• Chemical Processing: Accurate powder handling in chemical production and packaging systems.

2. Structural Description

The Sanitary Handwheel Powder Discharge Butterfly Valve is designed with simplicity and efficiency in mind. Below is an in-depth look at its key structural components:

1. Valve Body:

• Material: The valve body is made from 304 or 316L stainless steel, offering superior resistance to corrosion and high durability.

• Shape: The valve features a butterfly design, where a disc is positioned in the center of the flow path. When the valve is opened, the disc rotates to allow material to flow, and when closed, the disc creates a seal to prevent leakage.

2. Handwheel:

• The handwheel is used for manually operating the valve. It connects directly to the valve stem, allowing for easy adjustment of the disc’s position.

• Ergonomically Designed: The handwheel is designed for easy grip and rotation, even in environments where gloves are worn.

• Material: Constructed from stainless steel for durability, it is resistant to wear and tear from constant use.

3. Seals and Gaskets:

• Material: The seals are typically made from EPDM, PTFE, or NBR, depending on the application requirements.

• These seals prevent leakage of powders, ensuring that no contamination occurs during operation.

4. Actuator (Optional):

• In addition to manual handwheel operation, the valve can be fitted with an electric or pneumatic actuator for automated control in larger systems.

• Materials: Actuators are typically made from aluminum or stainless steel, providing long service life in high-demand environments.

5. End Connections:

• The valve can be configured with flanged, tri-clamp, or threaded connections, allowing it to integrate seamlessly into existing systems.

6. Flow Direction:

• The valve is designed with an indicated flow direction, ensuring that the powder flows through the system in the correct direction for optimal operation.

3. Packaging Information

Proper packaging is essential to ensure the safe delivery and storage of the Sanitary Handwheel Powder Discharge Butterfly Valve. The valve is typically packaged as follows:

Packaging Materials:

• Individual Packaging: Each valve is carefully wrapped in bubble wrap or foam to protect it from damage during transportation.

• Outer Packaging: The valve is placed in a corrugated cardboard box or wooden crate, depending on size, to prevent external damage during shipping.

• Seals: Each valve is sealed to ensure cleanliness, preventing any contamination during transit.

Shipping Details:

• International Shipping: The valves can be shipped worldwide via sea freight, air freight, or courier services, depending on customer preferences and delivery timelines.

• Customs Compliance: Shipping documentation is provided to meet international customs requirements, including product specifications, materials, and certifications.

4. Storage Conditions

Proper storage of the Sanitary Handwheel Powder Discharge Butterfly Valve is vital to maintain its integrity and functionality. Here are the recommended storage conditions:

1. Temperature:

• Store the valve in a cool, dry place with a temperature range between -10°C and 40°C (14°F to 104°F) to avoid material degradation.

2. Humidity:

• Keep the valve in a low-humidity environment to prevent rust or corrosion. Excess moisture can also degrade the seals and other components over time.

3. Protection from Contaminants:

• Ensure the valve is sealed in its original packaging or covered with protective plastic to avoid exposure to dust, dirt, or other contaminants.

• Storage Orientation: Store the valve upright, avoiding heavy objects on top that may cause damage.

4. Avoid Direct Sunlight:

• Do not expose the valve to direct sunlight for extended periods, as UV exposure can degrade the material, especially rubber seals and gaskets.

5. Usage Recommendations

To ensure the Sanitary Handwheel Powder Discharge Butterfly Valve operates at its best, the following usage recommendations should be followed:

1. System Integration:

• Correct Sizing: Choose the appropriate valve size based on your system's pipeline diameter and expected flow rates. Using a valve that is too small or too large can cause inefficiencies or operational issues.

• End Connections: Make sure the valve's end connections (flanged, tri-clamp, or threaded) are compatible with your piping system. This ensures a secure and leak-proof installation.

2. Operating Pressure and Temperature:

• Ensure that the operating pressure and temperature conditions do not exceed the valve's maximum ratings, which are typically 10 bar (145 psi) and 150°C (302°F). Exceeding these limits can cause damage to the valve body, seals, and internal components.

3. Flow Control:

• The handwheel allows for precise flow control of powders. Always adjust the handwheel slowly and carefully to avoid over-tightening or damaging the internal components. Avoid sudden movements that may disrupt the flow or cause blockages.

4. Regular Cleaning:

• Clean-In-Place (CIP) systems are recommended for industries like food processing and pharmaceuticals. Regular cleaning is essential to remove any residual powders and prevent contamination.

• Use only food-safe or pharmaceutical-grade cleaning agents to avoid damaging the valve components or contaminating your product.

5. Maintenance:

• Inspect seals and gaskets regularly for wear and replace them as needed. Use only genuine replacement parts to maintain the valve's integrity.

• If the valve is part of a high-volume production system, schedule routine inspections to ensure the valve’s seals, handwheel, and disc are functioning correctly.
