‌Different types of Sanitary Butterfly Valve have a wide range of applications, covering multiple industries with strict requirements on sanitary conditions.

‌Soft-sealed sanitary butterfly valve‌:

Mainly suitable for occasions with high reliability requirements and strict media requirements, such as sewage treatment plants, some chemical and metallurgical industries. In these environments, soft-sealed butterfly valves can provide good sealing performance and prevent the leakage of harmful substances.

In the food industry, soft-sealed sanitary butterfly valves are often used for process control and fluid transportation of media such as dairy products, beer, juice, and beverages to ensure the hygiene, safety, and stability of the production process.

‌Metal-sealed sanitary butterfly valve‌:

Applicable to high temperature, high pressure, and high sealing requirements, such as petroleum, chemical, power station and other industries. Metal-sealed butterfly valves can withstand high temperature and high pressure environments and maintain stable sealing performance.

In the pharmaceutical industry, metal-sealed sanitary butterfly valves are often used in raw material transportation, reactor control, filtration systems, drying systems, cooling systems, mixing systems, and cleaning systems to ensure the hygiene, safety, and system stability of the drug production process.

‌Electric or pneumatic sanitary butterfly valve‌:

Applicable to occasions that require remote operation, adjustment, and control, such as water systems and ventilation systems in commercial buildings, as well as purified water systems and sewage treatment systems in the pharmaceutical industry. These butterfly valves are remotely controlled and automatically operated through electric or pneumatic actuators, which improves production efficiency and convenience.

In addition, sanitary butterfly valves are also widely used in bioengineering, fine chemicals and other fields to meet the requirements of these industries for high hygiene performance and corrosion resistance.

In summary, the scope of application of different types of sanitary butterfly valves varies according to their structural characteristics, sealing performance and operation methods, but the common point is that they are all suitable for industries with strict requirements on sanitary conditions.
