The ZXBV-I+ZGB Breather Valve with Flame Arrester is our premium “two-in-one” solution designed specifically for this purpose. By integrating a high-performance flame arrester directly with a precision-engineered breather valve, we provide a compact safety barrier that prevents external ignition sources from reaching the tank’s vapor space while allowing the tank to breathe safely.
Producdt Description
Our ZCPE-pilot operated breather valve with flame arrester represents a significant leap in tank safety technology. Unlike a traditional breather valve, the pilot-operated design ensures that seat leakage remains minimal even as the internal pressure approaches the set point. This allows for a full flow without overpressure, maintaining a precise tank pressure balance while significantly reducing product loss from medium volatility—making it a top-tier energy-saving solution.
Beyond pressure management, this system is built for reliability in extreme climates. By utilizing the principles of vapor heat transfer, we’ve ensured that critical breather valve components are protected from freezing, allowing for consistent performance in cold weather. Additionally, the integrated flame arrester provides a robust fire-retardant and explosion-proof barrier for the vapor space.
Every fire-resistant breather valve we produce features a simplified, corrosion-resistant structure optimized for high ventilation volume and low leakage. We use high-grade Polytetrafluoroethylene (PTFE) to provide superior low-temperature and anti-frost capabilities. For ultimate safety, each breather valve is equipped with an electrostatic protection device, ensuring the valve and the tank maintain the same potential at all times to eliminate spark risks.

Breather Valve with Flame Arrester Safety
Q1:How does a breather valve work with a flame arrester?
A1:The breather valve manages daily pressure and vacuum shifts, while the integrated flame arrester acts as a safety gate, quenching any external flames before they can ignite the tank’s contents.
Q2:Is this valve suitable for cold climates?
A2:Yes. The ZXBV-I+ZGB utilizes vapor heat transfer principles and frost-resistant materials to ensure that critical valve components don’t freeze, maintaining safe breathing even in sub-zero temperatures.
Q3:Does this unit meet international fire safety codes?
A3:Our breather valve with flame arrester is engineered and tested in strict accordance with safety standards, including explosion-proof and fire-retardant certifications required for global chemical storage.
Q4:How often should the flame arrester element be cleaned?
A4:We recommend a semi-annual inspection. Because our corrugated element is easy to access, your team can quickly clean or replace it to ensure zero-clog airflow and maximum fire protection.
Q5:Can I customize the set pressure for my tank?
A5:Absolutely. We calibrate each ZXBV-I+ZGB to your specific tank’s MAWP (Maximum Allowable Working Pressure) during the manufacturing process to ensure precise opening and closing.
