Sanitary Ball Valve Implementation Standards
A Sanitary Ball Valve is a type of valve used to control fluid flow and is widely used in the food, pharmaceutical, and chemical industries. To ensure fluid safety and hygienic requirements, sanitary stainless steel ball valves must meet certain implementation standards.
The implementation standards for Sanitary Ball Valve mainly include the following aspects:
1. Design and Manufacturing Standards:
The design and manufacturing of Sanitary Ball Valve must comply with relevant national and industry standards. National standards include the "General Technical Conditions for Stainless Steel Ball Valves" and the "General Rules for Marking, Packaging, Transportation, Storage, and Quality Assurance of Stainless Steel Ball Valves." Industry standards include standards for the food, pharmaceutical, and chemical industries.
2. Structure and Material Standards:
The structure and materials of Sanitary Ball Valve must comply with relevant standards. For example, the sealing surface between the ball and the valve seat must be made of a sanitary elastic material, such as silicone or polytetrafluoroethylene. The valve body and bonnet must be made of stainless steel, such as 304 or 316L stainless steel, to ensure surface smoothness and rust resistance.
3. Sanitary Requirements:
Sanitary Ball Valve must meet relevant sanitary requirements, such as internal valve finish, connection method requirements, and cleaning requirements. Internal valve finish requirements are typically measured using surface roughness indicators, such as the Ra value. Connection method requirements primarily refer to the connection method between the valve and the pipe, with common examples including flange, threaded, and wafer connections. Cleaning requirements include internal valve flushing and disinfection.
4. Testing and Verification Standards:
The testing and verification of Sanitary Ball Valve must comply with relevant standards. Common testing methods include visual inspection, dimensional inspection, strength testing, and sealing tests. Verification methods include calibration and verification records. The purpose of these tests and verifications is to ensure that sanitary stainless steel ball valves meet the expected performance and quality requirements during use.
In summary, the implementation standards for Sanitary Ball Valve are to ensure that their design, manufacturing, structure, materials, sanitary requirements, testing, and verification meet relevant national and industry standards. By implementing the requirements of the standard, the safety and hygiene of sanitary stainless steel ball valves can be ensured, providing users with reliable fluid control solutions.
