Sanitary Check Valve needs to be cleaned and disinfected regularly. This is a key step to ensure that it meets hygiene standards, prevents bacterial growth and ensures product quality.

Regular cleaning
Cleaning frequency: Depending on the use environment and media, the cleaning frequency may vary. However, it is generally recommended to perform deep cleaning at least once a quarter.
Cleaning steps:
Close the valve: Before cleaning, make sure that the check valve is completely closed and disconnected from the system.
Disassemble the valve: According to the operating procedures, disassemble the valve into various components, especially the key parts such as the valve seat and valve disc.
Cleaning components: Use special cleaning agents or disinfectants, as well as tools such as soft cloth or brushes to thoroughly clean the various components of the valve to remove dirt, grease and residue on the surface.
Rinse and dry: After cleaning, rinse with clean water and wipe the components dry with non-woven cloth or clean nitrogen to ensure that there is no residual agent.
Reassemble: Reassemble the cleaned components into a complete check valve and check its sealing performance and operational flexibility.
Regular disinfection
Disinfection method: Disinfection can be done chemically or physically. Chemical disinfection usually uses chlorine-containing disinfectants, peracetic acid and other disinfectants to soak or wipe valve parts; physical disinfection can be done by high-temperature steam or ultraviolet irradiation.
Disinfection frequency: The disinfection frequency should be determined according to the use environment and the requirements of hygiene standards. In places with high hygiene requirements, such as the food, beverage and pharmaceutical industries, it is recommended to disinfect after each cleaning.
Precautions
Choose a suitable cleaning agent: The cleaning agent should be compatible with the valve material to avoid corrosion or damage to the valve.
Avoid cross contamination: During the cleaning and disinfection process, ensure that the tools and containers used are clean and free of contamination to avoid cross contamination.
Record and maintenance: Establish a cleaning and disinfection file for the check valve, record the time, method and results of each cleaning and disinfection, so as to track the hygiene status of the valve and predict future maintenance needs.

By regular cleaning and disinfection, the cleanliness and hygiene standards of the sanitary check valve can be ensured, thereby ensuring the stability of the production process and the safety of the product.
