A breather valve is a safety product usually found on storage tanks, Silos and Digester Tanks.
Also known as pressure/vacuum relief valves (PVRV), pressure/vacuum relief vents, or storage tank breathers, breather valves get their name because they allow the Storage tank to breath in and out when the tank is filling or emptying, or when temperature fluctuates in the atmosphere.
A breather valves most important function is safety. Many gases, liquids, and chemicals must be stored at the right pressure.
Failing to store them in a pressure-controlled tank can have grave consequences.
Generally speaking, if the pressure inside a tank gets too high, theres a chance the tank can rupture or explode. This can lead to a loss of containment, property damage, and loss of life.
Conversely, if the pressure inside a tank gets too low, it can create a vacuum. This can cause the container to implode with similar consequences.
A number of things can cause overpressure and vacuum conditions, including filling up or emptying tanks, changes in heat transfer, fires, and exothermic or endothermic reactions caused by mixing substances.
Breather valves open when the pressure inside the tank rises to the designated safe set point, allowing air to flow in or out to relieve the excess pressure or vacuum.
Aside from safety, breather valves can also:
Prevent wastage by evaporation and vapour loss
Protect the tank contents from external liquids and contaminants
Make it easier to store, transport, and discharge certain substances
A breather valve usually has two separate valves the out-breather and the in-breather.
When the pressure inside the tank reaches the pre-determined valve set point, the out-breathing valve will open to allow vapour release.
This will usually happen when the tank is being filled or if there is a rapid temperature change.
When the pressure inside the tank falls to the pre-determined vacuum set point, the in-breather valve will open to allow air into the tank and prevent the vacuum from exceeding the design limitations.
This usually happens when a tank is emptying.
The opening pressure of the valve is determined by a weight or spring-loaded mechanism.
This is calibrated to a specific pressure or vacuum, so when the internal pressure or vacuum exceeds the force applied by the weight or the spring mechanism, the valve will open. When the pressure inside the tank is below the set point of the valve, the valves are sealed tightly
There are several factors to consider when youre specifying a breather valve for your application.
Paying close attention to these considerations will help you protect your tank and its contents.
Breather valve size
Breather valves come in a variety of sizes. You must choose one thats appropriate for the size of your tank, the liquid or gas it holds, and the kind of flow you expect to see in and out of the tank.
Breather valve location
Breather valves are generally installed on the top of storage tanks. This helps protect the contents of the tank and prevent vapour leaks. Breather valves must be positioned so engineers can carry out inspections and maintenance operations with ease.
Breather valve inspection and maintenance
Breather valves need to be inspected and maintained regularly. At 3B controls, we recommend valves are inspected at least once per year for things like damaged diaphragms, corrosion, and potential blockages. Our team of trained service engineers can support and service all our supply equipment.

Understanding the intricacies of tank systems? One component that plays a pivotal role in maintaining tank safety and operational efficiency is the tank breather pressure valve. Delve into its world and discover its importance, types, and best practices.
drawing of breather valve with flame arresterA tank breather valve, often referred to as a vent valve, ensures that the pressure within storage tanks remains within safe limits. By allowing low pressure storage tanks to breathe, these valves prevent potential hazards due to overpressure or vacuum conditions.
Safety: Breather valves prevent catastrophic failures by releasing or letting in air to regulate pressure.
Product Quality: They minimize contamination from external sources by ensuring controlled airflow.
Operational Efficiency: Proper pressure management extends the lifespan of your tank and reduces maintenance costs.
breather valve in tankSelecting the right breather valve for your tank system is a crucial decision. Beyond just the type of valve, there are technical specifications and parameters to consider. Lets dive into the nitty-gritty details:
Set Pressure: Its the specific pressure point at which the valve starts to open to release excess pressure.
Set Vacuum: This refers to the predefined vacuum level at which the valve opens to let in air.
Ensure the chosen valves settings align with your tanks maximum allowable working pressure (MAWP) and maximum allowable vacuum.
Depending on the tank size and the rate of in/outflow, the valve should have an adequate flow capacity. This is typically measured in Standard Cubic Feet per Hour (SCFH) or liters/minute. It defines how quickly the valve can release or admit air.
The valve should be made of materials compatible with the stored substance. This prevents:
Consider the temperature range within which vacuum valve on the tank will operate. The valves materials and seals should be able to withstand and function efficiently within this range.
Breather valves come with various end connections such as flanged, threaded, or welded. The choice depends on the tank design, desired seal quality, and maintenance needs.
The seal ensures that the valve remains closed under conditions where its not supposed to act. Check the leakage rate to understand the seals efficiency.
Consider materials like Nitrile, Viton, or PTFE, depending on chemical compatibility and temperature ranges.
How much overpressure or underpressure can the valve tolerate before becoming damaged or dysfunctional? This factor ensures the valve remains operational even during unexpected scenarios.
A valves physical dimensions and weight might influence its compatibility with the tank, its pressure and vacuum relief especially if space is limited or if there are structural concerns.
Some valves, especially those with intricate designs like pilot-operated valves, might require more frequent maintenance. Ensure you have the resources to maintain the valve as required.
Ensure the valve meets any industry-specific regulations or standards, such as API, ASME, or others. Certifications can assure quality and reliability.
Factors such atmospheric pressure such as humidity, salt air (in coastal areas), or dust can affect the valves performance. Ensure the valve you select is suitable for your regions conditions.
breather valves with flame arrestors supplier (THINKTANK)Frequency: Breather valves should be inspected every 3-6 months or as per the manufacturers recommendation.
Visual Checks: Look for visible signs of wear, corrosion, damage, or blockages.
Operational Checks: Manually test the valve to ensure it opens and closes at the correct pressure and vacuum settings.
External Cleaning: Wipe down the valves exterior regularly to remove dust, debris, or any chemical deposits.
Internal Cleaning: Depending on the stored substance, internal residues can build up. Ensure internal components are cleaned using appropriate solvents or cleaning agents.
Over time, seals can degrade due to temperature fluctuations, chemical interactions, or simply wear and tear.
Check the seal for cracks, brittleness, or deformations.
Replace seals as required, and always have spare seals on hand for quick replacements.
Use calibration equipment to ensure the valve operates at the correct set pressure and vacuum levels.
Calibrate after any maintenance work or if there are operational anomalies.
Some valve components might require lubrication for smooth operation.
Use lubricants compatible with the stored substance to avoid contamination.
Ensure the valves airways remain clear. Blockages can prevent the valve from functioning correctly and pose significant safety risks.
Regularly remove any obstructions like debris, ice, or insect nests.
Maintain a log of all maintenance activities, including inspections, replacements, and any anomalies observed.
This record can help in predicting future maintenance needs and identifying recurring issues.
Ensure staff or personnel responsible for maintenance are adequately trained.
Regularly update training protocols to include any new maintenance practices or technologies.
Even with diligent maintenance, breather valves have a lifespan. Know the expected lifespan as given by the manufacturer.
If a valve shows consistent issues or reaches its end-of-life, replace it entirely.
If the tank is located in an area prone to dust, consider adding filters or protective covers.
For tanks in humid or coastal regions, check for corrosion more frequently.
Stay updated with the latest in breather valve technology. Upgrading to newer models or versions can offer better efficiency and safety.
