**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 ensure precise control of fluid media in various industrial environments.
2. **Working Principle:**
The pneumatic stop valve converts the energy from compressed air into mechanical motion, which drives the stem to move axially. This movement controls the opening or closing of the pipe's outlet, allowing for directional changes or medium retention. The manual version is operated via a handle, serving the same purpose of controlling the direction or stopping the flow of the medium.
3. **Technical Data Sheet:**
- New-style sanitary stop/switch valves offer improved safety, clearance, durability, and aesthetics.
- A separate open support design isolates the pneumatic actuator from the valve body, enabling direct inspection of the shaft seal. This design also separates the gears from the product parts, preventing heat transfer from the valve body to the actuator.
- "NC" and "NO" functions can be switched instantly.
- Spherical valve bodies provide excellent fluidity and clearance.
- Material handling is more gentle and efficient.
- Standard valve body design allows for flexible and diverse joint styles.
- Metal stop mechanisms ensure long-lasting seal performance.
- Quick and convenient assembly and maintenance.
4. **Material:**
- Contact steel parts: Stainless Steel 304 or 316L
- Valve core seal options:
- Soft seals: EPDM (standard), SILICON, FDM, HNBR (optional)
- Metal seals available upon request
5. **Advantages:**
- Excellent resistance to acid, alkali, and high temperatures.
