Product Description
Introducing the Stainless Steel Sanitary Flanged Butterfly Valve, an expertly engineered flow control solution crafted to meet the precise hygiene standards required by industries such as food and beverage, pharmaceutical, bioprocessing, and cosmetic manufacturing. This advanced valve is meticulously constructed from high-grade stainless steel and showcases a distinctive design and impeccable surface finish to adhere to the most rigorous standards of sterility, cleanability, and safeguarding against product contamination.
Basic Design:
The valve comprises a robust body, an efficient disc (vane), a sturdy stem, and reliable sealing elements. Its disc is seamlessly rotated approximately 90 degrees via the stem to easily open or close the flow path.
Key Materials:
Body/Disc/Stem: Crafted from superior 304, 316, or 316L stainless steel (offering outstanding corrosion resistance and non-toxicity).
Seals: Engineered from FDA-approved materials such as Silicone (SI), EPDM, or PTFE (Teflon) to ensure exceptional compatibility with process media and the resilience to handle cleaning-in-place (CIP) and sterilization-in-place (SIP) operations.
Connection Type:
Designed with Flanged Ends. This design ensures a firm and leak-proof connection that facilitates straightforward assembly and disassembly for maintenance and thorough cleaning.
Bore Size (DN):
Available in a diverse range, typically from DN25 (1") to DN200 (8") or larger, to accommodate a variety of pipeline flow requirements.
Pressure Rating (PN):
Standardized ratings include PN0.6, PN1.0, and PN1.6 MPa.
Surface Finish:
All wetted surfaces undergo mechanical or electropolishing to achieve a highly smooth, mirror-like finish (which is typically Ra ≤ 0.8 µm or superior). This process eliminates microscopic crevices where bacteria could hide, prevents material adhesion, and allows for effortless and thorough cleaning and sterilization.
Core Features:
1. Hygienic, Dead-Space-Free Design: The smooth, contoured flow path effectively prevents product build-up and ensures complete drainability.
2. Compliant with Sanitary Standards: Manufactured to meet international sanitary criteria, including 3-A, FDA, EHEDG, and GMP.
3. Excellent Sealability: Top-notch seals guarantee dependable bubble-tight shut-off in both directions of flow.
4. Ease of Operation: Effortless 90° operation requiring minimal torque. It is adaptable and can be fitted with Available Actuation Options: Choose from manual levers, pneumatic actuators, or electric actuators for seamless automation.
5. Durable & Effortless Maintenance: Its simple construction allows for hassle-free disassembly, and the replaceable seals ensure a long-lasting service life.
Temperature Range:
Temperature capabilities vary based on the seal material used:
- EPDM: Suitable for conditions up to approximately 120°C - 150°C.
- Silicone (SI): Offers resilience up to around 150°C - 200°C.
- PTFE: Handles temperatures up to approximately 200°C.
Primary Applications:
Food & Beverage Industry: Ideal for sectors like dairy, brewing, sauces, and meat processing,
Pharmaceutical Industry: Perfect for API production and sterile solutions,
Biotechnology:Suitable for advanced applications, Cosmetics:and any process piping system demanding high standards of hygiene and purity.
Innovative Working Principle:
The operational magic unfolds as the handle rotates, translating into the valve shaft's movement, which drives the valve disc to pivot. When the disc aligns parallel with the pipeline axis, the valve assumes an open state, allowing fluid to traverse effortlessly. Conversely, when the disc turns perpendicular to the pipeline, it closes the valve, halting fluid flow, thus achieving precise on-off control and expert flow regulation within the system.
