The ZCBV-IZ Breather Valve With Inside Elements is an all-in-one safety solution designed to protect atmospheric and low-pressure storage tanks. By integrating a high-performance Flame Arrester directly within the breather valve housing, this unit provides essential pressure and vacuum relief while simultaneously preventing external flames from entering the tank. It is the ideal choice for facilities handling flammable liquids where space is limited and maximum explosion protection is required.
Producdt Description:
ZCPE-pilot operated breather valve with flame arrester is a bit different with breather valve ,first let the seat leakage closer to set point ,second full flow without overpresure ,to maintain the tank pressure balance, reduce safety energy-saving products medium volatile, but also the use of principles of vapor heat transfer, protect the respiratory valve parts is not easy to freeze, the breathing valve to ensure the normal work, equipped with fire retardant explosion-proof function.
Fire breathing valve produced by our company has simplified structure, ventilation volume, less leakage, corrosion resistance, insulationetc.. The valve adopts polytetrafluoroethylene material, has the advantages of low temperature resistant, anti frost. The electrostaticprotection device is provided with a respiratory valve, the valve and the tank to keep the same potential moment.

Q1: What is the benefit of having the flame element “inside” the breather valve?
A1: This integrated design saves significant installation space on the tank top and reduces costs by combining two essential safety devices—a breather valve and a flame arrester—into a single unit.
Q2: Can the internal flame element be cleaned or replaced?
A2: Yes. The ZCBV-IZ is designed for easy disassembly, allowing the flame element to be removed, inspected, and cleaned to maintain optimal flow and safety performance.
Q3: Does the internal element increase the pressure drop across the valve?
A3: Our engineers have optimized the internal matrix of the corrugated filter element to ensure minimal resistance while providing maximum flame quenching capability.
Q4: Is this valve suitable for corrosive chemical storage?
A4: Absolutely. We offer “Overall 304” or 316L stainless steel versions that provide excellent resistance to aggressive chemical vapors and saline environments.
Q5: What flange standards are compatible with the ZCBV-IZ?
A5: We support all major international standards, including ANSI, DIN, JIS, and GB, ensuring a perfect fit for your existing tank infrastructure.
