Hygienic butterfly valves are quarter-turn shut-off valves used for isolation and flow regulation in sanitary pipeline systems. They offer a compact design, low flow resistance, and various end connections to suit the food, beverage, and pharmaceutical industries.
Key Features and Materials
Materials: The body and disc are typically manufactured from high-grade 316L stainless steel for superior corrosion resistance. Seals (liners) are available in food-grade elastomers like EPDM (standard for steam and hot water), Viton®, or Silicone, which conform to FDA requirements.
Design: They feature a streamlined, low-resistance design that allows easy passage of low- to medium-viscosity liquids, including those with solid particles. The surface finish is highly polished (often to Ra 0.8μm or less) to minimize product retention and facilitate cleaning.
Operation:
Manual: Available with various handles, including two-position pull handles or multi-position notched levers, which allow for throttling of flow.
Automated: Can be fitted with single or double-acting pneumatic actuators for remote on/off control, often with optional intelligent control units for feedback.
Pressure & Temperature: Typically rated for a maximum pressure of 10 Bar and a temperature range of around -10°C to +120°C with EPDM seals.
Available End Connections
Hygienic butterfly valves are highly modular and can be customized with various end connections to integrate with different international standards:
Plain Weld Ends: For permanent installation into pipework.
