Hygienic-grade valves, also known as food-grade valves, are specialized fluid control equipment used in industries with strict hygiene requirements such as food, beverages, dairy products, and pharmaceuticals. As products in these industries directly affect people's health and safety, the hygiene standards for valves are exceptionally high. The design, manufacturing, and installation of hygienic grade valves must comply with relevant hygiene standards and specifications to ensure the purity and safety of fluids.
 
Features:
 
1. Superior Materials: Hygienic grade valves are typically made from high-quality materials such as stainless steel and aluminum alloys, which are corrosion-resistant and easy to clean, meeting high hygiene standards and cleaning requirements.
 
2. Simple Structure: Valves have a simple structure, making them easy to disassemble and clean, avoiding dead corners and residue.
 
3. Surface Treatment: Valve surfaces undergo polishing, electrolysis, and other treatments, ensuring smoothness and flawlessness, and preventing bacterial growth.
 
4. Sealing Performance: Hygienic grade valves have excellent sealing performance, effectively preventing fluid leakage and contamination.
 
5. Convenient Operation: Valves are designed for easy operation, facilitating daily maintenance and cleaning.
 
Classification:
According to usage and structure, hygienic grade valves can be classified into various types such as globe valves, ball valves, butterfly valves, and check valves. Each type has its own characteristics, suitable for different fluid control scenarios.
 
Selection and Installation:
 
1. Selection Principles: When selecting hygienic grade valves, factors such as fluid properties, operating pressure, and temperature should be considered, along with corrosion resistance, wear resistance, and sealing performance.
 
2. Installation Requirements: Installation of hygienic grade valves should comply with relevant hygiene standards and specifications, ensuring that the valve's installation position, direction, and height meet design requirements. During installation, care should be taken to avoid valve collision and damage, followed by sealing tests and cleaning.
 
Maintenance:
 
1. Regular Cleaning: Regular cleaning of hygienic grade valves to remove dirt and residues from the valve surface, maintaining cleanliness and hygiene.
 
2. Inspection and Maintenance: Regular inspection of valve sealing performance, operational flexibility, etc., to identify issues for timely repair or replacement.
 
3. Anti-corrosion Measures: Appropriate anti-corrosion measures should be taken for susceptible valve components, such as applying rust inhibitors or regularly replacing vulnerable parts.
 
As one of the key equipment in industries such as food, beverages, dairy products, and pharmaceuticals, the hygiene standards and safety performance of hygienic grade valves are crucial. Understanding the knowledge of hygienic grade valves and their selection, installation, and maintenance methods helps ensure the purity and safety of fluids, safeguarding people's health and safety. Additionally, with continuous technological advancements and improvements in hygiene standards, the design and manufacturing of hygienic grade valves will continue to evolve and innovate, providing strong support for industry development.
