Sanitary valves play an important role in the beer industry. such as sanitary safety valve, which plays a safety protection role in the system. When the system pressure exceeds the specified value, sanitary safety valve is opened, and a part of the gas / fluid in the system is discharged outside the atmosphere / pipeline, so that the system pressure does not exceed the allowable value, thus ensuring that the system does not have an accident due to excessive pressure. Applicable to the recovery and exhaust of CO2 gas in fermenter and maintain stable pressure in tank. Therefore, the health-grade safety valve plays a key role in the quality and taste of beer.
sanitary valve body are all stainless steel, all contact parts with the medium for mirror polishing, polishing roughness to meet the sanitary standard, meet the sanitary standard of valve assembly. Sanitary valves have special rules and requirements for sealing materials, seat sealing surface must use non-toxic material.
Mechanical seal requirements for sanitary valves
1. Meets GMP requirements
2. Surface finish above 1.6um
3. Contact surfaces can be cleaned in situ and disinfected in situ
4. Too smooth, no material, no residue
5. Has a structure outside the sealing surface to prevent stringing.
