An Overview of Butterfly Valves | Valve Magazine
Butterfly valves belong to the family of quarter-turn rotational valves, created and first used in steam engine prototypes as early as the 18th century. Use of butterfly valves grew in the 1950s for applications in the oil and gas market, and 70 years later they continue to be widely used in numerous industrial applications.

What is a Butterfly Valve? | Tameson
Butterfly valves are quarter-turn valves that are popular for on-off or modulating services. They are lightweight, have a small installation footprint, lower cost, quick operation, and are available with large orifice sizes. The "butterfly" is a disk connected to a rod. When the valve opens, the disk rotates to allow fluid to pass through.

It is used to cut off, connect and regulate the medium in the pipeline, with good fluid control characteristics and closing sealing performance. 2、Butterfly valve can transport slurry and accumulate the least liquid at the mouth of the pipeline. Good sealing can be achieved under low pressure.
Butterfly Valve Basics: Anatomy and Design
The working principle of a butterfly valve is simple. As the disc rotates, it either allows or restricts the flow of the fluid. When the disc is rotated perpendicular to the flow, it blocks the flow completely.
The working principle of the ball valve (GIF)
The structure principle of the ball valve: 1. The ball valve is not restricted by the installation direction, and the flow direction of the medium can be arbitrary. The fluid resistance is small, and the full-bore ball valve basically has no flow resistance. 2.
Butterfly Valve: Types, Parts, Working principle, Advantages
A butterfly valve, known for its quarter-turn functionality, relies on a disc mechanism positioned within the pipeline to manage the flow of liquids or gases. This disc, firmly attached to a shaft, resides at the heart of the valve assembly. The operation of a butterfly valve involves a 90-degree rotation of the disc.
Basics of Butterfly Valves | Animation of Butterfly Valve
The "butterfly" is a metal disc mounted on a rod. When the valve is closed, the disc is turned so that it completely blocks off the passageway. When the valve is fully open, the disc is rotated a quarter turn so that it allows an almost unrestricted passage of the fluid. The valve may also be opened incrementally to throttle flow.

4. According to the shape of the valve body, it can be divided into ordinary electric valve and micro electric valve. The working principle of the electric valve: The electric valve is connected by the electric actuator and the valve. After installation and debugging, the valve is driven by the power supply to realize the opening and closing
Valve Design and Working Principle of Butterfly Valve
Butterfly Valve Working Principle. It is based on the quick shut off principle. The disc of the valve is placed in the center of the pipe which allows a rod to go through it to an actuator, on the outer side of the valve. The disc remains parallel or perpendicular to the flow. A pressure drop is introduced by the disc upon the flow even
Working principle diagram of three-way valve
Principle of three-way valve: When the valve opens, the medium enters the valve from A, and flows out of the valve through B. When the bypass requires medium to flow in, the actuator is opened, the valve core is reversed, and medium A enters C out. When the pipeline does not require medium to flow in, the actuator is opened and the

How It Works: Butterfly Valves | SLB
In other words, a butterfly valve consists of a circular disc or plate built with a stem through the middle or attached offset. When opened, the disc pivots 90° in the valve bore, aligning with the flow and creating a nearly unrestricted flow path. Like ball valves, butterfly
Butterfly Valve vs Ball Valve: Major Differences between a Ball Valve and a Butterfly Valve
Butterfly valves are lightweight, have the least parts, and require little support. Similarly, they are cheaper than ball valves, especially beyond a certain diameter size. However, they aren''t suitable for high-pressure applications since high-pressure differences between

Operation is similar to that of a ball valve, which allows for quick shut off. Butterfly valves are generally favored because they cost less than other valve designs, and are lighter weight so they need less support. The disc is positioned in the center of the pipe. A rod passes through the disc to an actuator on the outside of the valve. Rotating the actuator turns the disc either parallel or perpendicular to the flow. Unlike a ball valve, the disc is always present within the flow, so it ind

Butterfly Valves: Function, Types, and Applications
A butterfly valve is a type of quarter-turn valve that is used to control the flow of fluids, typically in pipes carrying water, air, gas, or other fluids. It gets its name from the shape and movement of its disk, which is similar to a butterfly''s wings. This disk, mounted on a control rod, is the key component of the valve.
The Working Principle of Butterfly Valve
The butterfly valve is a valve that uses a circular butterfly plate as a switch part and rotates with the valve stem to open, close and adjust the fluid passage. The butterfly plate of the butterfly valve is installed in the direction of the pipe diameter. The butterfly plate rotates around the high pressure, and the rotation angle is between 0
Flow Control Valves: Diagram, Types, Working & Uses [PDF]
In hydraulics, flow control valves are used to control the amount of oil supplied to various parts within a hydraulic system. In this way, the momentum of a cylinder or the rotational speed of a hydraulic motor can be controlled. However, a basic flow control valve has an opening that can be changed to increase or decrease the flow rate.
