In industrial fluid control systems, sanitary valves are key components that ensure the purity of the medium and the stability of system operation. The selection process requires comprehensive consideration of multiple technical parameters and operating conditions. Firstly, it is necessary to clarify the application scenarios of the valve, such as whether it is used in fields with extremely high cleanliness requirements such as food, pharmaceuticals, or biotechnology. Different industries have specific specifications for surface roughness, connection methods, and cleanability. Secondly, fluid characteristics are an important basis for determining the type of valve, including the viscosity, corrosiveness, temperature range, and presence of particulate matter of the medium. For high viscosity or easily crystallizable media, it is advisable to use diaphragm valves or ball valves with full bore design to reduce flow resistance and avoid residual accumulation. For systems that require frequent sterilization operations, priority should be given to valve structures that support SIP (online steam sterilization) and CIP (online cleaning) functions.

The operation mode of valves cannot be ignored, as manual, pneumatic, and electric actuators have their own applicable scenarios. Manual valves are suitable for low-frequency operation scenarios, while automated production lines rely more on pneumatic or electric control to achieve remote control and integrated management. In addition, the size and interface standards of the valve must match the pipeline system. Common connection forms include clamp type, threaded type, and welded type, among which clamp connection is widely used due to its convenient disassembly and reliable sealing. When selecting, it is also necessary to verify relevant certification qualifications, such as EHEDG, 3A, FDA, etc., which ensure that the product complies with international hygiene design standards. Finally, the manufacturer's technical support capabilities and the completeness of product documentation are also part of the evaluation, and detailed technical information helps with proper installation and post maintenance. In summary, scientific and reasonable selection not only improves system efficiency, but also effectively extends the service life of equipment.
