How Do Valves Work: A Simple Guide


Did you know that there is an existing valve installation regulation and requirements?

Even if you’re not an engineer, you are probably familiar with the most common types, since they appear in so many applications in our lives.

So, how do valves work, and what are they used for? To help you understand, we have put together this simple guide to the fascinating world of valves. Keep reading!

How Do Valves Work

The valve is a device that controls the flow of fluid or gas through a pipe. The most common type of valve is the ball valve, which is a lever that opens and closes a ball that is inside the pipe. The ball is attached to a handle, and when the handle is turned, the ball turns with it.

When the ball is turned so that it is perpendicular to the flow of the fluid, it blocks the flow and the fluid cannot pass through. However, if the ball is turned so that it is parallel to the flow, the fluid can flow through the pipe.

The Different Types of Valves

There are many different types of valves, each with its own unique purpose. The most common type of valve is the ball valve, which is used to control the flow of fluids.

Other types of valves include check valves, which prevent backflow, and butterfly valves, which are used to regulate the flow of liquids or gases. 

Sanitary butterfly valves consist of a disk that is mounted on a shaft. The disk is attached to the body of the valve with a butterfly nut. The disk has a hole in the center that allows the liquid or gas to pass through. The disk can be rotated to open or close the valve. 

A globe valve consists of a round body with a disk-shaped element that can be rotated to open or close the valve. The disk is attached to a stem, which is connected to a handle that can be used to operate the valve.

Globe valves are used in a wide variety of applications, including in oil and gas pipelines, water pipelines, and HVAC systems.

The Different Types of Materials Used in Valves

Valves are designed and manufactured in a wide variety of materials to suit the many different applications they are used for.

The three most common materials used in valves are cast iron, brass, and stainless steel. Cast iron is a strong, durable material that is often used in heavy duty applications such as water and wastewater treatment.

Brass is a softer metal that is easy to work with and is often used in plumbing applications. Stainless steel is a strong, corrosion-resistant material that is often used in food and beverage processing.

Valves are essential for the proper functioning of many different types of machines. At their most basic, valves allow for the flow of fluids and gases in a controlled manner.

Without valves, many of the machines that we rely on in our daily lives would not be able to function. If you’re interested in learning more about how valves work, make sure to read this simple guide.
