Hygienic Stainless Steel Flanged Butterfly Valves
A hygienic stainless steel flanged butterfly valve is a high-precision flow control device designed for sterile environments, featuring a streamlined disc that rotates to open or close the fluid path. These valves are typically constructed from high-grade stainless steel such as 316L to ensure maximum corrosion resistance and compliance with sanitary standards in the food, beverage, and pharmaceutical industries.They are characterized by their "crevice-free" design, which prevents bacterial growth and allows for easy cleaning via CIP (Clean-in-Place) or manual disassembly.
Key Findings
* **Material Grades:** Primarily manufactured from AISI 304, 316, or 316L stainless steel for the body and disc to ensure durability and chemical resistance.
* **Pressure Ratings:** Common ratings include PN10, PN16, CL150, and JIS 5K/10K, with specific hygienic models rated from full vacuum up to 700 KPa (approx. 7 bar). [Stainless Steel Hygienic Valves]
* **Size Range:** Available in a wide variety of sizes, typically ranging from DN50 to DN3000 (2” to 40”) for industrial flanged types, though sanitary specific models often focus on 1/2" to 12".
* **Sealing Materials:** Seats are often made of Silicone, EPDM, or PTFE to handle different temperature ranges and chemical exposures.
* **Application Scope:** Extensively used in food processing, dairy, brewing, beverage production, and cosmetic manufacturing.
