Balancing valve - 5/4"; Kv 6,71 IVAR.CIM 787

Product detailed description

This balancing valve is commonly used in residential and commercial buildings for hydronic heating and cooling systems. Installers and service technicians use it to ensure balanced flow distribution and maintain stable differential pressure. The valve integrates into systems requiring accurate hydraulic control and includes fixed measuring components for monitoring without draining the system. Proper installation ensures efficient system performance and long-term reliability.

Correct sizing and selection are critical for system compatibility. The valve is suited for applications where flow regulation and pressure stability are required. It is typically installed in closed-loop systems, such as underfloor heating, fan coil units, and radiators. The design supports integration with control systems and allows for manual or automatic adjustments depending on the system configuration.

The operating temperature range from -10°C to +120°C makes it suitable for both heating and cooling applications. The PN 25 rating indicates its ability to handle medium-pressure environments. The CW602N-M brass construction offers good corrosion resistance and mechanical strength, which is essential for long-term operation in water-based systems. These parameters help determine correct sizing and compatibility with existing piping and system requirements.

Installation and connection

Before installation, confirm that the valve matches the system’s pressure and temperature requirements. The valve connects using standard pipe threads and requires alignment with the flow direction as indicated on the body. Ensure that the surrounding piping is clean and free of debris to prevent internal damage. Secure the valve using appropriate fittings and tighten connections evenly to avoid stress on the body. A common mistake is incorrect orientation, which can lead to improper flow or damage to the measuring elements. Always verify that the system is depressurised before beginning installation.

Compatibility and accessories

This valve is compatible with standard copper and steel piping systems. For complete system functionality, it should be used alongside pressure gauges, flow meters, and control valves. Additional accessories may include mounting brackets or insulation materials depending on the application. Ensure that all components are rated for the same pressure and temperature conditions to maintain system integrity.

Technical background for designers

The valve operates by adjusting the flow cross-section to regulate the fluid rate and maintain a set differential pressure. The brass body provides good thermal conductivity and mechanical stability, while the CW602N-M alloy resists corrosion from water and antifreeze solutions. The fixed measuring elements allow for accurate readings without interrupting the system. System efficiency depends on proper sizing, correct installation, and regular monitoring to prevent blockages or wear.

Service and operation

Periodic inspection is recommended to ensure the valve remains free of debris and operates smoothly. Check the sealing surfaces and threaded connections for signs of leakage or wear. Clean the internal components if necessary, following the manufacturer’s guidelines. No specific service intervals are provided in the technical data, but visual and functional checks should be part of routine system maintenance.
