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.

Common Questions About Valves with Inside Flame Elements
Q1: What is the main advantage of the ZCBV-IVZ over standard breather valves?
A1: The ZCBV-IVZ includes an internal flame element, meaning it provides both pressure relief and explosion protection in one unit, saving space and reducing the cost of purchasing separate flame arresters.
Q2: Can the internal elements be cleaned easily?
A2: Yes. The ZCBV-IVZ is designed for easy disassembly, allowing for the inspection and cleaning of both the valve discs and the flame arrester element to maintain optimal safety performance.
Q3: Which gas groups is the internal flame arrester compatible with?
A3: Standard units are typically designed for Group IIA and IIB3 gases. However, custom flame elements can be manufactured for more volatile IIC (Hydrogen) applications.
Q4: Is this valve suitable for chemical storage tanks?
A4: Absolutely. We offer “Overall 304” or 316L stainless steel models that provide excellent resistance to aggressive chemical vapors and saline coastal environments.
Q5: What flange standards are supported for installation?
A5: Our ZCBV-IVZ valves are manufactured to integrate with all major global standards, including ANSI, DIN, JIS, and GB, ensuring a perfect fit for your existing tank setup.
