Benefits of Choosing the Right Quality Breather Valve (Pressure Vacuum Relief Valve)

Here at Assentech we feel we have a social, economic and corporate responsibility to our customers. This is why the quality of the valves we supply are epitomised as the benchmark standard for quality, reliability and efficiency.

A reputable supplier will ensure that the equipment is correctly sized, assembled using quality parts and comprehensively leakage tested before leaving the factory.

In order to promote safety and protect the environment, it is imperative that the correct tank venting equipment is selected to ensure:-

• Site operating efficiency
• Clean environment
• Safe working
• Improved profitability

Breather valves are safety devices that work as an end-of-line valve for protection against pressure and vacuum.

The quality of the equipment supplied will all contribute to the following:-

• A reduction in vapour loss – lessens any environmental impact
• A reduction of the ingress of water through condensation – prevents product contamination
• A reduction in the amount of toxic vapour – prevents adverse health effects on operators and the surrounding environment

When it comes to buying the right breather valves, it is important to make well-informed choices. Choosing the right breather valve for any application requires a proper evaluation. Do not base your decision solely around price. The actual cost difference between quality products and potentially unregulated products is relatively insignificant.

To make the right choices, consider the following points:

• Make sure that the vents are supplied with individual calibration and leakage certificates in accordance with ISO283000 or API2000. Manufacturers often provide calibration certificates only which is now in violation with API2000. Vent testing takes around 1 hour at the factory and many manufacturers don’t include it with each vent. At Assentech we ensure that the correct certification is included in our basic offering to ensure you remain compliant.
• Air cushioned sealing technology will improve the sealing ability and offer better emission control quality.
• Weights should be uniform and balanced – not just lumps of lead. They should also have the appropriate material for the process i.e. stainless steel for beverage applications.
• Choose the right diaphragms for superior compatibility/durability (FEP Teflon is a widely used material suitable for a variety of processes)
• Ascertain that the manufacturer has performed leakage testing on both the vacuum and pressure port for full compliance.
• Ensure that cover bolts are on the outside of the seal. This is a leakage path and the reason why few manufacturers certify leakage rates.

For reducing the leakage rates whilst fulfilling the industry standards – we recommend using Assentech sourced breather valves. We work with our appointed manufacturers to ensure components such as valves seats and pallets are made from high-quality material and lapped using highly developed manufacturing processes and testing.
