Product Introduction
In-line Breather Valve with Integrated Flame Arrester
In complex processes where tank exhaust gas is directed to recovery systems or centralized treatment pipelines, ensuring both pressure safety and fire isolation is a dual challenge. The In-line Breather Valve with Integrated Flame Arrester provides a perfect built-in solution. Installed in series between the storage tank and the recovery pipeline, it acts as both an "intelligent breather" for precise pressure regulation and an "active fire barrier" embedded in the pipeline, specifically designed for storage tank systems requiring closed venting and strict fire protection.
Integrated Function & Superior Performance
As an innovative product in the high-performance breather valve series, this valve integrates excellent overpressure/vacuum protection with efficient in-line flame arrestor technology. Under normal operating conditions, it responds sensitively to changes in tank pressure—opening to release overpressure gas and inhaling air to balance negative pressure, minimizing medium loss. The built-in flame arrester is directly installed in the breathing channel; in the event of flashback in the recovery pipeline or downstream system, it instantly quenches the flame and prevents reverse propagation to the tank, achieving intrinsic safety protection at the pipeline level.
Key Advantages & Customer Value
- Integrated Design Saves Space & Costs: The compact integrated structure eliminates the need for separate installation of a flame arrester, additional flanges, and support structures. It simplifies pipeline layout, reduces material and installation costs, and ensures a reliable and concise system.
- Top-Tier Sealing & Precision Control: Equipped with an advanced dual-guide valve core system, ensuring smooth operation and minimal wear. The leakage rate meets strict API 2000 standards, with an industry-leading ±3% set pressure accuracy, guaranteeing precise and reliable pressure regulation for stable process operation.
- Built-in Active Fire Protection: The integrated flame arrester complies with international explosion-proof standards, suitable for flammable gas groups such as IIA, IIB3, and IIC (per IEC/NEC standards). It provides direct and reliable flame arrestment, making it ideal for environmental protection systems like oil and gas recovery.
- Wide Operating Adaptability: Key components are made of corrosion-resistant and chemical-resistant materials, ensuring stable performance in harsh working conditions. It operates reliably within a temperature range of -45°C to +260°C, with flexible pressure settings (pressure: 0.35–100 KPa, vacuum: 0.2–4 KPa) to meet diverse project needs.
- Global Compatibility & Easy Maintenance: Available in a complete size range from 2 inches (DN50) to 12 inches (DN300). Flange connections comply with ANSI, HG/T20592 and other mainstream standards for seamless integration with various tank projects. The modular design allows on-site replacement of internal components, reducing maintenance difficulty and lifecycle costs.
Typical Applications
- Gasoline and chemical storage tanks equipped with Vapor Recovery Units (VRU)
- Fine chemical storage tanks with nitrogen blanketing and exhaust gas treatment systems
- Pharmaceutical and food industry process tanks requiring closed venting and fire protection
- All storage tanks where breathing exhaust is connected to a main pipe and requires fire isolation protection
