Product Introduction
End-of-Line Breather Valve with Built-in Flame Arrester
In the petrochemical, pharmaceutical, and fine chemical industries, safe ventilation and fire protection of storage tanks are two core requirements. The End-of-Line Breather Valve with Built-in Flame Arrester innovatively integrates these two functions into one, providing a one-stop compact safety solution. Installed directly on the flange at the top of the storage tank, it is both an "intelligent lung" that maintains pressure balance inside the tank and a "solid shield" that resists external flame intrusion. It is specifically designed for storage tanks that require direct discharge to the atmosphere and strict fire protection.
Integrated Functions & Superior Performance
As an outstanding representative of the high-performance breather valve series, this product far exceeds ordinary standard valves on the market. It perfectly combines the overpressure/vacuum protection of a breather valve with the flame blocking function of a flame arrester. Under normal operating conditions, it precisely controls the "breathing" of the storage tank, prevents damage to the tank body caused by overpressure or vacuum, and significantly reduces medium volatilization loss. Once an external flame threat approaches along the discharge path, its built-in high-efficiency flame arrestor core can immediately quench the flame, completely preventing the fire source from entering the valve housing and the interior of the storage tank, and nipping the explosion risk in the bud.
Key Customer Value
- Space & Cost Savings: The compact integrated design, compared with the traditional scheme of separate installation of breather valve and flame arrester, greatly reduces installation space, pipeline connectors and total weight, and lowers installation and material costs.
- Superior Sealing & Precision: Equipped with an advanced dual-guide valve core system, ensuring stable operation and extremely high sealing performance. Its leakage rate is well below the strict API 2000 standard, and it maintains ±3% high set pressure accuracy, ensuring the precision and reliability of storage tank pressure control.
- Strong Safety Protection: The integrated flame arrester complies with international explosion-proof standards and is suitable for various flammable gas groups such as IIA, IIB3, and IIC (IEC/NEC), providing direct and reliable fire protection for storage tanks storing flammable and explosive media.
- Wide Operating Adaptability: The internal components of the valve are made of corrosion-resistant and chemical-resistant materials with stable performance. The product has a wide operating temperature range (-45°C to +260°C) and a flexible pressure setting range (pressure: 0.2-5 KPa, vacuum: 0.2-100 KPa), adapting to various harsh environments.
- Global Installation Compatibility: A complete size range from 2 inches (DN40) to 12 inches (DN300) is available. Flange connections support internationally common standards such as ANSI and HG/T, ensuring seamless docking with storage tank projects around the world.
Typical Application Scenarios
- Fixed-roof storage tanks for flammable liquids (such as gasoline, solvents, and chemicals).
- Process storage tanks in the pharmaceutical and bioengineering industries that have dual requirements for cleanliness and safety.
- Emergency relief and fire protection for storage tanks adopting nitrogen blanketing systems.
- Any storage tank vent that requires simultaneous pressure regulation and fire isolation, and directly discharges to the atmosphere.
