Everything You Need to Know About Orbit Plug Valves

2023-04-30 By ren


Are you in need of a reliable valve for your industrial operations? Look no further than the Orbit Plug Valve. These valves are designed to provide efficient and effective control over flow rates, making them an essential component for many industries. Whether you’re dealing with corrosive chemicals or abrasive slurries, Orbit Plug Valves can handle it all. In this post, we’ll dive into everything you need to know about these versatile valves – from how they work to their various types and installation process. So let’s get started!

What are Orbit Plug Valves?

Orbit Plug Valves are a type of quarter-turn valve that feature a cylindrical or conical plug to control fluid flow. The plug can rotate inside the valve body, which allows for precise and efficient control over the flow rate. These valves are commonly used in applications where high-pressure drops or abrasive fluids are present.

The main advantage of Orbit Plug Valves is their ability to provide bubble-tight sealing, even at high pressures. This makes them ideal for use in industries such as oil and gas, chemical processing, and power generation.

Orbit Plug Valves come in various sizes ranging from ½ inch to 24 inches in diameter. They can be made from different materials such as cast iron, bronze, stainless steel, and others depending on the application requirements.

One important thing to note is that Orbit Plug Valves require regular maintenance to ensure optimal performance. Maintenance usually involves lubricating the valve stem and plug assembly with suitable lubricants.

Orbit Plug Valves offer a reliable solution for controlling fluid flow in many industrial applications thanks to their efficient design and impressive durability.

How do Orbit Plug Valves Work?

Orbit plug valves are a type of industrial valve that controls the flow of fluids in pipelines. They work by using a cylindrical or spherical shaped plug that rotates within the valve body, opening and closing to regulate the fluid flow.

When the valve is open, fluid flows freely through the passageway between the plug and valve body. When it’s closed, however, the plug forms an effective seal against pressure from both directions.

This design ensures that orbit plug valves can handle high-pressure applications with ease. It also makes them suitable for controlling corrosive and abrasive fluids without any damage to their components.

The operation of orbit plug valves is typically manual or automatic. For automatic control, electric actuators or pneumatic cylinders can be used to operate them remotely based on set parameters like pressure, temperature or level sensors.

Orbit Plug Valves provide reliable operation and tight shut-off capabilities making them ideal for use in various industries including oil & gas production facilities, chemical processing plants as well as power generation plants where they offer superior performance compared with other types of valves.

The Benefits of using Orbit Plug Valves

Orbit plug valves have several benefits that make them a popular choice for industries that require efficient and reliable fluid flow control. One of the main advantages of using orbit plug valves is their ability to handle high pressures and temperatures, making them suitable for use in demanding applications.

Another benefit of orbit plug valves is their low operating torque, which means they can be easily operated even with minimal force. This feature also reduces wear and tear on the valve components, extending the lifespan of the valve.

Orbit plug valves are also known for their tight shutoff capabilities, helping to prevent leakage and improve safety in industrial processes. The self-cleaning action provided by the rotational motion of the plug helps to remove debris from the sealing surfaces, further enhancing its sealing performance.

In addition to these functional benefits, orbit plug valves are designed with easy maintenance in mind. With fewer moving parts than other types of valves, they require less frequent repairs or replacements and provide cost savings over time.

The numerous benefits offered by orbit plug valves make them an excellent choice for various process industries where efficiency and reliability are critical factors.

The Different types of Orbit Plug Valves

Orbit plug valves come in various types, each with unique features and capabilities. One type of orbit plug valve is the standard port valve, which has a small opening that restricts flow but provides better control over process parameters. On the other hand, full port valves have larger openings that allow for unrestricted flow and less pressure drop.

Another type of orbit plug valve is the multi-port valve, which enables users to connect multiple pipelines or divert flow from one pipeline to another. Three-way valves can regulate flow between two different lines while four-way varieties combine both three-way functions into a single unit.

For applications where tight shutoff is essential, eccentric plug valves are often used as they provide an effective seal even if debris accumulates around the disc area. High-performance butterfly valves are also sometimes referred to as orbit plugs because they use circular discs instead of traditional flat ones.

In addition, some manufacturers offer customized solutions such as lined or jacketed orbit plug valves for handling corrosive fluids or extreme temperatures. Ultimately, selecting the right type depends on factors such as process requirements, fluid characteristics and operational conditions.

How to Install an Orbit Plug Valve

The installation process of an Orbit Plug Valve is relatively simple, but it requires precision to ensure proper functioning. Before you begin the installation, make sure that you have all the necessary tools and equipment.

Firstly, check the valve body for any defects or damages that may affect the performance of the valve. Next, clean both ends of the pipe where the valve will be installed using a wire brush or sandpaper to remove any debris.

Apply Teflon tape or sealant on both ends of the pipe threads before screwing in the valve. Tighten with a wrench until snug, making sure not to over-tighten as this may damage or deform internal components.

Once installed, open and close the orbit plug valve several times to test its operation and ensure there are no leaks. If everything works well, turn off any remaining valves upstream from your newly installed one.

In summary, installing an Orbit Plug Valve requires attention to detail and proper handling of tools and equipment. Always follow manufacturer’s instructions carefully for optimal results when installing these valves!


Orbit Plug Valves are essential components in various industries that require flow control. They offer many benefits such as durability, reliability, and ease of maintenance. When selecting an Orbit Plug Valve, it is crucial to consider the type of valve suitable for your application.

Additionally, proper installation and regular maintenance practices can ensure optimal performance and longevity. With this guide on everything you need to know about Orbit Plug Valves, you can confidently choose the best valve for your operation’s needs.

Always remember to seek professional assistance when in doubt or unsure about any aspect of using or installing these valves. With proper use and care, Orbit Plug Valves will deliver dependable service over an extended period with minimal downtime.
