Sanitary Diaphragm Valve

Sanitary Diaphragm Valve

The sanitary diaphragm valve features high cleanliness, no dead corners, easy cleaning, and corrosion resistance, with the diaphragm completely isolating the medium to prevent cross-contamination and meet GMP hygiene standards. Its main applications are in industries requiring strict fluid purity and sterility, including:

1. Pharmaceutical industry: Used for sterile processes such as liquid transfer, filtration, and purified water systems.
2. Food and beverage industry: Ideal for controlling liquids in dairy, juice, beer, and other production processes.
3. Biotechnology: Ensures sterility and purity of fluids in laboratory and production settings.
4. Cosmetic industry: Maintains the cleanliness of media in the production of creams, liquids, and other products.
