There are generally two types of valves that seem to take center stage in the industry, two valves are butterfly valves and ball valves. While they look completely different from one another, they both really give very similar characteristics.
They both usually constructed from a combination of metals such as cast iron, stainless steel, and brass, they were both quite durable, have a long shelf-life, and are relatively inexpensive to purchase, and can both carry a variety of different gases and liquids in carrying temperature.

Some differences between the two both of the valves:
The main difference between the two types of valves is that they look different. The ball valve is basically a ball that has a hole going through it. While the butterfly valve consists of a shaft that has a rotating disk fitted onto it.
How They Function
A ball valve works by allowing open holes, blocked to regulate the flow of gas/liquid, while the butterfly valve using either disk allows the flow of gas/liquid through or to block it completely.
The pressure Involved
It is in this regard that the ball valve can be considered as a better option because the valve is always able to open easily despite any pressure that is placed upon it. Butterfly valves, on the other hand, can be difficult to change as part of the disc will always have to fight against the flow of gas/liquid.
The best use of their
Butterfly valves are cheaper than ball valves and easier to maintain. This is the reason that they are often used on large scale projects involving water flow regulation.
Although they both offer the same use, both ball valves and butterfly valves have different benefits and advantages for each other.
Fortunately, the leading valve manufacturers are usually more than happy to help with questions related to their products. All manufacturers will be able to provide some kind of advice you need before choosing between the valve ball and butterfly valves.
