5. Operation Instructions for Sanitary Square Three-Way Ball Valve

To ensure optimal performance, it is essential to follow the proper operating procedures for the Sanitary Square Three-Way Ball Valve.

Step 1: Valve Orientation:

Before installation, ensure that the valve’s flow direction is aligned with your system’s flow requirements. The valve should be installed such that the flow markings match the desired flow path (straight-through, diversion, or mixing).

Step 2: System Preparation:

• Ensure the system is depressurized before installation to prevent leakage and ensure safety.

• Confirm that the correct valve size and type are selected for your system.

Step 3: Installation:

• Flanged Connections: Attach the valve to the system using flanged connections. Tighten the bolts in a cross-pattern to ensure even pressure distribution and prevent leakage.

• Tri-Clamp Connections: For hygienic applications, use Tri-Clamp connections for easy disassembly and cleaning.

• Threaded Connections: Ensure the threads are properly sealed to avoid leakage.

Step 4: Valve Operation:

• The valve can be operated manually or pneumatically, depending on the handle type.

• Manual Operation: Turn the valve handle to adjust the flow. The valve’s ball mechanism will either divert or mix the flow, depending on the configuration.

• Pneumatic Operation: For automated systems, use a pneumatic actuator to control the valve remotely.

6. Testing and Quality Assurance

To ensure the Sanitary Square Three-Way Ball Valve performs to its full potential, it undergoes several testing procedures before delivery. These include:

1. Pressure and Leakage Testing:

• The valve is subjected to hydrostatic testing to ensure it can withstand the rated pressure without any leakage.

• Leakage testing is performed under standard conditions to check for any leakage around the seals or connections.

2. Functional Testing:

• The valve is tested to ensure smooth and efficient operation of the ball mechanism and handle.

• All flow paths (diverting, mixing, and straight-through) are tested to ensure they function as intended.

3. Surface and Finish Quality Inspection:

• The valve’s internal and external surfaces are inspected to ensure that they meet the required sanitary standards for cleanliness and smoothness.

• Any imperfections that could harbor bacteria or cause contamination are corrected before the valve is shipped.

7. Maintenance Recommendations

Proper maintenance ensures the longevity and optimal performance of the Sanitary Square Three-Way Ball Valve. Below are the recommended maintenance steps:

1. Cleaning:

• Clean the valve using a CIP (Clean-In-Place) system for continuous sanitary processes.

• If manual cleaning is needed, use non-abrasive cleaners and food-grade disinfectants.

2. Seal Inspection and Replacement:

• Inspect the seals regularly for signs of wear, cracking, or degradation. Replace seals if they are damaged to prevent leakage.

3. Lubrication:

• If the valve is manual, lubricate the handle mechanism regularly to ensure smooth operation.

4. Inspection:

• Daily or Weekly: Inspect the valve for any visible leaks, wear, or damage.

• Annual Maintenance: Disassemble the valve for a complete inspection, and replace any worn-out components.
