Why Choose Pneumatic Sanitary Valves?

Pneumatic sanitary valves are electronically polished as standard, and the smooth surface ensures cleanliness with no areas of media accumulation and potential contamination.

Other valves are generally modeled according to the needs of use, mainly in the high temperature and high pressure working environment, long service life and flexible operation mode.

Materials

Sanitary valves can be made of 304SS, 304L or 316, 316L stainless steel. After production and processing, they have undergone special treatment, while other valves can be made of cast iron, cast steel, ductile iron, stainless steel, and a wider range of materials.
Because sanitary valves are used in pharmaceuticals, food, daily chemicals, etc., which have high sanitary requirements, these products are all edible or in direct contact with the human body, Sanitary grades are also used in environments with strict health regulations that require a zero-tolerance policy for physical and chemical hazards.

All sanitary valves must be sterilized in order to meet certain health standards. Non-hygienic valve manufacturers cannot produce such valves because all toxic components (such as lead) must be removed, which can lead to poisoning, cancer and even death. Therefore, most sanitary valves are made entirely of stainless steel.

However, ordinary valve materials such as steel, iron, copper and other materials cannot be satisfied. First of all, steel and iron are used as valves. If the humidity in the liquid or air is relatively high, they will corrode and rust, thereby polluting the product. The same is true for copper valves, and the patina is also a toxic substance, so it cannot be used as a sanitary valve.

Connection

Sanitary valves generally adopt the way of clamp quick installation connection. While the connection methods of industrial valves include flanged, thread, welding, etc.

COVNA pneumatic sanitary valve has the following advantages:

  • Seamless
  • Easy to clean
  • Smooth and polished surface
  • These properties allow the product to flow cleanly and remain sterile without the risk of bacterial growth or other forms of contamination.
