The Ultimate Guide to Understanding Butterfly Valves | GMK
Butterfly valves are a type of quarter-turn valve used to regulate fluid flow. They consist of a circular disc that rotates around an axis perpendicular to the direction of flow. A stem is attached to the center of the disc, which enables it to open or close by turning it 90 degrees. When fully opened, butterfly valves offer minimal resistance ...
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.

Butterfly Valve Types | Complete Guide to Butterfly Valves
There are two types of actuated high-performance butterfly valves, just as there are major differences between globe valves and globe-style control valves. Many butterfly valves are built for remote operation in the shutoff or block mode, and these are generally standard high-performance butterfly valve types.
Check Valve
A check valve, also called a one-way valve, is a device that allows the flow of fluids to move only in one direction. The primary purpose of a check valve is to prevent backflow in the system. Check valves are cheap, effective, and easy solutions to a potential issue. Backflow can cause a problem if the flow is contaminated and, therefore ...
How Butterfly Valves Work on Vimeo
This 3D animated video explains how the butterfly valve works. We look at the valve''s main parts, how it functions and the advantages and disadvantages with this type of valve. Butterfly valves can be used to stop, start and regulate flow.
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.
What Is A Diaphragm Pump? | How does a …
A pump that uses the reciprocating action of a flexible diaphragm to pump the fluid is known as a diaphragm pump. The diaphragm is commonly made of Teflon, thermoplastic, rubber, or other flexible material. There …
Understanding Pneumatic Butterfly Valves
Several industrial applications involving liquids and gases rely on valves to control fluid flow and ensure efficient system operation. Pneumatic butterfly valves use compressed air to control fluid flow and they find applications in different sectors. We discuss how they work, the different types, and how they are used in different industries.
The Ultimate Guide to Understanding Butterfly Valves | GMK
What are butterfly valves and how do they work? Butterfly valves are a type of quarter-turn valve used to regulate fluid flow. They consist of a circular disc that rotates around an axis perpendicular to the direction of flow. A stem is attached to the center of the disc, which enables it to open or close by turning it 90 degrees.
Gate Valve VS Butterfly Valve: Key Differences
Gate valves generally have a higher butterfly valve VS gate valve pressure drop. The gate design creates turbulence and resistance in the flow, resulting in a higher pressure drop across the valve. This increased pressure drop can impact the system''s overall efficiency, especially in applications where energy conservation is a priority.
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.
Guide for Selection, Proper Use & Maintenance of Butterfly Valves
Butterfly valves are quarter-turn flow control devices that utilize a metallic disc that rotates around a fixed stem axis. They are quick-action flow control valves that allow rotations through 90 degrees to move from fully opened to a closed position. When the disc is perpendicular to the centerline of the pipe, the valve is at a closed position. The …

What is a butterfly valve and where it is used in water supply?
01. 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.
