In the food and beverage industry, valves are used to control, regulate, divert, and stop the flow of liquids, gases, steam, and semi-solid products while maintaining hygiene and sanitary standards. Most food-grade valves are made from SS304 or SS316L stainless steel with polished internal surfaces and comply with FDA, 3-A, EHEDG, and CIP/SIP cleaning standards.

Selection Criteria for Food Grade Valves

Choose valves based on:

• Product viscosity

• Cleaning method (CIP/SIP)

• Pressure & temperature

• Automation requirement

• Corrosion resistance

• Hygienic certifications

Sanitary valves in food plants are generally polished internally, dead-leg free, and designed for easy sterilization to avoid bacterial growth.
