In general, there are two types of valves that seem to take center stage in the industrial industry, those two valves are the butterfly valve and the ball valve. While they look completely different from each other, they actually both provide very similar features.
Both are generally constructed of a combination of metals such as cast iron, stainless steel, and brass, both are quite durable, have a long lifespan, and are relatively cheap to purchase, and both can carry a variety of gases and liquids at shipping temperatures.
For this reason, deciding which valve to use will come down to the small differences between the two options.
Design
The main difference between the two types of valves is that they look different. The ball valve is essentially a ball that has a hole through it, while a butterfly valve consists of a rotating shaft that has a disc mounted on it. Of course, your appearance should not be a reason to choose one or the other, but it is important to know.
How do they work
A ball valve works by allowing the orifice to open, block, or partially open to regulate gas/liquid flow, while a butterfly valve uses the disc to allow gas/liquid flow through or to block it. completely.
The pressures involved
It is in this case that a ball valve may be considered a better option since the valve can always open easily despite the pressure exerted on it. The butterfly valve, on the other hand, can be difficult to turn as part of the disc will always have to fight a flow of gas/liquid.
Its best uses
Because ball valves can offer a better seal, making them an ideal choice for use with gases. Butterfly valves may not be able to completely seal off gases, which could be a hazard in some industries.
Butterfly valves are cheaper than ball valves and are easier to maintain. That is why they are frequently used in large-scale projects that involve the regulation of water currents.
Conclusion
Although both offer similar uses, both the ball valve and the butterfly valve have different benefits and advantages from each other. This means that you will have to consider the benefits of each before choosing which valve to buy and use.
Fortunately, the major valve manufacturers are usually more than happy to help with inquiries related to their products. All manufacturers will be able to give you the type of advice you need before choosing between a ball valve and a butterfly valve.
