Poppet valves and ball valves are two common types of valves that are used in a variety of applications. Although they look very similar, they have some essential differences that make them suitable for different situations. This blog post will look at poppet and ball valves to see what sets them apart.
Poppet valves are generally known as “check” or “shutoff” valves due to their primary purpose of blocking the flow of liquids or gases. They consist of a circular disc with a stem attached and surrounded by a spring-loaded housing. The disc opens up when the stem is pulled up and allows fluid or gas to pass through. When the branch is pushed down, the disc closes off any flow from going through. This makes poppet valves ideal for applications that need to be shut off quickly or when precise control over the flow rate is required.
Ball valves have been around since the 1940s and have become one of the most popular types of valves used today due to their low cost, durability, and ease of use. They consist of a round sphere with a hole that can be opened or closed by rotating it 90 degrees on its axis using an external handle. This makes ball valves perfect for applications where you can quickly switch between open/close positions without much effort. Additionally, ball valves are more reliable than poppet valves because there is no spring inside, which can break over time.
Difference Between Poppet Valve and Ball Valve
- Poppet valves have a cylindrical or spherical body with a hole in the centre.
- Ball valves have a spherical body with a hole in the centre.
- Poppet valves are opened and closed by a plunger that moves up and down.
- Ball valves are opened and closed by a lever that turns a ball inside the valve body.
- Poppet valves are typically used for high-pressure applications, while ball valves are typically used for low-pressure applications.
It’s essential to understand the difference between poppet valves and ball valves when selecting one for your application. Poppet valves are excellent for applications where precision control over flow rate is needed. In contrast, ball valves are better suited for quick open/close operation with less maintenance. Both offer unique advantages depending on your specific requirements, so do your research before deciding!
