What is a Butterfly Valve?

Butterfly valves can be considered the most popular choices among valves for industrial fluid control. The valves are essential to the flow control of liquids, gases, and slurries in various systems. Knowing the details of the working principle, type, and the advantages of a butterfly valve will enable you to make the most appropriate decisions for your project. The article we are going to discuss the term of the butterfly valve and its two types: the Handle Groove Butterfly Valve and the Wafer Gear Type Butterfly Valve.

What is a Butterfly Valve?

The butterfly valve is a type of valve used to control the flow in a pipe. A disc is rotated to let the liquid pass or to stop the passage of the liquid. The valve has got its name for its design that resembles the wings of a butterfly. The light weight, small size, and low cost of butterfly valves have led them to be commonly used for pipelines.

Key Components of a Butterfly Valve

• Body: The casing that is fitted between the flanges is called the body, which also gives the necessary support.
• Disc: The part in the center that has the ability to rotate and thus control the fluid flow.
• Stem: The part of the valve that connects the disc to the actuator or handle, so that the disc can be rotated.
• Seat: The part that becomes and remains tight and thus does not let the leakage occur when the valve is closed.

In this case, a valve is open only if the disc is in the same direction as the flow of the fluid and is parallel to it. Only changing the disc rotation to perpendicular to the flow creates the valve a seal, and therefore, the fluid flow is stopped completely.

Advantages of the valves with the Butterfly shape

• Compact Design: The butterfly valve’s compactness and lightness make it not only easy to handle but also less space-consuming.
• Quick Operation: They can be operated quickly by simply turning a quarter of a circle, so they are the best choice for the emergency situation where a shut-off is needed.
• Flexibility: it is possible for them to be used for a wide range of media e.g. water, air, steam, chemicals, and slurry.
• Reasonable: Butterfly valves are especially cost-effective for larger sizes, as compared to other types of valves.

Various Kinds of Butterfly Valves

Handle Groove Butterfly Valve

O Handle Groove Butterfly Valve is designed to be operated manually, and in this valve type, the fluid flow will be easily controlled.  Here are some benefits of this valve type:

• Easy Installation: The handle’s groove design makes it possible to easily have a connection with the grooved type of pipe fittings, thus simplifying the whole process.
• Good Sealing Performance: The sealing performance of this valve type is highly effective which means that there are no leaks and the integrity of the system is maintained.
• Flexible Applications: The Handle Groove Butterfly Valve is employed in various projects such as water supply, drainage, fire protection, and construction.

Wafer Gear Type Butterfly Valve

O Wafer Gear Type Butterfly Valve is a type that is very suitable for water treatment systems and industrial areas and is differentiated by its strong construction and advanced operation. Main features of this valve are:

• Compact and Light-weight: The wafer turnout design allows for a quick erection between the flanges, thus conserving space and consequently lowering the weight.
• Moderate Torque Requirement: The design reduces the operator’s input for turning the valve, thus confirming an easy-to-use product.
• Rugged Construction: A type of valve which is produced from high-quality materials; the product has the ability to work in different operating conditions, serve longer.
