![]() In these situations, building a maintenance regime into the valve’s use can extend life as well as maintain the consistency of the overall application’s functionality. If one considers a solenoid valve’s small clearances between moving parts and small orifices through which media travel, it stands to reason that unfiltered, corrosive, or viscous (adhering to the inner components) media can substantially increase the likelihood of premature failure. Valves controlling water can experience mineral buildup, especially when water sits idle in the valve for extended periods of time. The lack of lubrication and the pounding of the internal parts can cause valves to deform and deteriorate. Some of the most damaging applications are those that involve dry air and rapid cycling. However, media that are lubricated or provide lubricity can offer component life up to millions of cycles.įor standard valves, controlling media as common as air and water can be a challenge. In this case, it would not be unusual to replace components at 100,000 cycles or less. For example, without lubrication, components wear quickly. Certain applications are particularly damaging to the valve’s internal and external components and will require more frequent attention. The frequency at which a solenoid valve should be serviced is very much design- and application-dependant. ![]() A proactive approach can result in the best possible performance of the valve and the overall system, as well as extended product life. Generally speaking, if the machinery is being taken apart for other service, that may be the best time to complete the valve maintenance procedure. What is the cost for service in terms of time and manpower?.What is the financial cost of a valve failure in terms of productivity and scrapped work?.
