A Comparison of Pressure Relief Vents for Conservation Applications

Vents, also known as service vents, are essential features for the safe and efficient operation of storage tanks. These vents are designed to prevent excessive pressure or vacuum from building up in the tank, which can lead to structural damage or other safety issues.

In this blog post, we’ll discuss the different types of vents and their applications to help you determine which vent is best suited for your specific needs.

Types of Vents

Spring-Loaded Vents

Spring-operated vents are the most commonly used type of vent and are designed to maintain a constant pressure in the tank. They use a spring and a pallet to control the flow of gas into or out of a tank. These vents are best suited for low-pressure applications and are typically used on smaller tanks, such as oil and gasoline storage tanks.

Pilot-Operated Vents

Pilot-operated vents, on the other hand, are designed for higher-pressure applications. Unlike spring vents, they are equipped with a pilot valve that opens and closes based on the pressure in the tank. This allows for more precise control and keeps the tank pressure at a safe level, even during pressure spikes. These vents are often used on larger tanks, such as those used to store chemicals.

Choosing the Right Vent for Your Application

When selecting the right pressure relief valve for your application, the specific needs of the storage tank should be taken into consideration. Different types of tanks require different amounts of pressure relief. Selecting the wrong vent can create unsafe conditions.

For example:

• A spring-loaded vent may not be suitable for a tank that experiences frequent pressure spikes.
• A pilot-operated vent may be unnecessary for a smaller tank.

It is also important to ensure that the relief valve is sized correctly for your tank. An opening that is too small may not provide sufficient pressure relief, while an opening that is too large may allow too much gas to escape, leading to increased emissions and potential safety hazards.

Conclusion

In short, pressure relief valves are essential for the safe and efficient operation of storage tanks. Spring-loaded air vents are best suited for low-pressure applications and smaller tanks, while pilot-operated air vents are designed for higher-pressure applications and larger tanks. When selecting a pressure relief valve, always consider the specific needs of your tank and ensure it is sized correctly for optimal performance.
