Specifications:
Sanitary Pneumatic (Manual) Globe Valve / Stop Valve / Gate Valve
HS Code: 8481804090
Technical Parameters:
1. Application:
The valves are widely used in automation and control systems to regulate pressure, flow, level, temperature, and tank levels. They are ideal for use in the food, pharmaceutical, and biotechnology industries where hygiene and safety are critical.
2. Working Principle:
The pneumatic stop valve converts compressed air energy into mechanical movement, which drives the stem to move axially. This motion controls the sealing components, allowing the valve to open or close, thus regulating the direction of the medium or keeping it stationary. The manual version is operated by a handle, serving the same purpose of controlling the flow or stopping the medium.
3. Technical Features:
I. New-style sanitary stop/switch valves offer improved safety, clearance, durability, and aesthetics.
II. A dedicated support system separates the pneumatic actuator from the valve body, allowing direct inspection of the shaft seal. This design isolates the gear mechanism from the product parts, preventing heat transfer from the valve body to the actuator.
III. The "NC" and "NO" functions can be switched instantly.
IV. The spherical valve body ensures excellent fluidity and smooth passage.
V. The material handling process is gentler, reducing wear and tear.
VI. Standardized valve body design offers flexible and varied connection styles.
VII. A metal stop mechanism ensures long-lasting seal performance.
VIII. Quick and convenient assembly and maintenance make this valve user-friendly.
4. Material:
Material contact parts: Stainless Steel 304 or 316L
Valve seat 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 compression deformation. Forged valve plugs provide better structural integrity than cast ones and can withstand pressures below 1.2 MPa. The modern design follows international fashion trends, and the cost-effective solution offers reliable performance while replacing imported alternatives.
6. Connection Types:
Welded, Clamped, Screw or Threaded, Flanged. To ensure compatibility with imported equipment, all connections are designed to meet international standards such as DN11850, IDF/ISO, SMS 3A.
7. Sizes Available:
- DIN: DN15, DN20, DN25, DN32, DN40, DN50, DN65, DN80, DN100
