Angle Valves: The Key to Optimized Flow Control in Industrial Applications

Hundreds of different styles of valves exist. This is not only because multiple industries use different valves for different purposes but also because within each of these industries, different applications call for different valve needs. Thus, many different styles of valves have been developed to address flow stoppage, control, pressure regulation, and the overall efficiency of the system into which they're integrated. 

Today, we'll be exploring the use, applications, and strengths of the angle valve. Angle valves are common across industrial settings to stop the flow to a specific fixture or area instead of the entire system and are commonly used in plumbing. Whether it's water, air, or chemicals, the angle valve is a key element in any system requiring total flow stoppage or control. 

Currently, the angle valves are widely used in both residential and industrial applications. Due to its nearly overwhelming popularity, it follows that choosing the right angle valve can make a big difference. The right-angle valve can help reduce maintenance downtime and improve system performance.

Let's learn more about the options and how to choose the right angle valve for your current needs. 

What Are Angle Valves and How Do They Work?

Small and triangular-shaped, angle valves are used to optimize flow control. 

With the angle-valve design, the inlet and outlet ports are at an angle to each other, usually perpendicular or at right angles. This unique shape not only gives the angle valve its name but also allows it to fit into tight corners. The key element in the angle valve is the twist handle that allows you to stop or control flow. 

Angle valves come in various sizes. Depending on the nature of the project and the size of the piping involved, you may need something smaller or larger.

Common sizes of angle valves include

• 1/4 inch – Used for small appliances, water filtration systems, or precise control in low-flow applications.
• 1/2 inch – A standard size for residential plumbing, including sinks and toilets.
• 3/4 inch – Often found in commercial plumbing and larger residential setups with higher water flow needs.
• 1 inch – Used in industrial applications and commercial HVAC systems.
• 2 inch – Designed for heavy-duty applications in large-scale industrial and municipal systems.

While the smaller sizes are more commonly found in homes and some commercial properties, the larger sizes are more commonly used for industrial applications.

But these size differences are not merely cosmetic. Different angle valves can also handle different amounts of pressure, a fact which should be taken into careful consideration as you make your selection.

Depending on the need, angle valves can be configured either as one-way, two-way, or three-way angle valves.

3 Key Components of Angle Valves

Three key components work together to allow angle valves to control the flow of various media, including water, air, or gas.

The Body

The body is an external casing that encloses all the valve's internal mechanisms except the handle. Though its composition is standard, different angle valves may carry distinct appearances, largely due to different materials that manufacturers may use depending on the needs of the project.

Common materials used for angle valve bodies include

• Brass. This is the most common material used for angle valves due to its durability and corrosive resistance. 
• Stainless steel. This style also offers excellent strength and corrosive resistance. It's also a preferred aesthetic for residential plumbing. 
• PVC. These valves are extremely cost-effective. 

Stem and Handle

The stem connects to the handle on one side and to an opening/closing component on the other. When attached properly to the body, the stem and handle work together to control flow regulation.  

The Seat 

The seat of the angle valve ensures a proper seal when the valve is closed. The most common materials used to make the seat include plastic and PTFE.  These materials are wear-resistant and produce an effective seal, particularly PTFE, which not only provides exceptional chemical resistance but also has a low friction coefficient.

Types of Angle Valves and Their Uses

Different angle valves are designed for different plumbing and industrial applications. They are generally easy to differentiate since they're usually named based on their opening and closing mechanisms.

Type 1: Angle Globe Valves

Angle globe valves use a plug mechanism for creating an on/off seal.  As the word globe may suggest, these valves require a full 360-degree turn to seal and unseal. The strength of the angle globe valves is that they create a strong seal suitable for lighter media.

Type 2: Angle Ball Valves

Turning the handle of an angle ball valve opens and closes a ball-type valve. This application is the best choice when you need quick shutoff capability.

Type 3: Angle Gate Valves

Angle gate valves have a disc (or gate) that rests on a seat with a stem to move it into and away from the seal.  Because these valves can withstand higher pressures, they're best suited for industrial use.

Type 4: Two- and Three-Way Angle Valves

Two- and Three-Way Angle Valves are used in complex fluid control systems. Typically labeled A and AB (in two-way) and A, B, and AB (in three-way), these valves allow for more flow options and can allow material to pass in different directions.  

Advantages of Using Angle Valves in Industrial Applications

Angle valves work across industrial applications due to a variety of factors.

1. Optimized Flow Control. Angle valves reduce turbulence and improve efficiency.
2. Compact Design. Due to their size and unique shape, they are ideal for space-constrained environments.
3. Durability and Reliability. Due to their form and materials, angle valves are generally resistant to high pressure and harsh conditions.
4. Versatility. Angle valves are ubiquitous for a reason. They're suitable for application in water, gas, oil, and chemical flow systems alike.
5. Safety Features. These valves prevent system overload and leaks.

Due to these many advantages, angle valves have found their way into many industrial applications.

Common Industrial Applications of Angle Valves

Due in large part to their durability, reliability, and versatility, angle valves are used in a wide variety of industrial applications.

• Manufacturing plants make use of angle valves in their automated production lines.
• The oil and gas industries use them to regulate high-pressure fluid flow.
• Wastewater treatment plants leverage the power of angle valves to control the flow of treated and untreated water.
• HVAC systems make use of angle valves to regulate their temperature control systems.
• Pharmaceutical and chemical processing centers rely on angle valves for the safe handling of liquids.

But though angle valves can be found across a wide variety of industries, that does not mean every angle valve is created equal. The application of the valve determines the material selection and valve type for each industry.

This means you must take care to select the perfect valve for your particular needs.

How to Choose the Right Angle Valve for Your Needs

First, consider the material compatibility.

• Brass is ideal for corrosion resistance and high-pressure applications.
• Stainless steel should be used to resist corrosion, high pressure, and high temperatures. 
• PVC is often the lightest and cheapest option, great for residential plumbing.

Next, understand your flow requirements. Because angle valves come with both high-pressure and low-pressure applications, it's imperative that you know the PSI needs and choose a valve that can withstand those pressures.

Third, you must evaluate which matters most: do you need fluid control or total shutoff abilities?

Finally, evaluate installation space and choose the correct size of angle valve to fit.

Why Angle Valves Are Essential for Industrial Flow Control

Choosing the right angle valve is essential for precise industrial flow control. The right valve can improve efficiency and safety through flow stoppage and control.

After gathering data on the type of material that would best suit your needs, your current flow requirements, and the space into which your angle valve will be installed, you're ready to take the next step.
