Stainless Steel Sanitary Flange-Type Butterfly Valve and Check Valve Combination (Manual Lever-Operated)
Product Overview
The sanitary flanged butterfly valve is a quick-release valve manufactured from stainless steel (typically 304 or 316L grade) and installed into piping systems using flanged connections. It performs the functions of opening, regulating, and closing the flow of media through the rotation of a butterfly disc; it features a compact structure, effortless operation, and excellent sealing performance.
Key Features
1. Material Advantages
304/316L Stainless Steel: Corrosion-resistant, high-temperature resistant, and compliant with food-grade sanitary standards.
316L Low-Carbon Material: Minimizes carbide precipitation, enhancing weldability and corrosion resistance.
2. Sanitary Design
Polished Inner Surface: Ra ≤ 0.8μm; smooth and free of dead spaces, preventing media residue accumulation and bacterial growth.
Dead-Space-Free Design: Smooth internal flow channels within the valve body ensure unimpeded media flow.
International Standard Compliance: Meets the requirements of international sanitary standards such as 3A, FDA, and EHEDG.
3. Structural Features
Flange Connection: Standardized flange interfaces ensure easy installation and reliable sealing.
Quick-Dismantle Structure: Facilitates easy disassembly for cleaning and maintenance, meeting CIP/SIP (Clean-in-Place/Sterilize-in-Place) requirements.
Double Eccentric Design: Reduces wear on the sealing ring, thereby extending service life.
4. Sealing Performance
High-Quality Sealing Rings: Utilizes food-grade silicone, fluororubber, or EPDM materials.
Zero-Leakage Sealing: Features a double-layer sealing structure to ensure zero leakage when the valve is closed.
Temperature Range: Suitable for operating environments ranging from -10°C to +150°C.
