Breathing valve is a kind of valve which can not only ensure that the storage tank space is isolated from the atmosphere within a certain pressure range, but also communicate with the atmosphere (breathing) when the pressure range is higher or lower. Its function is to maintain the storage tank pressure balance of safety and energy-saving products.

The aseptic technology of biological fermentation puts forward strict requirements for positive and negative pressure breathing valve. However, the domestic positive and negative pressure valves in the market can not meet the requirements of biological fermentation aseptic technology, and need to be used with sterile filters and other equipment. However, the imported positive and negative pressure valves have high price, long delivery period and high subsequent maintenance cost.

In view of these problems existing in the market, Shanghai Yuan'an developed positive and negative pressure sterile breathing valve through independent directional research and development, and organized technical research and development. The technology obtained the national invention patent in 2016.

Advantages and features:

Shanghai Yuan'an endows the positive and negative pressure sterile breathing valve with new contents in terms of function: it has the advantages of self cleaning device, self discharging function, and self sterile air inflation protection device. With the heavy hammer pressure relief structure, the tank body is more stable, safe and reliable under the condition of alternating cold and hot impact. According to the customer's needs, the negative pressure valve can be opened pneumatically and the position feedback can be selected according to different processes In order to ensure the safe operation of the sterile valve and protect the tank body, the positive pressure valve is forced to open position feedback, and the heating and insulation device is installed in the low area where freezing is easy to occur below zero.

Shanghai Yuan'an aseptic breathing valve has been widely used in the fermentation industry, realizing domestic substitution for import, and breaking through the foreign technical barriers of positive and negative pressure sterile breathing valves for tanks.

Users are welcome to come to our company and put forward suggestions to promote the further research of sterile breathing valve.
