You can find pneumatic systems almost everywhere from your car’s engine to industrial manufacturing and each of these systems will have to have a unique set of valves, fluids and drains. Finding the right drain valve can make the difference between a system which runs well and for a long time and having a system which constantly breaks down.
What Do They Do?
Pneumatic systems run through forcing fluid, such as air, oil or gas, into a closed system to increase the pressure and move a cylinder. Some of these systems can use combustion of the fluid to move the cylinder and others will just use increased pressure, but all can be harmed by the buildup of unnecessary fluid. This is where the pnuematic drain valve comes in handy. This valve is designed to let particulates and byproducts out of the chamber so they will not build-up and impede the system. This is especially useful in vehicle engines where moisture can affect the combustion.
Where Are They Used?
Not all pneumatic systems need drain valves, but most would benefit from them. Generally speaking, the more complex the system, the more valves are needed. Some systems have multiple valves for injecting lubrication, removing buildup and releasing pressure. It is a good idea to consult the schematics for your system and see how many of which types of valves are needed so you can have the right replacement parts on hand.
Where Do You Get One?
For some applications, you can pop down to your local hardware store and grab the right drain valve, but specialty equipment might need specific valves which are easier to find online. Your best bet is to see if there is a make and model on the valve needing replacement and find a new one that way. You can also contact the original equipment manufacturer or look for third-party parts suppliers who will have what you need. The more complicated your equipment, the more likely you are to need a very specific part and finding a reliable supplier is worth the time to research your options.
When you have a pneumatic system, it is a good idea to understand what types of valves it uses and where those are. This can help you make any repairs or replacements that you need before your system becomes too damaged. For instance, a drain valve helps keep moisture and particulates from building up in enclosed systems and blocking their functions. You can find specifications for various valve types as well as replacements online.
