The new type of breather valve is a major safety device installed on fixed-top storage tanks for crude oil, gasoline, kerosene, light diesel oil, aromatics, etc. It serves to prevent evaporation loss and protect the storage tank from damage when it is under overpressure or vacuum. This valve is usually used in conjunction with a flame arrester
Main features：
This valve features a large ventilation volume, excellent sealing performance, low leakage, and corrosion resistance.
Main technical parameters-Operating pressure：
Class A positive pressure :355Pa(36 mm water column) Negative pressure :295Pa(30 mm water column)
Class B positive pressure :980Pa(100 mm water column) Negative pressure :295Pa(30 mm water column)
Class C positive pressure :1765Pa(180 mm water column) Negative pressure :295Pa(30 mm water column)
Securing industrial storage tanks against dangerous pressure fluctuations requires a reliable All Weather Breather Valve. These heavy-duty industrial valves differ from standard commercial venting products. We engineer them specifically for the rigorous demands of the petroleum, chemical, and energy sectors. As a premier manufacturer, Zhejiang Naibang Valves Co., Ltd. (NIPO) delivers robust breather valve solutions. Our products maintain optimal internal tank pressure while preventing structural damage and hazardous emissions.
Backed by nearly 20 years of industry experience, our manufacturing process focuses on uncompromising quality. Every valve undergoes 100% pressure testing and 100% material inspection. This guarantees flawless performance in extreme environmental conditions. Our strict quality control system ensures each unit meets the highest industrial standards. This provides facility operators with ultimate peace of mind.
Finding the exact valve for your specific storage tank is straightforward with our comprehensive product range. Buyers can easily navigate our catalog by filtering through various materials and safety features. Whether your facility requires standard pressure regulation or advanced protection, our all weather breather valve lineup meets exact operational demands.
The longevity and reliability of an all weather breather valve depend heavily on its construction material. We offer premium stainless steel models that provide exceptional corrosion resistance. These are ideal for aggressive chemical processing applications. For durable and cost-effective solutions in petroleum storage, our carbon steel variants deliver outstanding structural integrity. Regardless of the chosen material, Naibang Valve conducts 100% material inspection on all components. This ensures absolute compliance with your media requirements.
Standard venting is not enough for facilities handling highly volatile or flammable media. We supply specialized explosion-proof all weather breather valves engineered to prevent catastrophic ignition events. Additionally, our catalog includes advanced models integrated with pipe and pipeline flame arrestors. These dual-function safety devices regulate tank pressure and extinguish external flames. This prevents fire from breaching the storage vessel, ensuring maximum protection for your infrastructure.
Partnering with Zhejiang Naibang Valves Co., Ltd. means choosing a supplier dedicated to quality, safety, and customer success. With nearly 20 years of specialized manufacturing experience, we serve as a trusted global partner for industrial valve procurement. Our commitment to uncompromising quality assurance includes 100% pressure testing and 100% material inspection on every product. We maintain transparent standards through a strict quality control system that openly welcomes third-party quality checking. Furthermore, our dedicated R&D team drives continuous innovation through significant annual investments in equipment. We also ensure quick global delivery and reasonable pricing, successfully exporting 40% of our owned brands worldwide.
Maintaining safe internal tank pressure in all weather conditions is a universal requirement across heavy industries. Our all weather breather valves are deployed globally. They protect critical infrastructure from overpressure and vacuum emergencies.
| Industry | Application Focus | Key Benefit |
|---|---|---|
| Petroleum Storage | Crude oil and refined product tanks | Prevents vapor loss and structural deformation during temperature shifts. |
| Chemical Processing | Volatile chemical storage vessels | Resists corrosive media while safely venting hazardous gases. |
| Ship Power Systems | Marine fuel and ballast tanks | Ensures stable pressure regulation in harsh, unpredictable maritime climates. |
| Energy Sector | General energy pipelines and transfer stations | Maintains continuous, safe flow and storage under varying environmental loads. |
We understand that standard off-the-shelf products cannot meet every industrial challenge. Naibang Valve excels in non-standard customization, offering tailored production directly according to client drawings. Our dedicated R&D team works closely with engineers and procurement managers. Together, we develop bespoke all weather breather valves that fit unique operational parameters.
