Plug Valve vs Globe Valve – What’s the Difference
Have you ever wondered what the difference is between a plug valve and a globe valve? These valves are similar in many ways, but there are some key differences that you should be aware of when deciding which type of valve to use for your projects. In this blog post, we’ll take a closer look at each type of valve and explore the pros and cons of each.
What is Plug Valve?
A plug valve is one of the most common valves used in industrial applications due to its simple design and low cost. A plug valve consists of a cylindrical body with an opening for flow control and two plugs that fit into the body. When these plugs are opened or closed, they allow or block fluid from flowing through the valve.
The main advantage of using a plug valve is that it can be opened or closed very quickly with minimal effort—making it an ideal choice for applications where fast response time is essential. Additionally, plug valves are relatively easy to maintain and have fewer moving parts than other valves, making them more reliable over time.
However, one disadvantage of using a plug valve is that its design limits the amount of fluid that can flow through it at any given time; this makes it unsuitable for applications where high volumes of fluid need to be handled quickly.
What is Globe Valve?
Globe valves are another standard industrial valve used in many applications due to their ability to regulate the flow rate and pressure accurately. Unlike plug valves, globe valves consist of two discs (or “globes”) that move up and down inside the body to open or close the passage for flow control. This allows for greater accuracy when controlling the flow rate and pressure than what can be achieved with a plug valve—making them ideal for applications where precise regulation is necessary.
Globe valves also have fewer limitations in terms of maximum pressure than what you would find with plug valves—so they’re ideal if you need to handle high-pressure fluids. However, globe valves are generally more expensive than plug valves due to their complex design and larger size; they also require more maintenance over time due to their higher number of moving parts compared to plug valves.
Difference Between Plug Valve and Globe Valve
Ways of Working
Plug valves and globe valves work in different ways. Plug valves have a plug that fits snugly into the valve body. When the plug is turned, it opens or closes the valve. Globe valves have a disc that sits on top of the valve body. When the disc is turned, it opens or closes the valve.
Materials
Plug valves and globe valves are also made from different materials. Plug valves are typically made from plastic or metal, while globe valves are usually made from metal.
Sizes
Plug valves and globe valves come in different sizes. Plug valves are typically smaller than globe valves.
Applications
Plug valves and globe valves are used for different applications. Plug valves are typically used for smaller applications, such as in homes or small businesses. Globe valves are usually used for larger applications in factories or power plants.
Costs
Finally, plug valves and globe valves can cost different amounts. Plug valves are typically less expensive than globe valves.
Conclusion:
When deciding between a plug valve or vs globe valve for your application, there are several factors you need to consider before making your decision—including cost, ease-of-use/maintenance requirements, maximum pressure ratings, and accuracy required for flow rate/pressure regulation. Plug valves offer fast response times but limited top pressure ratings; meanwhile, globe valves offer greater accuracy but come with higher costs and maintenance requirements associated with their complex design. Be sure to carefully weigh all factors before choosing which type best suits your needs!
