Balancing valve - 1/2"; Kv 1,75 IVAR.CIM 747

Product detailed description

This balancing valve is commonly used in residential and commercial buildings for the precise regulation of flow in heating and cooling systems. It is installed by HVAC technicians and plumbers to ensure even distribution of thermal energy across the system. The valve allows for the adjustment of differential pressure and flow rates, ensuring optimal system performance. It is particularly useful in systems where flow balancing is critical for efficiency and comfort.

Designed for integration into closed-loop systems, this valve is suitable for applications where accurate flow control is required. The installation typically involves connecting the valve into a pipe run and adjusting the flow to match design specifications. It is important to ensure that the system is depressurised and drained before installation to avoid damage or injury.

Technical parameters

The operating temperature range of -10°C to +120°C allows the valve to function in both heating and cooling applications. The PN 25 pressure rating indicates that it is suitable for systems with a maximum allowable working pressure of 25 bar. The CC752S brass material provides good corrosion resistance and mechanical strength, making it suitable for long-term use in a variety of environments.

Installation and connection

Installation should be carried out by a qualified technician. The valve is connected using a 1/2 inch thread, and it is essential to verify that the thread type matches the system piping. A common mistake is incorrect orientation of the valve, which can affect flow control and lead to system inefficiencies. Before tightening the connections, ensure that the sealing material is compatible with the system media and that the valve is fully open to avoid damaging the internal components during installation.

Compatibility and accessories

This valve is compatible with standard heating and cooling systems that use threaded connections. It is typically used in conjunction with differential pressure controllers and flow meters to achieve accurate system balancing. No additional accessories are required for basic operation, but system-specific components may be needed depending on the design requirements.

Technical background for designers

The valve operates by adjusting the flow resistance within the system, allowing for precise control of the flow rate. The CC752S brass material offers good thermal conductivity and resistance to mechanical stress, ensuring stable performance over time. The valve is designed to integrate seamlessly with other system components, and its performance is influenced by factors such as system pressure, temperature fluctuations and the presence of particulate matter in the fluid. Regular monitoring of the system can help identify potential issues before they impact efficiency.

Service and operation

While no specific service intervals are provided, routine checks for leaks and proper flow settings are recommended. The valve should be inspected for signs of wear or corrosion, particularly in systems with aggressive media. If the valve is not functioning as expected, it should be isolated and tested to determine the cause. In some cases, re-calibration may be necessary to restore accurate flow control.

Frequently asked questions

Can this valve be used in a closed-loop heating system?
Yes, the valve is suitable for use in closed-loop heating systems where flow balancing is required. It is designed to handle the typical operating conditions found in such systems.

What is the maximum operating temperature for this valve?
The valve can operate at temperatures up to +120°C, making it suitable for both heating and cooling applications.

Is this valve compatible with copper piping?
Yes, the valve can be connected to copper piping using a 1/2 inch thread. It is important to ensure that the thread type and sealing material are compatible with the piping material.

Can the valve be used in a system with a pressure higher than PN 25?
No, the valve is rated for a maximum allowable working pressure of PN 25. Using it in a system with higher pressure could result in failure or damage.
