What Are The Characteristics And Types Of Sanitary Valves

Sanitary valves must ensure that they will not contaminate the materials flowing through them during operation. They have strict standards and requirements in terms of material selection, surface treatment, structural design, and cleaning and maintenance. So do you know what are the characteristics and types of sanitary valves?

Features of Sanitary Valve:
Material selection: Usually made of stainless steel (such as 316L), which has good corrosion resistance and biocompatibility.
Surface finish: The internal surface is finely polished to achieve a high finish, usually Ra≤0.8μm, to reduce bacterial growth and residue.
No dead angle design: The structural design of the valve should avoid dead angles to ensure that the fluid can be emptied and easy to clean.
Quick disassembly and assembly: The valve components should be easy to disassemble and assemble for easy cleaning and maintenance.
Sealing performance: Use sealing materials that meet sanitary standards, such as EPDM, PTFE, etc., to ensure no leakage and do not affect product quality.

Types of sanitary valves:
Sanitary ball valves: Both the ball and the valve seat are designed in a sanitary grade and are suitable for controlling flow.
Sanitary butterfly valve: The valve plate is disc-shaped, suitable for large-caliber and low-pressure drop occasions, and easy to operate.
Sanitary diaphragm valve: The flow of fluid is controlled by the up and down movement of the diaphragm, and it is suitable for media containing suspended matter.
Sanitary plug valve: The valve disc of the plug valve is cylindrical or conical, and the fluid is controlled by rotation.
Sanitary check valve: A valve that prevents fluid backflow, usually using a lifting or swinging structure.
Sanitary valves are valves designed to meet the hygiene requirements of food, beverage, pharmaceutical and bioengineering fields.
