Whether they are used in a petrochemical setting where a leak could be very bad for the environment or in a pharmaceutical lab where cleanliness and sanitation are very important, ball valve seats must be reliable and strong. The valve body, body cap, stem, hollow ball, and round ball valve seat make up a ball valve.

When the ball valve seat is installed, it serves as a seal and a distribution point for seating tension. Rubber or polymer is utilized as the seal material in soft seat ball valves, which are then installed onto metal seat rings as the valve’s seating material.

The advantages of this approach over hard seat ball valves are better sealing, lighter weight, and lower cost. This is why it’s so popular.

Purchasing ball valve seats for your next project? Whether you are setting up a huge lab or ready to build the biggest led light strip bulk production firm, here are a few things to think about:

1. Application

What do you want the media to accomplish for you?

Choosing the right ball valve for your application requires a thorough grasp of the task at hand, as they come in several designs and sizes.

2. Pressure And Temperature Scales

Determine the temperature and pressure of your media flow before picking a ball valve that is appropriate for your application. Understanding these factors is the greatest path to a valve that will suit your application needs.

It is important to note that temperature is a combination of both the media and the surrounding environment. The temperature will determine valve design and seal material. The media pressure differential (PSI difference between the two sides of the ball valve) is another thing to keep in mind while dealing with media. 

Typically, quality valve seals have a shorter life expectancy in applications with high-pressure differences.

3. Annual Cycles And Desired Lifespan Estimates

Determine how frequently you intend to cycle the valve. As soon as you know how many ball valves will be needed each year, you can decide how long each one should last. The vast majority of manufacturers don’t guarantee a ball valve’s and actuators’ life expectancy. 

This is because the application and medium will have an impact. The process for dealing with product faults if a provider offers a guarantee or warranty should be examined.

4. Media

What to keep in mind when it comes to the media:

  • Are you using self-lubricating oil, such as food oil or engine oil, in your manufacturing process?

Yes, abrasive material is present.

  • Is it possible that it’s anything wet, like air or gas, that’s the problem?

It’s possible to employ the valve as a “barrier” or “gate” without sacrificing the valve’s bubble-tight shutoff.

  • What are your expectations for maintenance, and can you afford to invest in a higher-spec ‘fit and forget’ valve with the best ptfe seat?

There are a lot of unknowns when it comes to media, but knowing this up front and expressing it to your supplier will help you choose the proper valve and reduce downtime.

5. How The Environment Affects 

A dust-free, temperature-controlled environment is not always possible while installing valves. As a result, consider the location of your valve. 

Wouldn’t a saltwater environment make sense for this? The majority of the day on a dry, sandy desert with high temperatures? Or is it underwater, functioning somewhere where there is a lot of quality pond filter foam, right? 

Even though the placement of the valve is inhospitable, it isn’t a disaster. It simply implies that the materials and especially the outside coatings and internal seals, will have to be able to survive the environment.

6. Noise

A Control Valve on high-pressure steam is a nice example of a valve that can make a lot of noise. This is not a problem if the valve is going to be installed inside an area that has good noise insulation. but it could be if it is going to be installed outside near residences and other buildings. 

There are low-noise trims available for these valves, but it’s preferable to get this figured out at the design stage because it can be a surprise to engineers.

7. Supports & Weight

Valves, by their very nature, tend to be quite large and cumbersome. Actuators and other controls on large bore valves can add up to more than 500 kilograms of weight. When building a system with huge valves, it’s important to take this into consideration because it puts a lot of strain on the pipes. 

In the case of ducting and HVAC systems, where the ducting is relatively light, this can be a problem. Weights in kilograms should be available from your supplier, just as they were for the valve measurements. They’ll figure out the total weight of your actuated assembly, including the actuator, valve, switch box, and any other ancillary parts.

Conclusion

Using a quarter-turn of the handle, a ball valve can be used to cut off a water supply quickly and easily. They are dependable and continue to function even after long stretches of inactivity. A wide variety of materials and designs are available for ball valves.

To find the optimum alternative for a particular application, look for and inquire about the ball valve possibilities.
