Food Grade & Sanitary Air Blow Check Valves

0 products

Our food grade and sanitary air blow check valves are designed to comply with 3-A or NSF 51 standards, ensuring they are safe for use in dairy, food, and beverage processing. These valves efficiently remove residual substances from system lines during Clean-In-Place (CIP) processes, upholding sanitary conditions and safeguarding against corrosion. The mechanism involves air pressure displacing a spring-loaded rubber plug from its seat; once pressure ceases, the spring returns the plug to its position, effectively blocking any backflow into the line.
