Ball, Butterfly and Seat: Which Valve Does What?
There are some key differences between a hygienic seat valve and a butterfly valve. Here’s what you need to know:
Hygienic Ball Valves
These use a spherical closure element with a full-bore passage for quick isolation and tight shut-off. Their quarter-turn operation and minimal pressure drop make them well-suited to viscous fluids and media containing particulates.
Hygienic Butterfly Valves
These applications control flow using a rotating disc and are valued for their compact, lightweight design. Hygienic butterfly valves offer rapid operation and are a cost-effective choice for on/off control in high-volume sanitary lines.
Hygienic Seat Valves
Using a pneumatically actuated plug to seal against a contoured seat, hygienic seat valves provide precise shut-off and flow diversion. Seat valves are commonly specified in dairy, beverage, and pharmaceutical processing, where a drainable, cleanable valve design is critical.
Benefits of Hygienic Valves
Hygienic valves offer several advantages over standard industrial designs. Polished stainless steel construction resists corrosion and prevents residue from accumulating on internal surfaces, supporting effective CIP and SIP processes. Smooth, self-draining profiles reduce the risk of bacterial harbourage, while FDA- and 3-A-compliant materials ensure suitability for direct contact with food, beverages, and pharmaceutical products. Many designs are compact and easy to automate with pneumatic actuators and process control systems.
Where Hygienic Valves Are Used
Hygienic valves are widely specified across industries where contamination control and product purity are non-negotiable, including:
- Food and beverage processing
- Dairy and brewing
- Pharmaceutical and biotechnology manufacturing
- Cosmetics and personal care production
- Water treatment and utilities
- Data Centres
