What is a Butterfly Valve Also Known As?
A butterfly valve is a type of rotary flow control valve that is used to regulate the flow of a fluid. Due to its small enclosures, fast working, and low price, it is have various other names in manufactures field and industry field as rotary valve, flap valve, disc valve, etc. The oil and gas, water treatment, HVAC, chemical processing and food and beverage industries are just a few examples of where such terms are often used synonymously with “butterfly valve”, although they can each denote certain specialised designs or application contexts.
In terms of construction, a butterfly valve has a disc that is connected to a shaft, which the disc rotates on, and when the valve is open, that disc rotates so that it is parallel to the flow and pressure drop can be reduced. For this simple and yet highly efficient design, there are many variations to cater for different media, pressures and installation conditions.
Types of Butterfly valve Among the most common types is the Lug Butterfly Valve , which has threaded lugs that secure the two flanges in place, without the need of nuts. A similar variation is the Cast Iron Lug Butterfly Valve which is a durable but economical option when it can be used in low pressure water and waste water applications. In the same vein, the Lug Style Butterfly Valve also makes for easy removal from either side of the pipe for convenient repairs and maintenance in complex piping layouts.
Other dominant types include flanged connections. The Manual Flange Type Butterfly Valve can be easily operated using a handwheel or lever, and the Stainless Steel Flange Butterfly Valve is highly corrosion resistant making it ideal for use with aggressive fluids. High pressure environment The Double Flanged Butterfly Valve is designed for excellent sealing and stability in higher pressure applications. The more straightforward Flanged Butterfly Valve is a common sight in industrial applications as it is easy to line up and provides a strong performance.
Grooved End Configurations Meet the Needs for Quick, Boltless Assembly. Popular items such as the Neutral Hub Type Butterfly Valve and the Rubber Bladder Type Butterfly Valve are also used widely in fire protection and building services. The Handle Grooved End Butterfly Valve offers manual convenience in tight piping run.
Material innovation builds out the family still further. The Stainless Steel Butterfly Valve is resistant to rust and high temperatures and the Halar Lined Pinless Butterfly Valve employs fluoropolymer lining to safely treat extremely corrosive chemicals. For the automation, there are Butterfly Valve Actuator and the Motorized Butterfly Valve available, to bring you remote and accurate flow control. High-pressure applications tend to call for High Performance Butterfly Valves designed for tight shut-off and long service life. And Keystone Butterfly Valves - a name synonymous with reliability in the most critical process industries - How are you protecting your piping systems?
Interestingly, a cousin product that is a part of this family is the Butterfly Check Valve, which utilizes a disc to prevent flow reversal, melding the simplicity of a butterfly design with the functionality of a check valve. In conclusion, whether they're referred to as a flap valve, disc valve or rotary valve, the adaptability of the butterfly valve is clear in all of its varieties - from Cast Iron Lug Butterfly Valves to high-tech Motorized Butterfly Valves. Each type has been engineered to meet particular performance requirements, which has resulted in butterfly valves becoming essential elements in fluid control systems around the world.
