The caution here is to verify that the valve seat is not nicked or worn, which may result in seat leakage even with new seals. On the other hand, if the valveвЂ™s connections have sweat fittings or its location makes its removal difficult or dangerous, it may be wiser to leave the valve body in place and rebuild its components regularly. If the remaining parts show wear or are damaged, it is time for replacement. Maintenance generally implies solely the replacement of the rubber parts and springs. Likewise, the replacement cost may be significantly greater in comparison to a maintenance scenario, especially in cases with custom designs or exotic materials. 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.Д¬ertain types are so simple in design and construction that low replacement cost makes this the most simple and cost-effective choice. Repair or replace In order to make the repair vs replace decision, consider again the valve itself as well as the overall application. In these situations, building a maintenance regime into the valveвЂ™s use can extend life as well as maintain the consistency of the overall applicationвЂ™s functionality. If one considers a solenoid valveвЂ™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.ДЇor 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 valveвЂ™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?.

Shot a half dozen pellets and after a half hour it seems to still be firing just as quickly. Loaded, cocked and fired for the first time in a long while.

How's it work? Well, putting in a new co2 and a good smack, yielded nothing.

All parts installed and back together in about a half hour. Took a dozen tries and it was dropped a few times too, but perseverance paid off. No brain surgery, just a small stiff part that needs to stretch.

Install was straight forward, but tricky getting the small o-rings on. I've been trying to get the piston part that this kit contains for a long time. In the mean time I heard about you guys and went to this site and low n behold wouldnt you know it, a new and improved poppet is included in the kit!!! Well since this is an initial post I will follow up in about a week and give you guys my final review! BTW, I,m really excited about this rebuild and cant wait to fire it again after 40+ yrs!!!ДЈ of 3 people found the following review helpful: The only problem was the urethane seal on the poppet valve was not included. Peter Seely from STANLEY, VA United StatesДЇirst of all I have had my 78g since 1974 when it was given to me on my 13th bday! I am now 60yrs old! I recently disassembled it in order to reseal it.
