Breathing valves are ventilation devices installed on fixed storage tanks in petrochemical plants to prevent damage to the tanks due to overpressure or vacuum, and to prevent the entry of external flames and reduce the evaporation loss of the liquid inside the tank. According to the national "Code for Fire Protection Design of Petrochemical Plants" GB50160, "Fixed dome tanks for Class A and B liquids should be equipped with flame arrestors and breathing valves." To meet this requirement, our factory has developed a complete series of all-weather (fireproof) breathing valves.
They feature a scientific and novel design, a complete range of specifications and models, a compact structure, light weight, large ventilation capacity, and low leakage. The product structures include breathing type, single exhalation type, single inhalation type, different diameter type, and jacket type (refer to the SX series breathing valves for details). All structural forms can be equipped with flame arrestors and the required connection tubes at the exhalation and inhalation ends. At the same time, different materials are used to manufacture the valves for storage tanks containing different media such as oil, chemicals, and food, fully meeting the process requirements of various storage and transportation systems.
High-Performance Industrial Breather Valves
Safeguarding atmospheric storage tanks against dangerous pressure fluctuations requires a reliable breather valve. This component is essential for operational safety and environmental protection. Zhejiang Naibang Valves Co., Ltd. (NIPO) is a premier manufacturer and supplier of these high-performance industrial solutions. Our engineered products provide critical pressure and vacuum relief. They ensure storage tanks safely equalize during filling, emptying, or thermal changes. This prevents structural damage and hazardous emissions.
Types of Breather Valves We Manufacture
To meet the diverse demands of the petroleum, chemical, and energy sectors, NIPO manufactures a comprehensive range of pressure relief solutions. By categorizing our specific offerings, we help procurement managers and engineers quickly navigate to the exact unit required for their unique tank configurations.
All-Weather Breather Valves
Our all-weather breather valves are specifically designed to deliver consistent performance across diverse environmental conditions. These units protect standard atmospheric tanks from extreme pressure fluctuations. They also effectively prevent moisture ingress and contamination. Built to withstand harsh outdoor elements, they ensure continuous, reliable tank equalization year-round.
Explosion-Proof Breather Valves
For facilities handling highly volatile media, our explosion-proof models offer an essential layer of security. Often integrated as a flame retardant breather valve, these units feature advanced flame-arresting capabilities. This design prevents flame propagation into the tank. They are engineered to ensure maximum safety and compliance in hazardous chemical and petroleum applications.
Technical Specifications & Material Options
Industrial buyers and engineers require precise technical data to ensure system compatibility. NIPO provides comprehensive technical support for every breather valve model. This includes downloadable CAD drawings and detailed pressure rating charts. We offer a diverse selection of premium materials tailored to handle different media. These range from standard fuels to highly corrosive chemicals.
| Material Options | Best Suited For | Typical Industrial Applications |
