The ZCBV-IV Breathing Valve With Piping Connection is a specialized pressure vacuum relief valve (PVRV) engineered for modern storage tank management. Unlike standard atmospheric vent valves, the ZCBV-IV features a dedicated piping connection outlet. This allows the valve to be seamlessly integrated into vapor recovery systems (VRS) or closed-loop piping, preventing the direct release of volatile organic compounds (VOCs) into the atmosphere while maintaining critical tank pressure balance.
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: Why do I need a “Piping Connection” on my breathing valve?
A1: The piping connection allows you to collect and redirect vapors to a recovery unit (VRU) or a flare system, which is essential for reducing VOC emissions and complying with environmental laws.
Q2: Is the ZCBV-IV compatible with standard vapor recovery systems?
A2: Yes. The valve is designed with standard flange interfaces (ANSI, DIN, JIS, GB) to ensure seamless integration into almost any industrial vapor collection piping.
Q3: Can this valve handle corrosive chemical vapors?
A3: Absolutely. For aggressive media, we recommend our SS316L stainless steel configuration, which provides superior resistance to chemical corrosion.
Q4: Does the piping connection affect the pressure relief settings?
A4: Our engineers calibrate each ZCBV-IV to operate accurately at your specified set pressures, ensuring the added piping backpressure is accounted for in the safety design.
Q5: Can I add an internal flame element to this specific model?
A5: While the ZCBV-IV focuses on piping connection, we offer related models like the ZCBV-IVZ that integrate inside flame elements for added explosion protection within the same compact footprint.
