Characteristics of food grade valves

Sanitary valves, also known as food-grade valves, are a type of fluid control equipment specifically used in industries with strict hygiene requirements, such as food, beverage, dairy, pharmaceutical and others. As the products of these industries are directly related to people's health and life safety, the sanitary standard requirements for valves are extremely high. The design, manufacture and installation of sanitary valves need to comply with the relevant health standards and norms to ensure the purity and safety of the fluid.

Features：
1. Excellent material: sanitary valves are usually made of stainless steel, aluminum alloy and other corrosion-resistant, easy-to-clean high-quality materials to adapt to high health standards and cleaning requirements.
2. Simple structure: the valve structure is simple, easy to disassemble and clean, to avoid dead ends and residues.
3. Surface treatment: the surface of the valve is polished, electrolyzed and other treatments, smooth and flawless, and not easy to breed bacteria.
4. Sealing performance: sanitary valve has good sealing performance, can effectively prevent fluid leakage and pollution.
5. Convenient operation: the valve is reasonably designed, easy to operate, and convenient for daily maintenance and cleaning.

Classification
According to the use and structure, sanitary valves can be divided into various types, such as globe valves, ball valves, butterfly valves, check valves and so on. Each type of valve has its own characteristics and is suitable for different fluid control scenarios.
Selection and installation
1. Selection principles: In the selection of sanitary valves, should be based on the nature of the fluid, working pressure, temperature and other factors for selection, while considering the valve's corrosion resistance, wear resistance, sealing and other factors.
2. Installation requirements: the installation of sanitary valves should be in line with relevant health standards and norms to ensure that the valve installation position, direction, height and so on in line with the design requirements. The installation process should avoid collision and damage to the valve should be installed after the sealing test and cleaning.

Maintenance
1. Regular cleaning: Regular cleaning of sanitary valves to remove dirt and residues on the valve surface to keep the valve clean and sanitary.
2. Inspection and maintenance: Regularly check the sealing performance of the valve, operational flexibility, etc., and find problems with timely repair or replacement.
3. Anti-corrosion measures: for easy to corrode valve parts, should take appropriate anti-corrosion measures, such as applying antirust agent, regular replacement of wearing parts, etc.

Sanitary valves as one of the key equipment in the food, beverage, dairy, pharmaceutical and other industries, its health standards and safety performance is critical. Understanding the general knowledge and selection of sanitary valves, installation, maintenance methods, help to ensure the purity and safety of the fluid, to protect people's health and life safety. At the same time, with the continuous progress of science and technology and health standards continue to improve, the design and manufacture of sanitary valves will continue to improve and innovate, to provide a strong guarantee for the development of the industry.
