before the valves are shipped, if you request it.

Hydraulic piping systems generally are not a concern because they usually have sufficient lubricity. But lubrication can be critical in gas piping systems which function under high pressures.
