If you have worked for a long time in the pharmaceutical and beverage industry, you know how important the butterfly valve is. But do you really know how they work? Better yet, do you know the main parts that make a butterfly valve?
Butterfly valves are used to control the flow of fluids. The structure and mechanism of a butterfly faucet are both similar to those of a ball valve. This means a spherical disc with a hole and a rod that passes through the disc so that when the faucet is open, the fluid supposed to flow through it will flow transparently. When the faucet is closed, the flow will obviously be blocked. There are four main parts that allow the sanitary butterfly valves to work: the body, the seat, the handle and the operator. Most high-performance butterfly valves have bodies that can easily fit between two pipes. This allows the valves to increase productivity. Keep in mind that not all valves are the same. Some are designed for drinks while others are designed for pharmaceutical drugs.
The technology behind sanitary butterfly valves has grown steadily over time. This explains why valves are used in many industries today. The regular butterfly, for example, comes from the group or rather family of quarter-turn faucets in a wide range of sizes for different uses and handling different degrees of temperature and pressure. The larger the size of a butterfly valve, the more pressure it can withstand. Each part of a butterfly valve contributes in one way or another to its usefulness and functionality. The pieces depend on each other. In other words, the valve may not work at all if a part is damaged or develops a glitch. The two most important parts are:
• Disc – The valve incorporates the use of a large rotating disc as it is a control device. It serves as the main fluid passage that the faucet controls. A first use of the disc was mainly to control the flow of water in the plumbing systems. This is logical because the valve is designed to be used to isolate and regulate the jet of water and other fluids. Keep in mind that the faucet can also be used to control the entry and exit of air in car carburetors.
• Seat – The seat uses the inference adjustment between the edge of the disc and the seat to ensure that the valve stops. The seat can be stuck to the body or can be stuck. The seat materials can be made of polymers or metal. The metal is mainly used when the valve has to withstand extreme temperatures.
