Choosing the Right Valve: Trunnion vs Floating.

If you're in the market for valves, you've probably come across the terms "trunnion" and "floating." But what do these terms mean, and which type of valve is right for your application? Don't worry, I've got you covered. Let's delve into the differences between trunnion and floating valves to help you make an informed decision.

Trunnion Valves.

1. Trunnion valves are designed with a stationary upper ball and a lower ball that pivots around a fixed shaft, known as a trunnion. .

2. These valves are ideal for high-pressure and high-temperature applications due to their robust construction and ability to handle significant pressures.

3. Trunnion valves provide better sealing capabilities compared to floating valves, making them a popular choice for critical applications where leakages are not acceptable. .

Floating Valves.

1. Floating valves have a single ball that is not fixed in place and floats between the valve seats to create a seal.

2. These valves are suitable for lower-pressure applications and offer easy maintenance and repair due to their simple design.

3. Floating valves are cost-effective options for applications where high pressure and temperature are not a concern.

Choosing the Right Valve.

Now that you know the differences between trunnion and floating valves, how do you decide which one is right for your needs? Consider the following factors:

1. Pressure and Temperature: If you are working with high-pressure and high-temperature applications, a trunnion valve is likely the better choice. For lower-pressure applications, a floating valve may be sufficient.

2. Sealing Requirements: If a tight seal is critical for your application, a trunnion valve is the way to go. However, if leakages are not a major concern, a floating valve could be a cost-effective option.

3. Maintenance and Repair: If ease of maintenance and repair is a priority for you, a floating valve's simple design may be more appealing. Trunnion valves, while durable, may require more maintenance due to their complex construction.

In conclusion, both trunnion and floating valves have their own advantages and disadvantages. It all depends on your specific application and requirements.
