The dispensing valve is usually the part of a system directly connected to the release of fluid. It works the same way as a water dispenser, it locks in the water until a mechanism is turned on and the dispensing valves work to release the fluid inside.
If it’s still not clear to you, then think of the human heart. How dispensing valves function is close to how the valves inside our hearts allow to blood enter and exit the heart. It’s the same logic, the same principle at work here too.
There are plenty of dispensing valves available, whether online or in local stores. If you know which type of dispensing valve you need, then good. If, however, you’re browsing through many kinds just to find what you think you need or think you must have, then make sure to do your research on each and every type of a dispensing valve you have your eyes on. Do that before you settle on one or two.
There are diaphragm valves as well as disposable fluid path valves so if one of these is what you need, you better know the difference between them. Or maybe it’s a positive-displacement valve that you should be looking over and not needle valves? Or maybe you’d like to give those spool valves on the bench a try?
Whichever type of valve you end up with, make sure it fits and is right for the system you need to use it for.
Also, do try to buy dispensing valves carried by brands or names you trust. There are quite a lot of poorly-made dispensing valves in the market. Sure, buying them now will save you a few bucks. But that’s only in the beginning. Soon enough, the wear and tear on that part is going to have you running back to the store to buy a new one.
So you end up not just wasting cash, you also waste your time. In addition, valves from trusted brands are tougher, more durable. So these parts last you longer and that saves you plenty on premature replacement costs alone.
Repair or Replace?
Others don’t buy new valves though. They simply spring for repairs. That could be a good temporary fix, especially if the damage to the valve isn’t extensive and money is a bit tight. However, repaired valves have a higher chance of failing than a brand new one. This could compromise system operations and even end up getting a leak because the valve isn’t as strong or durable as it used to be. If you don’t want problems like that, then buy new every time. And just to be safe, don’t settle for repairs.
