2. Key Functions of the Sanitary Threaded Forged Three-Way Ball Valve

The Sanitary Threaded Forged Three-Way Ball Valve offers a range of functionalities that are vital in industries requiring precise fluid control.

1. Flow Diversion:

The valve can divert flow from one inlet to two outlets or vice versa, allowing for flexibility in directing fluid or gas through different channels. This function is ideal for systems where fluid needs to be rerouted depending on operational requirements.

• Application Example: In food processing, this valve can divert ingredients from a central supply to different stages of production without contamination.

2. Flow Mixing:

This valve can combine two flow sources into one, providing a controlled mixing of fluids. It’s commonly used in chemical, pharmaceutical, and beverage production where different fluids or chemicals need to be blended before proceeding to the next stage.

• Application Example: In the pharmaceutical industry, the valve can mix two different active ingredients before they are processed further.

3. On/Off Flow Control:

The valve can also function as an on/off valve, used in applications where precise shut-off control is necessary. When fully closed, the valve completely blocks fluid flow, ensuring no leakage or cross-contamination.

• Application Example: Used in biotech applications to isolate sections of a pipeline during maintenance or cleaning.

4. Sanitary Flow Regulation:

Due to its design, this valve ensures smooth fluid flow with minimal turbulence, making it ideal for sanitary applications that require strict control over fluid dynamics.

3. Operation Instructions for the Sanitary Threaded Forged Three-Way Ball Valve

To ensure the Sanitary Threaded Forged Three-Way Ball Valve operates at optimal performance, it is essential to follow correct installation and operation procedures.

Step 1: Pre-Installation Checks

Before installation, ensure the valve is the correct size and type for your system. Check the valve for any visible damage and verify that the threaded connections match your piping system's specifications (BSPT or NPT). Always ensure the system is depressurized before handling the valve.

Step 2: Installing the Valve

• Threaded Connections: Screw the valve into the threaded piping system. Apply thread sealant to the threads to prevent leakage and ensure a secure seal.

• Torque Specification: Tighten the valve carefully using the appropriate tools, ensuring it is secure but not over-tightened. Follow the manufacturer’s torque specifications to avoid damage to the valve or threads.

Step 3: Operating the Valve

• Manual Operation: Turn the handle or actuator to adjust the flow. Depending on the valve design (L-port or T-port), the valve will either divert or mix the fluid flow.

• Pneumatic Operation: For automatic systems, connect the valve to a pneumatic actuator for remote operation. Ensure the actuator is properly calibrated to control the valve’s position accurately.

Step 4: Testing the Valve

After installation, slowly pressurize the system and check for leaks. Test the valve by operating it through its full range (on/off, diverting, or mixing), ensuring smooth and responsive movement without resistance or leaks.

4. Environmental and Safety Standards Compliance

The Sanitary Threaded Forged Three-Way Ball Valve complies with various sanitary, safety, and environmental regulations, ensuring that it meets the stringent demands of industries like food and beverage, pharmaceuticals, and biotechnology.

Environmental Standards:

• FDA: The valve complies with the FDA standards for materials used in food contact applications, ensuring safety and hygiene.

• 3A Sanitary Standards: Meets the 3A standards for hygienic equipment used in the dairy and food processing industries.

• EHEDG: The valve is designed in accordance with EHEDG (European Hygienic Engineering & Design Group) guidelines, which ensures it meets the strict hygiene requirements for processing and packaging of food products.

• CE Marking: This certification indicates that the valve complies with the relevant EU legislation concerning safety and environmental protection.

Operational Safety:

• The valve is designed with smooth internal surfaces that reduce the risk of bacterial buildup, ensuring the system remains safe and hygienic.

• Pressure and Temperature Limits: The valve is engineered to handle a wide range of pressures (up to 10 bar) and temperatures (up to 150°C), ensuring it operates safely in diverse environments.

5. Common Issues and Troubleshooting

While the Sanitary Threaded Forged Three-Way Ball Valve is a reliable and durable product, it may experience some common issues over time. Below are some troubleshooting steps for frequently encountered problems:

1. Leaks at the Threaded Connections:

• Cause: Loose or damaged threaded connections.

• Solution: Tighten the valve using a wrench, ensuring it is not over-tightened. If the problem persists, check the thread sealant for degradation and replace if necessary.

2. Valve Sticking or Difficult to Operate:

• Cause: Lack of lubrication or debris in the valve mechanism.

• Solution: Clean the valve thoroughly and lubricate the handle or actuator with a food-grade lubricant. Regularly maintain the valve to prevent dirt buildup.

3. Inconsistent Flow or Blockage:

• Cause: Debris or foreign particles blocking the flow path inside the valve.

• Solution: Disassemble the valve and clean the internal components using a sanitary-grade cleaner. Inspect for wear and replace damaged parts as necessary.

4. Poor Performance in Diverting or Mixing:

• Cause: Incorrect installation or valve misalignment.

• Solution: Double-check the valve’s orientation before installation to ensure it matches the desired flow path (L-port or T-port). Reinstall if necessary.

6. Maintenance and Care Tips

To ensure the longevity and optimal performance of the Sanitary Threaded Forged Three-Way Ball Valve, follow these maintenance guidelines:

1. Regular Cleaning:

• CIP (Clean-In-Place) systems are the preferred method for cleaning the valve in continuous production environments. If manual cleaning is required, disassemble the valve and clean it using non-abrasive cleaners and food-grade disinfectants.

2. Seal and Component Inspection:

• Regularly inspect the valve seals, ball mechanism, and other components for wear or damage. Replace seals as necessary to prevent leakage and maintain proper function.

3. Lubrication:

• Ensure the valve handle or actuator is properly lubricated with a food-safe lubricant. This will help prevent rust and ensure smooth operation.

4. Periodic Testing:

• Test the valve periodically to ensure proper flow control, pressure resistance, and leak-tight operation. This will help identify potential issues before they become major problems.
