• Do not exceed the maximum operational pressure of 10 bar or the specified temperature range of -10 °C to 110 °C.
• The maximum glycol percentage in the system fluid should not exceed 50%.
• Wear appropriate personal protective equipment (PPE) during installation and maintenance.

Product Overview and Components

The CALEFFI 132902 is a robust flow balancing valve featuring an integrated direct-reading flow meter for accurate system control.

Image Description: This image displays the CALEFFI 132902 Flow Balancing Valve. It is constructed with a brass body and includes a black flow meter unit with a visible red indicator for flow rate. A control knob is located on the side for flow adjustment, and the valve is equipped with threaded connections for system integration.

Key Components:

• Valve Body: Constructed from durable brass, ensuring longevity and resistance to corrosion.
• Flow Meter: Provides direct and accurate reading of the fluid flow rate. Features a clear scale and a magnetic movement indicator for easy monitoring.
• Ball Valve: Integrated for precise flow regulation and control within the system.
• Insulation: Included to help maintain system temperature and prevent unwanted heat loss or gain.

Setup and Installation

The CALEFFI 132902 valve is designed for integration into hydronic systems. Proper installation is crucial for optimal performance.

• System Preparation: Ensure the system is clean and free of debris before installation to prevent damage or blockages.
• Mounting: Install the valve in the correct flow direction as indicated on the device. Use appropriate sealing materials for threaded connections to ensure a leak-free seal.
• Connection: Connect the valve securely to the piping system, ensuring all joints are tight and properly sealed.
• Pressure Test: After installation, perform a system pressure test to verify integrity and check for any leaks before commissioning.

Operating Instructions

Flow Rate Reading:

The integrated flow meter allows for direct reading of the current fluid flow rate. Observe the red indicator against the graduated scale on the flow meter to determine the flow in liters per minute (L/min).

Flow Regulation:

To adjust the flow rate, use the ball valve control knob. Rotate the knob to either increase or decrease the flow as required by the system design specifications. Make adjustments slowly and observe the flow meter for real-time feedback on the flow rate.

Maintenance

Regular maintenance ensures optimal performance and extends the operational life of your CALEFFI 132902 valve.

• Periodic Inspection: Periodically inspect the valve for any signs of leaks, corrosion, or physical damage. Address any issues promptly.
• Cleaning: Ensure the flow meter's viewing window remains clear for accurate readings. Clean gently with a soft cloth if necessary.
• System Flushing: If the system fluid becomes contaminated, flush the system according to manufacturer guidelines to prevent blockages in the valve or flow meter.

Troubleshooting

Refer to the following common issues and solutions. For complex problems, consult a qualified professional.

• No Flow Reading: Check for blockages in the system or within the flow meter. Ensure the system pump is operating correctly and there is adequate fluid circulation.
• Incorrect Flow Reading: Verify that the valve is installed in the correct flow direction. Ensure the system is free of air pockets, which can affect readings.
• Leaks: If minor leaks are observed at connections, gently tighten them. If leaks persist or are significant, professional inspection and repair may be required.
• For any issues not covered here or if problems persist, consult a qualified HVAC professional.
