A short guide on Valves and Fittings material selection

Given the information, we all know regarding the properties of materials that are commonly employed in seals, valve bodies, and O-rings, the material selection process is becoming a routine. The most challenging part of deciding material choice is verifying that the material you have selected fits the application.

How to choose the right valves and fittings

As a plant manager or fluid system manager, you have to be fully aware of all your system requirements. You must consider the fluid, temperature, pressure and several other factors. It is imperative that you choose valves and fittings that are kp-lok.com constructed with the right materials. If you do your detailed research before making a purchase, you will save your system from a failure, and you will also save money.

Compatibility should be your priority

When it comes to industrial valves and fittings, it is best that you go for the best available material, but you shouldn’t make that your only priority. When it comes to choosing industrial valves and fittings, you should also consider compatibility. In fact, compatibility is the first thing you should find when purchasing sealing products. Incompatible components will result in operation failure. So you should always think of compatibility.

You should develop in-house material selection model to pick what is best and what is not best. For example, stainless steel components are the most resistant and widely compatible options there is, however stainless steel is not universally compatible. Stainless steel often works well in aggressive conditions, but that does not mean that they will always be suitable for the hostile environment. For example, the 316 stainless steel products will perform if the system involves the use of nitric acid, but they won’t work well and might fail if the nitric acid replaced by sulfuric acid.

How to ensure chemical compatibility

Several industries use a range of chemicals and other materials. So no one expects you to know what works for each of the systems. However, once you order a sealing product, you have to make sure you know the specific application requirements. This information is easily assessable via online resources. Although if you are working with hydrogen, nitrogen or compressed gas, there is no compatibility issue!

Coat it once or twice!

You don’t need to worry about sealing products made of 316 stainless steel are highly reliable. They ensure optimal performance, and they fit well with most systems. However, if your process involves chemicals that make it very difficult to use stainless steel products, opt for a coated component. PTFE and other coatings are excellent to use.
