Similarities and Differences between Hygienic and Aseptic Valves

Both Aseptic valves as well as hygienic valves are used in germs-sensitive environment e.g. pharmaceutical, cosmetic, bio-pharmaceutical, food and beverage, dairy or other kinds of high-purity industry/process. Both these valves have plenty in common depending upon their functionality and design, but yet they also have certain distinct differences.

Lets us first of all try to understand what we mean by aseptic and how can it be applied to valves or other sanitary replacements parts.

The term aseptic means free from contamination that are caused by harmful bacteria, microorganisms or viruses. All the highly germ-sensitive industries as mentioned above, where it is essential to maintain processes totally free from any contamination for safety reasons. Contamination in any food or beverage industry can greatly influence safety from microbiological quality of products, which can produce harmful effects on the consumers.

When aseptic concept is applied to valves it means they are designed with contamination free material. Aseptic valves can be designed with such materials and types of surface finishes, which make them very easy to clean. Also, they have components which are kept well protected from adverse surrounding environment with hermetical sealing. All the components that will be in contact with any process materials will not get contaminated due to environment.

Similarities between hygienic and aseptic valves

Hygienic and aseptic valves have number of similarities because of the following:

  • They utilize more or less the same materials
  • Both will feature on their surface’s smooth finishes.
  • Both these valves are designed in such a way that ensures no trapping of particles either from food or any other products, that would permit bacteria to get hide or assemble in them.
  • Both are used for similar applications where there is highly hygienic environment.
  • Both the valves use stainless steel, as this material will remain inert to both the cleaning materials and product used. Steel is non-toxic to process and corrosion-resistant too.

Differences between hygienic and aseptic valves

The major differences between hygienic and aseptic valves are as follows:

  • Their mode of operation and key purpose is different.

  • Major purpose of aseptic valve is to prevent contamination in the environment
  • Hygienic valve’s main purpose is to offer easy cleaning facility.
  • Components of any aseptic valves will never come in contact with any surrounding environment,
  • Hygienic valves can easily move in and move out from the process. It can be exposed to any surrounding atmosphere.
