Stainless Steel Sanitary Pneumatic Globe Valve Yj

**Specifications** Sanitary pneumatic (manual) globe valve / stop valve / gate valve HS Code: 8481804090 **TECHNICAL PARAMETERS** 1. **Application:** These valves are widely used in automation and control systems to regulate pressure, flow, level, temperature, and tank levels. They are ideal for applications where hygiene and precision are essential. 2. **Working Principle:** The pneumatic stop valve converts the energy from compressed air into mechanical movement, which drives the stem to move axially. This motion controls the position of the sealing components, allowing the valve to open or close, thus controlling the direction of the medium or keeping it in place. The manual version is operated by a hand lever, offering similar control functions. 3. **Technical Data Sheet:** I. New-style sanitary stop/switch valves offer enhanced safety, clearance, durability, and aesthetics. II. A separate support system isolates the pneumatic actuator from the valve body, allowing direct inspection of the shaft seal. This design prevents heat transfer from the valve body to the actuator. III. The "NC" and "NO" functions can be quickly switched. IV. Spherical valve bodies provide excellent fluidity and minimal resistance. V. The materials used are more gentle on the process media. VI. Standard valve body design offers flexible and diverse connection options. VII. A metal stop mechanism ensures long-lasting sealing performance. VIII. Quick and easy assembly and maintenance make these valves user-friendly. 4. **Material:** - Contact parts: Stainless steel 304 or 316L - Seal options: a) Soft seals: EPDM (standard), Silicon, FDM, HNBR (optional) b) Metal seals available upon request 5. **Advantages:** - Excellent resistance to acids, alkalis, and high temperatures with minimal permanent deformation. - Forged valve plugs offer better metallurgical structure than cast ones, with pressure durability up to 1.2 MPa. - Modern and elegant design that aligns with international trends. - Cost-effective alternative to imported products, ensuring reliable operation and reduced costs. 6. **Connection Types:** Welded, Clamped, Screw or Threaded, Flanged To ensure compatibility with imported equipment, all connection styles are designed according to international standards such as DN11850, IDF/ISO, SMS 3A. 7. **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 8. **Surface Treatment:** - Outer surface: Sandblasted, Ra ≤ 1.6 μm - Cast sub-light: Ra ≤ 0.6 μm - Inner surface: Polished, Ra ≤ 0.6 μm 9. **Operation Type:** - Manual: Lever or duck-billed handle - Pneumatic actuator: Stainless steel or plastic, with or without control box - Electric actuator: Single or double action 10. **Features of Pneumatic Actuator:** - Normally Open: Spring is open, air supply off - Normally Closed: Spring is closed, air supply on - Optional signal feedback inductive sensor - Compact design, small size, large torque - Simple and convenient installation 11. **Technical Parameters:** - OD Range: DN25 ~ DN200, 1" ~ 8" - Pressure Rating: 10 Bar - Compressed Air Supply: Min 4 BAR, Max 8 BAR - Pneumatic Actuator Torque: 40 Nm - Finishing Degree: - Cutting: Ra 1.5 ~ 3.2 μm - Polishing: Ra 0.4 ~ 0.8 μm 12. **Specifications of Sanitary Globe Valve:** 1. **Diameter of the Globe Valve:** a) Manual Sanitary Globe Valve: Available in various sizes to meet different application requirements.
