It ensures safe handling of liquids without mixing or pollution. 2. **Working Principle** This valve is controlled by compressed air and operates as a normally closed (NC) valve. It features two separate seals on the valve disc, with an internal leak cavity between them. In case of leakage, the product flows into the cavity and is directed away from the outlet, preventing cross-contamination. The cavity remains sealed during operation, ensuring no overflow and allowing for CIP (Clean-in-Place) cleaning. 3. **Materials** - **Steel Parts:** Stainless 304 / 316L - **Seals:** EPDM (standard), SILICON, FKM, HNBR (optional) 4. **Advantages** - Excellent resistance to acids, alkalis, and high temperatures - Low permanent compression deformation - Investment-forged valve plug for better durability than cast parts - Modern and stylish design aligned with international trends - Cost-effective and reliable performance 5. **Connection Types** - Welded - Clamped - Screw/Threaded - Flanged - Welded-Screw All connection types are manufactured to meet international standards such as DN11850, IDF, ISO, and SMS 3A for compatibility with imported equipment. 6. **Sizes Available** - **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 Types** - **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, pneumatic off - Normally Closed: Spring off, pneumatic on - Optional signal feedback sensor - Compact design, small size, high torque - Easy assembly and maintenance 9. **Technical Parameters** - **OD Range:** DN25–DN200, 1"–8" - **Anti-Pressure:** 10 Bar - **Compressed Air Supply:** Minimum 4 BAR, Maximum 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:** Air pipe equipped with R1/“ adapter - **Max Grain Size:** 0.11 mm - **Max Oil Content:** 0.08 ppm - **Dew Point:** ≤ 10°C - **Max Water Content:** 7.5 g/kg --- **Product Images** Sanitary Stainless Steel Proof Mixing Valve Sanitary Stainless Steel Proof Mixing Valve This product is ideal for hygienic environments where contamination must be avoided.
