Even if you’re not familiar with what a valve is, chances are you have actually come across them before. There are even valves in your own home, after all. A valve is a device used for controlling the passage of fluid or air through a pipe or a duct and other channels. Naturally, there are countless different types of valves created to fulfill just as many unique functions. One of the most widely used types of valve is called a butterfly valve malaysia. Let’s find out more about this beautifully named valve.
What is a butterfly valve?
A butterfly valve is a device that controls the flow of materials inside large pipe sizes by rotating a disc quarter turn.. A rod runs through the center of a disc and is attached to an actuator that regulates the disc’s motion. The disc is either parallel or perpendicular to the medium flow. A butterfly valve differs from conventional valves in that the disc is constantly in the flow which creates a pressure change regardless of the valve’s position.
A butterfly valve gets its pretty name from how the movement of its disc is similar to the wing of a butterfly gearing itself for flight. The rod resembles the body of a butterfly while the disc moves like a butterfly wing. The action of a butterfly valve is similar to that of a butterfly that has landed with the wings moving up and down in a 90-degree motion.
Strangely enough, it is common practice to name valves after their appearance. For example, some valves are named for their shape like ball valves, globe valves and needle valves. Other valves are named for their movement and purpose such as a gate valve, a plug valve, a pinch valve, a life valve and a slide valve. A butterfly valve would fall into both categories. How unique!
What is the purpose of a butterfly valve?
Much like other types of valves, a butterfly valve controls the flow of media by beginning, slowing or stopping it. The disc rotates 90 degrees to open and close and is suitable for any compatible application. Fun fact: butterfly valves are frequently selected over other types of valves because it is less expensive and lighter in weight. Another fun fact: a butterfly valve is classified as a quarter-turn valve.
Extreme temperatures and rust are elements that can readily undermine a valve’s seal in specific procedures. Butterfly valves can tolerate extreme cold or heat which is also another reason why they’re such a popular choice. This means the butterfly valve’s seal retains its integrity which is crucial in high-stakes applications like energy generation and petroleum processing (as one leak could threaten public safety or the environment). Yes, valves are not just used in water filters and pipes but in countless other important industries as well such as ship building and food processing.
