Butterfly valve - Wikipedia
Large butterfly valve used on a hydroelectric power station water inlet pipe in Japan. Duplex valve in wafer butterfly configuration. A butterfly valve is a valve that isolates or regulates the flow of a fluid. The closing mechanism is a disk that rotates. Operation is similar to that of a ball valve, which allows for quick shut off.
Butterfly Valves: Uses, Types, Working, Advantages, Symbols
Butterfly valves belong to the quarter-turn rotational motion valves family and are used primarily to stop, regulate, or start the flow. The term “butterfly” in a butterfly valve is actually a disk that is connected to a rod.
What is a butterfly valve and where it is used in water supply
Butterfly valves are a family of quarter-turn rotational motion valves that are used in pipelines to shut-off flow. It is often said that butterfly valves can be used to regulate the flow. However, we do not recommend doing this, as it can damage the valve disk and have a negative effect on the sealing properties.
Butterfly Valve - an overview | ScienceDirect Topics
The butterfly valve is a rotary valve in which a disk-shaped seating element is rotated 90° to open or close the flow passage. They are used in throttling service, particularly where large-size valves with automatic actuators are required.
Butterfly Valve: Design, Working Principle, Types, Applications, …
Butterfly valves come in various types, each tailored to specific applications and operational conditions. The primary types include: Concentric Butterfly Valve: This type features a disc centered within the valve body, making it suitable for a wide range of fluids. It offers bidirectional sealing and is commonly used in water distribution systems.
Butterfly Valves Selection Guide: Types, Features, Applications ...
Butterfly valves are quarter-turn rotary motion valves used as throttling valves to control flow through a system. They can be used with many different media. Butterfly valves offer several advantages including quarter-turn, openness for less plugging, and good control capabilities.
An Overview of Butterfly Valves | Valve Magazine
2022年1月11日 · Butterfly valves offer a unique value proposition based on their weight, footprint, and cost effectiveness. They provide a variety of options from seat material, sealing designs, and range of temperature and pressure ratings. Butterfly valves offer one of the largest valve markets behind ball and gate valves.
Butterfly Valve Designs for High Performance and Long-Term …
3 天之前 · Some butterfly valves wedge the disc into a soft seat and rely on process pressure to provide reliable shutoff. Such valve designs only work with pressure on a particular side of the valve and will perform poorly in bi-directional applications. Other valves utilize seat designs that continuously wear as the valve moves, creating leakage after a ...
Butterfly Valve Explained - saVRee
Butterfly valves are fast acting (1/4 turn) rotary motion valves. This type of valve can be used to start, stop and regulate flow (throttle flow). Compared to other common process control valves (ball, gate, globe and plug), the butterfly valve offers significant advantages concerning weight and space savings.
Butterfly Valve | Quick Flow Regulation - Thermal Engineering
2024年5月25日 · Butterfly valves are a fundamental part of modern engineering, playing a crucial role in fluid management systems. Their primary function is to regulate the flow of fluids—ranging from gases to liquids—through a piping system.
