Pipes are everywhere. They carry water, air, gas, and many other liquids. To control how much liquid flows in a pipe, we use a special tool called a valve. One common type is the butterfly valve. Butterfly valves are called “butterfly” because the round disc inside looks a bit like a butterfly’s wings. Turning the…
In valve systems, an additional gasket is placed between the two flanges connecting the butterfly valve and the pipe during installation. It provides a seal and prevents leakage during system operation. Butterfly valve gaskets are typically made of flexible, corrosion-resistant materials that resist deformation, such as rubber, silicone, graphite, or composite materials. In addition to…
What is a butterfly valve stem? The stem is one of the core components of the butterfly valve, responsible for transmitting torque to drive the disc to rotate and realize the opening or closing function. Therefore, the choice of stem material directly affects the performance, life, and applicability of the butterfly valve. 1. Common stem…
Lug butterfly valves are great for controlling water and other fluids in pipes. They cost less than many other valve types. Additionally, they are well-suited for a wide range of jobs. Plus, they’re easy to install and maintain. This guide helps you pick the right lug butterfly valve for your needs.
The manufacturing process of the lug butterfly valve body includes the steps of flange connection surface, seat inlay surface, top flange and drilling, top and bottom holes of the valve stem, threaded hole of the valve stem top, lug ear drilling, deburring and threading. Lug butterfly valve body manufacturing process The manufacturing of the lug…
A wafer-type butterfly valve is similar to a quarter-turn valve with two or four non-threaded holes. These holes help hold the valve between two pipe flanges. A long bolt or rod goes through the flanges and the valve. When you tighten the bolt, the valve stays in place. The wafer-style butterfly valves prevent the fluid…

Butterfly valves are critical components in various piping systems, and understanding their pressure units is essential for proper selection and application. These units are categorized into nominal pressure (design pressure at a reference temperature) and actual pressure (working pressure under real conditions). They align with different standards, such as European (EN), Chinese (GB), American (ANSI/ASME),…
1. Valves and Water Flow Control Valves are devices that regulate, start, or stop the flow of liquids, like water, in pipelines. They work by opening, closing, or partially blocking the flow path. What is the Best Valve to Control Water Flow? The “best” valve depends on several factors: Application: Is the valve for home,…
Butterfly valves are crucial in many industries. They are used in water treatment, oil and gas, chemical processing, plumbing systems, and more. Their primary function is to regulate the flow of fluids through pipelines. Because they work in a challenging environment, they should be properly taken care of. If you do not maintain them, they…
