Valves
Valves for food, health, and pharmaceutical industries
An extensive range of hygienic valves
for the food and pharmaceutical industries
Coperion and its technology brands offer one of the most extensive and advanced ranges of valves for the food industry, designed to meet the demanding requirements of food, pharmaceutical, and nutraceutical processing.
These hygienic valves feature robust construction, smooth product-contact surfaces, and easy-clean configurations that support strict safety and contamination-control standards. In addition, they are compatible with plastics, chemicals, and mineral processing applications, making them suitable for industries beyond food and pharma.
These valves are also compatible with plastics, chemicals, and mineral processing applications. For more details, please visit the valve page on Coperion performance material website.
Conveying valves for food industry
These valves are primarily used to control pneumatic conveying flows in food, pharmaceutical, and nutraceutical processes. They also ensure smooth product transport while maintaining hygiene and minimizing contamination risks.
Butterfly
valves
Butterfly valves use a flat, rotating disc mounted on a central shaft to open or close flow, offering quick, reliable shut-off and basic throttling. Commonly, they are used in food processing for liquids, slurries, and air conveying. Because of their lightweight design, they are easy to clean and available in sanitary construction.
Diverter
valves
Diverter valves are flow-routing valves that direct dry bulk materials, such as powders, grains, or pellets from a single source line to two or more destination lines. Using an internal flap, rotor, or sliding blade, they switch paths efficiently. They’re essential for distributing product to different mixers, packaging lines, or storage bins while maintaining hygienic standards.
Rotary
valves
Rotary valves use a rotating, pocketed rotor inside a tight housing to meter dry bulk materials (e.g., flour, sugar, starch, grains) from one process step to another while maintaining an airlock between zones. They are ideal for feeding product steadily into pneumatic conveying lines, controlling discharge from hoppers or cyclones, and preventing air pressure loss.
Gravity flow control valves for food industry
Valves in this category control the free-fall flow of materials, typically under silos or hoppers. They ensure smooth, safe, and hygienic material handling in high-capacity systems.
Disc gate
valves
Disc gate valves use a flat, sliding plate that opens or fully blocks the flow of dry bulk materials. This simple, reliable shut-off minimizes product shear, making them ideal for isolating hoppers, bins, and feeders.
Iris diaphragm
valves
Iris diaphragm valves are circular valves made of multiple overlapping “leaves” that open and close like a camera aperture, creating a perfectly concentric, variable opening. They are ideal for gently regulating the flow of powders, grains, pellets, and other fragile bulk solids.
Slide gate
valves
Slide gate valves provide controlled isolation of hoppers and feeders. Their sliding plate mechanism ensures precise flow control with minimal product stress, which makes them suitable for high-capacity dry bulk applications.
