**Product 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 and safe operation in various industrial environments.
2. **Working Principle:**
The pneumatic stop valve converts the energy from compressed air into mechanical movement, which drives the stem to open or close the valve. This allows for accurate control of fluid flow. The manual version is operated by a handle, providing a reliable option for situations where automation is not required.
3. **Key Technical Features:**
- New-style sanitary stop/switch valves offer enhanced safety, clearance, and durability.
- A separate design between the actuator and valve body allows for easy inspection of the shaft seal.
- Supports both "NC" (Normally Closed) and "NO" (Normally Open) functions for quick switching.
- Spherical valve body ensures smooth fluid flow and minimal resistance.
- Improved material handling with better performance and longevity.
- Standardized valve body design provides flexible connection options.
- Metal stop mechanism ensures long-lasting sealing performance.
- Easy assembly and maintenance for efficient service.
4. **Material Options:**
- Contact parts: Stainless Steel 304 or 316L
- Seal options:
- Soft seals: EPDM (standard), Silicone, FDM, HNBR (optional)
- Metal seals available upon request
5. **Advantages:**
- Excellent resistance to acids, alkalis, and high temperatures.
- Minimal permanent compression deformation.
- Investment forging plug offers superior pressure resistance (<1.2MPa).
- Modern and aesthetically appealing design that aligns with international trends.
- Cost-effective solution with reliable performance.
6. **Connection Types:**
