Balancing valve - 5/4"; Kv 15,83 IVAR.CIM 747

Product detailed description

This balancing valve is commonly used in residential and commercial heating and cooling systems to ensure even distribution of flow. Installers and service technicians use it to regulate differential pressure and flow rates in hydronic systems. The valve is suitable for applications where precise flow control is required, such as in underfloor heating, radiators, and fan coil units. It is typically installed in closed-loop systems where balancing is necessary to maintain system efficiency and prevent overloading of components.

The valve is constructed from CC752S brass, a material known for its durability and resistance to corrosion. It is designed to operate within a wide temperature range, from -10°C to +120°C, making it suitable for both heating and cooling applications. The PN 25 pressure rating ensures compatibility with systems operating under moderate pressure conditions. The Kv value of 15.83 is a key factor in determining the flow capacity and is essential for accurate system sizing and balancing calculations.

The operating temperature range from -10°C to +120°C allows the valve to be used in both heating and cooling systems. The PN 25 pressure rating indicates the valve is suitable for systems with moderate pressure levels. The Kv value of 15.83 is used to calculate the flow rate and is essential for determining the correct valve size for a given application. These parameters are critical for ensuring the valve is correctly selected and sized for the intended system.

Installation and connection

The valve is installed using a 5/4 inch connection, typically threaded. Before installation, it is important to verify the system pressure and temperature conditions to ensure compatibility with the valve's specifications. The valve should be installed in a straight section of pipe to avoid flow disturbances. Common installation mistakes include incorrect orientation, failure to check for debris in the pipeline, and not securing the valve properly. It is also important to ensure that the system is depressurised before beginning installation to prevent injury or damage.

Compatibility and accessories

The valve is compatible with standard heating and cooling systems that operate within the specified pressure and temperature ranges. It can be used with various types of flow meters and control systems. When installing, it is important to ensure that the system piping is compatible with the 5/4 inch connection. No additional accessories are required for basic operation, but in some cases, flow measuring devices may be added for more precise control.

Technical background for designers

The valve operates by adjusting the flow rate through the system, allowing for precise balancing of the hydraulic circuit. The CC752S brass construction provides good resistance to corrosion and wear, ensuring long-term reliability. The fixed end fittings allow for measurement without the need to drain the system, which is beneficial for maintenance and monitoring. The valve's performance is influenced by the system's pressure, temperature, and flow conditions. Proper sizing and installation are essential to ensure optimal performance and longevity.

Service and operation

The valve requires minimal maintenance due to its robust construction and simple design. It is important to periodically check for signs of wear or leakage, especially at the connection points. The valve should be inspected after any major system changes or if there are signs of reduced performance. No specific service intervals are provided, but regular visual inspections are recommended to ensure continued reliable operation.
