What is a Butterfly Valve? Working Principle, Types, and Applications
Where are butterfly valves used?
Butterfly valves are used in a wide range of industrial applications, including water and wastewater processes, treatment plants, fire protection systems, power plants, compressor lines, pipelines, heating and cooling systems, chemical and petrochemical facilities, marine industry, as well as the food and paper industries.
The primary reasons for preferring butterfly valves can be summarized as follows:
• Ease of Installation
• Takes up less space and is considerably lighter compared to other types of valves.
• Offers excellent sealing performance.
• Has significantly lower pressure loss compared to other valve types.
• Maintenance and repair are quite simple.
• Easy to open and close, with high operational performance.
• Designed and structured to be used in almost any process.
Gedik’s Expertise in Butterfly Valves
Butterfly valves, which are widely used in processes, get their name from the combination of a disc (flap) and a shaft. The simple structure, light weight, and small footprint of butterfly valves are the reasons why they are highly preferred. The materials used in the structure of butterfly valves may vary depending on the application and type of fluid.
Butterfly valves are mainly used in water and hot water processes. However, they are also preferred for compressed air, fluids containing solid particles, and dusty or corrosive fluids. Butterfly valves have a simple design. They consist of a body, a disc, a shaft, and a sealing element.
In butterfly valves, the disc is supported by a shaft along the vertical axis. The disc material can be made of stainless steel, spheroidal graphite cast iron, bronze, or other alloys. Stainless steel flaps provide durability and resistance to corrosive fluids. The sealing element material used in butterfly valves is generally EPDM, but depending on the fluid and temperature conditions, other materials such as Viton or NBR may also be preferred.
