无菌罐安全呼吸阀

 

Aseptic tank safety breathing valve

Sanitary storage tanks are often used in food fermentation and other industries. In order to prevent the invasion of microorganisms in the atmosphere, sanitary storage tanks are often protected by positive pressure clean air to prevent non-clean air from outside the tank from entering the tank. At present, most of the sanitary storage tanks are thin-walled structures, that is, non-pressurized containers, which can only withstand small positive pressure and negative pressure, so it is difficult to accurately adjust the general spring-loaded safety valve.

Body and material contact part: AISI 304 or AISI 316L
Positive pressure part: gravity type, 304 stainless steel counterweight
Negative pressure part: gravity type, 316L spool weight
Surface treatment: sandblasting
Sealing material: EPDM (EPDM)
Optional: silicone rubber (Q) and ternary fluorine rubber (FKM)

Working temperature: 4-95 ℃
Positive pressure take-off: 0.3-0.4bar (adjustable)
Negative pressure take-off: 100-200mm water column
Specifications: DN65 ~ DN350
