While buying a general twin seal valve might seem like a breeze, there are various things you still need to keep in mind. These factors will ensure that you get the right valve and that it serves the purpose it was meant to serve. The one thing that will direct all the decisions you make concerning the valve is the function of the valve.
Based on what you plan to use the valve for, everything else will have to be considered; you will get a certain type of valve. If you plan on using it in a place that has high-pressure oils or gases flowing through, then the quality and type will be different from valves used with low-pressure oils and gases. If you have no idea what you should be looking out for, these pointers will come in handy for you.
- Valve Size
While this may be a no brainer, there is often room for error here. Before you go out to buy the valve, check the pipes it will be joining and note the size. The good thing with valves is they come with the sizes written on them. One thing you need to
remember, however, is that the smaller the valve size, the higher the pressure of the oil or gas flowing through it.
- Valve Material
One very essential factor you should not miss is the material used to make the valve. This will determine how long the valve will function correctly and whether it is safe enough to use in the environment you plan to use it in. One way to be sure you are using quality valves is by having it examined by an engineer. This comes especially
in handy if you are dealing with corrosive substances that may cause an accident when mishandled.
Alongside the material used to make the valves, you must ensure the valves last for long. The one way of ensuring this is by getting quality material valves. High-grade trim materials will help ensure you get the most use out of your valves.
- Maximum Leakage Rate
Valves are sometimes not checked when they are in use. For this reason, issues are bound to arise when there is a high leakage in the valves. Before you buy the valves, find out what the maximum leakage rate is. Also, find out what is the least amount of leakage a valve should have so you do not have a faulty valve.
While this might go without saying, the cost of the valves you buy will also determine what you settle for. In this case, however, you must choose quality over money.
Where need be, you should go for an expensive valve that will serve its purpose. It beats the hassle of having to replace the valves after a short period. Double block &
b leed valves and other types in the market vary in pricing depending on the brand and many other factors.
