What Are Angle Seat Valves & How Do They Work?

What Are Angle Seat Valves & How Do They Work?

What Is An Angle Seat Valve?

Angle seat valves are a type of solenoid valve that has a unique design that sets them apart from other solenoid valves. The valve's name comes from the angled seat located inside the valve body. This angled seat design allows for a smoother flow of fluid with minimal interruption while the valve is open. This results in an excellent flow rate and low-pressure drop, making them ideal for use in a wide range of demanding applications.


Typically, the optimal angle for an angle seat valve is 45˚ from the horizontal. This angle ensures that the valve can open and close smoothly, while also providing sufficient flow control.


Angle seat valves can be operated in two ways: manually or with the help of an electric actuator. Manual operation involves turning a handle to open or close the valve, while electric actuation uses a motor to do the same. Electric actuation is preferred in situations where the valve needs to be operated frequently or where remote operation is required.


How Does an Angle Seat Valve Work?

When the solenoid valve receives a signal to open the angle seat valve, it directs compressed air to the actuator. Once the actuator receives the compressed air, it propels the piston or valve plug upwards, ultimately breaking the seal with the valve seat. This action allows fluid to flow through the valve, thus opening the passageway for the liquid to travel through. However, when the signal is given to close the valve, the actuator moves the valve plug back down, thus re-establishing the seal and halting the flow of fluid.

This process allows for precise control of fluid movement, making these types of valves incredibly useful in a wide variety of industrial and commercial applications. The angle seat valve is designed with a high flow rate and low-pressure drop, making it ideal for applications that require efficient fluid transfer. Furthermore, the valve's design allows for easy maintenance and replacement of parts, ensuring that downtime is kept to a minimum.

Why Choose an Angle Seat Valve

There are several reasons why you might choose an angle seat valve over other types of valves. One of the main advantages of these valves is that they are highly reliable and durable. They are designed to withstand high pressures and temperatures, and they are less likely to leak than other types of valves. Additionally, angle seat valves are easy to maintain and repair, which can save you time and money in the long run.

Another advantage of angle seat valves is that they offer precise control over the flow rate of fluids. This makes them ideal for use in applications where accurate control is required, such as in chemical processing or food and beverage production. By adjusting the position of the valve stem, you can control the rate of flow with a high degree of accuracy.

If you're looking for a valve that can handle high flow rates and provide accurate control over fluid flow, then an angle seat valve might be the right choice for you. Our selection of ODE Angle Seat Valves caters to various industries and applications, providing exceptional quality and performance at an incredible value.

How to Choose Which Angle Seat Valve Is Right For You?

Now that you are convinced an angle seat valve is what you need, there are certain factors you must take into account to ensure you make the right choice. These criteria are vital to consider when selecting an angle seat valve that will suit your specific operational needs. Taking the time and doing your due diligence will help you make an informed decision and ultimately save you time and money in the long run.

Body Material

The material or the housing of the angle seat valve plays a large role in its durability and capacity to handle certain kinds of applications. The material should be compatible with the media flowing through it in addition to its environment. For example, if you are going to be using the valve in an environment where corrosive fluids will be flowing through the valve body, it is important to factor that in when making your decision. Our valves are constructed with AISI 316 stainless steel to meet the requirements of harsh environments so you can shop confidently knowing that you are covered.


Sealing Material

It's critical to select a material that is durable and meets your application's temperature and flow rate requirements. ODE angle seat valves come equipped with a PTFE (Teflon) seal, which can handle corrosive or high purity media by isolating all metallic components.


Thread Type

It's essential to choose the right thread in addition to selecting the correct sealing material. This will ensure maximum compatibility and minimize the risk of failure. We offer a range of angle seat valves that come with either an NPT thread or a BSP (gas) thread to provide extensive coverage. Opting for the appropriate thread will guarantee optimal performance in your specific application.



When choosing an angle seat valve, it's important to consider the method of actuation. This refers to how the valve will be opened and closed. There are two main types of configuration available. The first one is manual, meaning that you will need to physically operate the valve to open or close it. Alternatively, you can opt for a pneumatic actuator which can be remotely operated to swiftly open and close the valve. It's important to take into account your specific needs and requirements when choosing the right actuation method for your angle seat valve.

At Hydroponics Depot Inc., we provide a variety of angle seat valves that function pneumatically. However, we do not currently offer any angle seat valves that are operated manually. We are currently exploring the possibility of introducing manually operated angle seat valves to our online store.

Angle Seat Valve Applications

Water Treatment and Filtration:

Angle seat valves are a crucial component in water treatment and filtration systems, providing precise control over the flow of water and other fluids. They are commonly used in processes such as backwashing, where they facilitate the reversal of flow to clean and regenerate filters. The self-draining feature of angle seat valves is particularly beneficial in water treatment applications, preventing the accumulation of residual water and minimizing the risk of bacterial growth. Their reliable sealing and precise control make them well-suited for applications where maintaining water quality is essential.


Medical Equipment:

Angle seat valves find application in various medical equipment where precision control of fluid flow is paramount. They are commonly used in medical devices such as autoclaves, sterilizers, and laboratory equipment. The ability of angle seat valves to provide accurate modulation of flow rates is crucial in processes where maintaining specific conditions, such as pressure and temperature, is critical for the effectiveness of medical procedures.

HVAC (Heating, Ventilation, and Air Conditioning):

Angle seat valves are utilized in HVAC systems for controlling the flow of air, water, or other fluids to regulate temperature and maintain environmental conditions. They play a vital role in applications such as air handling units, where they modulate the flow of chilled or heated water to control the temperature of the air being circulated. The quick response and precise control offered by angle seat valves contribute to the overall efficiency of HVAC systems, ensuring optimal comfort and energy conservation.

Thermoforming Machines:

Thermoforming machines, used in the manufacturing of plastic products, require precise control over the flow of compressed air or cooling water. Angle seat valves are employed in these machines to regulate the pressure and temperature during the thermoforming process. Their ability to handle high temperatures and pressures, coupled with quick response times, makes them well-suited for the dynamic requirements of thermoforming applications.

Industrial Air Dryers:

Angle seat valves play a key role in controlling the flow of air through compressed air systems in industrial air dryers.
