While Koganei pneumatic valves are among the highest quality and most dependable valves available to the industry, there are times when malfunctions are inevitable. Most of the time, however, this is not due to the valves themselves, but have more to do with the way in which they were installed, operator error, inadequate maintenance, and a host of other possible reasons. Your engineers might, for instance, have incorrectly installed the Crouzet optical sensors that were supposed to automate your production line, thus forcing you to shut down the entire system and troubleshoot. |
Leaks are among the most common problems with pneumatic systems, as compressed air cannot be seen by the naked eye and at the same time demands a completely airtight system in order to function properly. A single gap between two components could result in a leak that could render your entire operation a great deal less efficient. This is the reason why constant maintenance is important, as regular checks will greatly reduce the occurrence of leaks and also increase the chances that any leaks that do develop can be quickly spotted and remedied.
If you suspect that a valve is leaking, then you will need to perform checks to ensure that the valve is still functioning as it should be. For two way and three way valves, turn the air supply off first and then remove the connections from the work and exhaust ports. Plug those ports firmly, then restart the air supply. Be sure to pay close attention to the area where the air supply hose is connected to the valve. If the valve leaks air and it is not leaking from the hose connection, then the valve is faulty and you will either have to repair or replace it.
For four way and five way valves, you will need to determine whether air is leaking from the valve itself or the equipment to which it is connected. One good way to do this is to remove the equipment and connect it to an air compressor directly. Turn on the air compressor and you will be able to determine whether the equipment itself is leaking air. If not, then reconnect the equipment to the valve and turn the air supply on. If air is leaking, then the valve is likely leaking and will have to be repaired or replaced.
In some cases, valves become stuck in the open or closed position. To determine what the problem is, you should disconnect the air supply and test the valve by hand. If the valve is able to cycle manually, but is not doing so electrically, then the most likely problem is that the pilot is in need of servicing or the electrical coil has been burned out. This type of problem usually requires immediate replacement.
While downtime is inevitable and you should always expect the unexpected with every system, there are ways to reduce downtime. One of the best ways to do that is to use only the very best equipment, such as Koganei pneumatic valves and Crouzet optical sensors, as these pneumatic components are built to the very highest manufacturing standards, thus reducing mechanical faults and possible downtime.
Malfunctions and downtime might be inevitable, but with Koganei pneumatic valves and Crouzet optical sensors available from DAS Services Inc, you will be assured a minimum of problems, and most troubleshooting sessions will show that these components are not the cause of your problems.
