The flame arrestor breathing valve protects the storage tank by connecting it to the atmosphere, thereby preventing the tank from being damaged due to overpressure or overvacuum. PRV-A not only provides basic protection for storage tanks and operating systems, but also significantly reduces the loss of gas and steam inside the tanks, making important contributions to environmental protection and effectively saving economic costs at the same time.

Maintenance and repair
To ensure the safe application of the flame arrestor breathing valve, the corrugated flame arrestor layer should be removed and cleaned regularly within 3 to 6 months to guarantee that each hole on the flame arrestor layer is unobstructed and prevent blockage, ensuring safe and normal use. Regularly check whether the positive and negative valve discs work flexibly and whether the guide marks and the contact sealing surfaces of the valve discs are damaged. If any damage is found, they should be replaced immediately. When re-inspecting, maintaining and reinstalling, it is necessary to ensure that all the mating surfaces inside the valve fit tightly and that the valve disc can rise and fall flexibly. When a new valve is put into use, the flange protection cover should be removed before installation to clear the shockproof objects in the valve disc; otherwise, the breather valve will malfunction.
A flame retardant breather valve is a critical safety device engineered to protect industrial storage systems. It integrates a high-efficiency flame arrester with a precision breathing mechanism. Designed for volatile liquid storage, this equipment regulates tank pressure to minimize evaporation loss. It also provides a robust explosion defense mechanism.
By allowing tanks to safely breathe during thermal fluctuations, this integrated safety valve prevents structural damage. It protects against severe overpressure or vacuum conditions. Whether you manage chemical processing facilities or petroleum reserves, installing our reliable tank protection equipment ensures continuous operational safety and strict environmental compliance.
To meet the diverse demands of modern industrial applications, NIPO manufactures a comprehensive range of safety valves. We tailor these units to specific operational environments. Selecting the right configuration ensures maximum protection, regulatory compliance, and operational efficiency for your storage infrastructure.
Engineered for extreme ambient conditions, our all-weather models maintain reliable performance in temperatures from -29°C to +60°C. These units incorporate advanced anti-freezing components, such as PTFE valve seats and diaphragms. This prevents moisture from freezing and obstructing the mechanism, ensuring safe operation in harsh weather.
For facilities requiring highly accurate pressure control, pilot-operated units offer an ideal solution. These valves utilize a pilot control mechanism for precise tank pressure management. They open fully only when the exact set pressure is reached. This rapid response significantly reduces vapor emissions for high-value volatile media.
Comprehensive pipeline and storage tank safety often requires dual-action protection. Our integrated solutions combine robust pipeline flame arrestors with responsive breathing mechanisms. This design regulates internal pressure while actively quenching external ignition sources. It safeguards your entire infrastructure from catastrophic fires.
NIPO engineers every unit for technical superiority and long-lasting reliability in demanding environments. We manufacture our products to meet stringent international material standards. Whether you require a standard configuration or a customized stainless steel flame retardant breathing valve, our solutions deliver exceptional durability.
