Angle Valve Vs. Gate Valve

The debate of angle valve vs. gate valve has been around for many years in the manufacturing world, and there are pros and cons to each type of valve. Angle valves are typically used in smaller-diameter piping applications, while gate valves are used in larger-diameter piping. Both valves have unique advantages and disadvantages, which must be considered before deciding. In this article, we will take a closer look at angle and gate valves, comparing and contrasting their features to help determine what dombor valve is right for the manufacturing application.

What Is an Angle Valve?

An angle valve is a valve that is installed at an angle, typically 90 degrees. Angle valves are often used in plumbing applications where space is limited. They are also used in applications where a regular valve, such as block and bleed systems, cannot directly regulate flow. 

It is often used in limited spaces, such as tight corners or small spaces. Angle valves can be made of various materials, including brass, stainless steel, and cast iron. They are available in multiple sizes and designs and can be controlled manually or automatically. Angle valves come in various styles, including industrial ball valves and check valves. Each type of angle valve has its advantages and disadvantages, so it is essential to select the correct valve for the application.

Angle valves have several advantages, including their compact size, ability to be installed in tight spaces, and easy operation. Additionally, angle valves are often less expensive than other valves and can be used for various applications, such as in plumbing, HVAC, refining and petrochemical, and industrial settings.

The operating principle of Angle Valve is based on the Bernoulli principle. The fluid (liquid or gas) flows through the valve at high speed when the valve is opened. The fluid exerts a force on the valve disc, which is equal to the fluid&#;s pressure multiplied by the area of the disc. This force tends to open the valve further. The outlet side of the disc has a lower pressure than the inlet side, so the fluid also exerts a force on the disc in that direction. This force is called the resultant force. The resultant force is what opens and closes the valve.

What Is a Gate Valve?

A gate valve is used to control the flow of liquids and gasses. It is a versatile valve used in various industrial and commercial applications. Gate valves manufacturer offer these valves in multiple sizes and materials, making them suitable for different applications. Some standard applications for gate valves include Pipelines, Water treatment plants, Chemical plants, Power plants, and Irrigation systems.

Some of the advantages of using a gate valve include:

• Gate valves are easy to operate and can be opened and closed quickly.
• Gate valves are durable and have a long lifespan.
• Gate valves can be used in high-pressure applications.
• Gate valves have a tight seal that prevents leakage.

The operating principle of a gate valve is straightforward &#; a gate is lowered into the path of the fluid to block it off. Gate valves are classified as either rising stem or non-rising stem valves. In a rising stem gate valve, the stem is connected to the gate and rises or lowers with the gate as it opens or closes. In a non-rising stem gate valve, either the stem is hollow and attached to the gate, or there is no correlation between the motion of the stem and that of the gate. Gate valves can be used in most typical service conditions. Thanks to their simple design, they are easy for users to identify if their function is open or closed based on visual or tactile inspection of the stem.

Many types of valves are available on the market, each with unique features and benefits. Two of the most popular valves are angle valves and gate valves. Both valves are used in various applications, but they have some critical differences. Here are some main differences between angle valves and gate valves:

• Gate valves have a ridge or wedge that slides into place to block the fluid flow, while angle valves have a disc that rotates to block fluid flow.
• Gate valves are typically used for thicker or more viscous fluids, while angle valves are better for thinner or less viscous liquids.
• Gate valves are less likely to clog than angle valves, making them a better choice for applications where clogging is a concern.
• Gate valves are more durable and have a longer lifespan than angle valves.
• Gate valves are more expensive than angle valves.
• Gate valves are more difficult to install than angle valves.
• Gate valves require more maintenance than angle valves.
• Angle valves provide a better seal than gate valves, making them a better choice for applications where leakage is a concern.
• Angle valves are more likely to leak than gate valves, making them less ideal for applications where the leakage is a concern.
• Gate valves are typically used in larger pipe sizes, while angle valves are used in smaller pipe sizes.
• Angle valves have a 90-degree operation, whereas gate valves have a linear process.
• Angle valves have a smaller face-to-face dimension as compared to gate valves.
• The Bonnet assembly of angle valves is welded to the body, whereas in gate valves, it is screwed.
• The disk of an angle valve is attached to the body with a pin, whereas in a gate valve, it is welded.
• Angle valves have better flow characteristics as compared to gate valves.
• The weight of an angle valve is lesser than that of a gate valve.
• Angle valves are easier to operate as compared to gate valves.
• Angle valves have relatively low thrust loads as compared to gate valves.
• The angle valve is a type of valve that is typically used for applications where a high degree of accuracy is required and is also known as chemical valve. On the other hand, the gate valve is a type of valve designed for applications where a large amount of fluid needs to be controlled.

How To Choose: Angle Valve Vs. Gate Valve

When choosing between an angle valve and a gate valve, there are a few things that need to be considered. Below, we outline five factors that will help to make the best decision for the needs.

• First, consider the type of fluid that is dealing with. If working with corrosive liquid, then it would be best to choose a valve that can withstand that environment.
• Next, think about the flow rate of the fluid. This will determine the size of the valve that is needed.
• Another essential factor to consider is the pressure of the fluid. This will affect the type of material the valve is made of.
• Take into consideration the temperature of the fluid. Different materials can handle different temperatures, so it is important to choose the right one for the application.
• Lastly, it would be best to consider the environment in which the valve would be used. If it is exposed to harsh chemicals or high temperatures, choose a material that can withstand those conditions.

Bottomline

When it comes to industrial valves, there are a variety of options to choose from. Two of the most popular types are angle valves and gate valves. So, which one is suitable for the application? The answer depends on several factors, including the characteristics of the fluid, the required flow rate, and the desired level of control. If still unsure which type of valve is right, contact us, and we&#;ll provide an expert consultation looking at the specific process and make a recommendation.

Marine Angle Valve:

-Angle valves are designed to change the direction of flow within a piping system. They have an angled body, typically 90 degrees, which allows the pipeline to change direction without the need for additional fittings.

-These valves are often used in locations where space is limited or where piping needs to make a sharp turn.

-Marine angle valves are suitable for regulating or stopping the flow of liquids, gases, or slurries in pipelines onboard ships.

Marine Globe Valve:

-Globe valves are named for their spherical body shape. They are designed to regulate or throttle flow in a pipeline. The flow of fluid through a globe valve follows an S-shaped or Z-shaped path, which creates a significant pressure drop.

-These valves offer precise control over flow rates and are often used in applications where flow needs to be regulated or where throttling is required.

-Marine globe valves are commonly found in various systems onboard ships, including water, steam, and fuel systems.

In summary, while both marine angle valves and marine globe valves are used in marine applications, they serve different purposes. Angle valves primarily change the direction of flow, while globe valves regulate flow rates. The choice between them depends on the specific requirements of the piping system onboard a ship.
