In September 2024, a new policy was announced to promote the comprehensive renovation of tank breathing valves in Nanjing Jiangbei New Area, achieving an annual reduction of over 2000 tons of VOCs emissions.
The Jiangbei New Area New Material Science and Technology Park has a total of 982 organic material storage tanks and 1472 tank breathing valves, accounting for 66% of the tank breathing valves in Nanjing. Zhou Jun, Deputy Director of the Science and Technology Park Supervision Bureau of Nanjing Jiangbei New Area Ecological Environment and Water Affairs Bureau, stated that ordinary breathing valves and emergency relief valves can no longer meet the latest national safety and environmental protection requirements. The low leakage breathing valve, with its precise sealing structure and advanced control mechanism, ensures rapid response to pressure changes inside the storage tank, ensuring safe operation of the tank. At the same time, its superior sealing can reduce medium emissions and reduce the leakage of ordinary breathing valves from “two swimming pools” to “one water cup”; By reducing dielectric loss, good economic benefits can also be achieved.

Addressing the pain points of ‘dual valves’ with diverse products that meet the latest requirements
Storage tanks are major emitters of VOCs, and one of the root causes is the problem of “continuous discharge” and “continuous leakage” of breathing valves and emergency relief valves. ”On January 14, 2025, Zhang Yan, Chairman of Nanjing Prutaige Safety Equipment Engineering Co., Ltd. (hereinafter referred to as “Prutaige”), stated in an exclusive interview with China Industry News. Prutaige environmental protection technology solves the pain point of “dual valves”, improves the sealing of storage tanks, and solves the problem of unorganized VOCs emissions from storage tanks from the source. The State Council’s “Action Plan for Continuous Improvement of Air Quality” (Guofa [2023] No. 24) proposes to encourage the use of low leakage breathing valves and emergency pressure relief valves in storage tanks. The country has made low leakage breathing valve technology an important part of the action plan for continuous improvement of air quality, which is a great encouragement for Prutek and myself, “Zhang Yan said emotionally.” As people become increasingly aware of the importance of using low leakage breathing valves and emergency relief valves, it means that more new quality productivity has become the driving force for green transformation
We tailor our products to different storage tanks, media, and operating conditions for enterprises in Jiangbei New Area, providing over ten different types of products. For example, for media that are prone to crystallization and polymerization, we offer self operated anti crystallization and anti polymerization integrated flame retardant breathing valves. For heavy oil tanks in refining enterprises, we provide anti solidification integrated flame retardant breathing valves. “Zhang Yan explained,” This is also one of the reasons why Prutaige can lead the industry, because we can provide different selection schemes according to different usage scenarios
Pruitt ® Ultra low leakage breathing valve series products
It is understood that in the current breathing valve industry, it is often the manufacturer’s wheel hammer, and the phenomenon of “one breathing valve, one structure travels all over the world” is not uncommon. But such a product strategy is not feasible in the view of Prutaige. Product diversity is a concentrated reflection of a company’s strong vitality, “said Zhang Yan.
