Sanitary Stainless Steel Proof Mixing Valve

**Product Description: Sanitary Stainless Steel Double Seat Mix-Proof Valve (Model YF)** **Quick Details** Model: YF Place of Origin: Wenzhou, China Standard: DIN 3A, SMS, ISO, IDF Structure: MIPROOF Pressure: Normal Pressure Power: Pneumatic / Manual Material: SS304, SS316L Temperature of Media: Medium Temperature Media: Water or Other Liquids Model Number: YF 1"–4" Brand Name: YUY **Packaging & Delivery** Packaging Detail: Inner Poly Bag Delivery Detail: 2–3 days after payment **Specifications** HS Code: 8481804090 **Technical Parameters** 1. **Application** The YF series double seat mix-proof valve is designed for use in brewing, dairy, and beverage industries to prevent product mixing and contamination. It ensures safe and clean transfer of liquids between pipelines and supports CIP (Clean-in-Place) cleaning. 2. **Working Principle** This pneumatic-controlled, normally closed (NC) valve features two separate sealing surfaces. During operation, a leak chamber is created between the two seals. In case of leakage, the product flows into the chamber and is safely drained away, preventing cross-contamination. The leak chamber remains sealed during normal operation, ensuring no overflow occurs. 3. **Material** - Steel Parts: Stainless 304, 316L - Sealing: EPDM (standard), SILICON, FKM, HNBR (optional) 4. **Advantages** - Excellent resistance to acids, alkalis, and high temperatures - Low permanent compression deformation - Investment-forged valve plug with superior metallographic structure compared to cast parts - Modern, international-style design - Cost-effective and reliable performance 5. **Connection Types** Welded, Clamped, Screw/Threaded, Flanged, Welded-Screw All connections are manufactured to meet international standards such as DN11850, IDF, ISO, SMS, and 3A for compatibility with imported equipment. 6. **Sizes** - DIN: DN15, DN20, DN25, DN32, DN40, DN50, DN65, DN80, DN100 - 3A: 3/4", 1", 1 1/2", 2", 2 1/2", 3", 4" - SMS: 19, 25, 32, 38, 51, 63, 76, 89, 102 - ISO: 19, 25, 32, 38, 51, 63, 76, 89, 102 7. **Operation Type** - Manual: Lever or Duck-Billed - Pneumatic Actuator: Stainless Steel or Plastic with or without Control Box - Electric Actuator: Single or Double Action 8. **Pneumatic Actuator Features** - Normally Open: Spring open, air off - Normally Closed: Spring off, air on - Optional signal feedback sensor - Compact design, small size, large torque - Easy and convenient assembly 9. **Technical Parameters** - Operating Range: DN25–DN200, 1"–8" - Anti-Pressure: 10 Bar - Compressed Air Supply: Min 4 BAR, Max 8 BAR - Pneumatic Actuator Torque: 40 Nm - Surface Finish: - Cutting: Ra 1.5–3.2 µm - Polishing: Ra 0.4–0.8 µm 10. **Compressed Air Quality Requirements** - Air Joint: Equipped with R1/4" adapter - Max Grain Size: 0.11 mm - Max Oil Content: 0.08 ppm - Dew Point: ≤ 10°C - Max Water Content: 7.5 g/kg **Images** Sanitary Stainless Steel Proof Mixing Valve Sanitary Stainless Steel Proof Mixing Valve This valve is ideal for hygienic environments where cleanliness and safety are critical.
