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. On Alibaba.com.The frequency at which a solenoid valve should be serviced is very much design- and application-dependant. However, high-end designs exist where the interaction of components is so critical that servicing the valve in the field is not recommended for fear that the original function may not be attained. As with other products, there are varying levels of durability built into different solenoid valves.Certain types are so simple in design and construction that low replacement cost makes this the most simple and cost-effective choice. 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.Repair or replace In order to make the repair vs replace decision, consider again the valve itself as well as the overall application. Valves controlling water can experience mineral buildup, especially when water sits idle in the valve for extended periods of time.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. 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. Before repairing a valve, always disconnect the power source and depressurize the system. Here are the steps of the maintenance regimen: Of course, be sure that the replacement kit is appropriate for the particular valve. Never power up an ac coil without ensuring that the coil is properly installed on the valve’s sleeve or stem. Connections to the coil should be checked for damage or corrosion. In wet or humid environments, these can lead to moisture penetrating the coil, resulting in valve failure. Inspect the coil for cracks in the encapsulation. These include the plunger with a seal, the plunger return spring, an O-ring, the sleeve, and the operator body. Care should be taken to never remove the sleeve by clamping onto the sleeve tube, as this may cause the tube to dent or bend.Removal of the sleeve from the valve body will expose the internal components of the valve operator. The sleeve will have a feature to accept a sleeve removal tool, usually a wrench. When the coil is removed, the resulting unit is the pressure vessel. Then reinstall the newly assembled valve back into the application. Once all necessary parts are replaced and the valve cleaned of buildup and grime, reassemble the pressure vessel according to the manufacturer’s directions and reattach the coil. As a result, the top of the plunger and the inside of the sleeve may show wear as well.For more complex solenoid valve types using diaphragms, pistons, spools, and levers, specific manufacturers’ instructions must always be followed. When the plunger lifts, it normally makes contact with the sides and stop of the sleeve. The body orifice may be nicked or the crest may be worn. The spring should be inspected for worn or broken coils.

It does not energize when power is applied. There could be any number of malfunctions with the valve: Disassemble valve clean out extraneous matter. Make sure that pressure complies with nameplate rating.Valve is sluggish or inoperative—electrical supply and pressure check out.1. Check coil with ohmmeter for shorted or opened coil.3. Voltage must agree with nameplate rating.2. Check electrical supply with voltmeter.
