About Butterfly Valves
Butterfly valves are a type of quarter-turn valve used to control the flow of liquids and gases in pipes. They are commonly used in applications where a quick on/off flow control mechanism is required, and where space and weight are limited. Butterfly valves are known for their simple design, low maintenance requirements, and low pressure drop, making them an ideal choice for many industrial applications.
Types of Butterfly Valves
There are two main types of butterfly valves: wafer and lug. Wafer butterfly valves are designed to fit between two flanges and are held in place by bolts. They are lighter and more compact than lug butterfly valves and are generally less expensive. Lug butterfly valves, on the other hand, have threaded inserts on each side of the valve body and can be bolted directly to the pipe flanges. They are often used in applications that require higher pressure or greater durability.
How Butterfly Valves are Made
Butterfly valves are typically made of cast iron, ductile iron, or stainless steel. The butterfly disc valve is the key component of the valve, and is typically made of metal or plastic. The disc is mounted on a shaft that passes through the valve body, and can be operated manually or with a motor. The valve body is designed to accommodate the disc and seal against leakage. Butterfly valves can be lined with a variety of materials to resist corrosion and erosion, and can be designed to handle a wide range of temperatures and pressures.
Industries that use Butterfly Valves
Butterfly valves are used in a wide range of industries, including oil and gas, chemical processing, water treatment, and HVAC. They are often used in applications where a quick on/off flow control mechanism is required, or where space and weight are limited. Professionals in these industries rely on butterfly valves to control the flow of liquids and gases in pipes, and to ensure that their systems operate safely and efficiently. The handle type and max vacuum capabilities are also important considerations when selecting butterfly valves for specific applications.
