Balancing valve - 1"; Kv 4,08 IVAR.CIM 787

Product detailed description

Thermal balancing valves are essential components in the design and maintenance of heating and cooling systems in residential, commercial and industrial buildings. Installers and service technicians regularly encounter the need to adjust and balance fluid flow in radiators, underfloor heating circuits, and air handling units. These valves ensure that each component in the system receives the correct flow rate, maintaining efficiency and comfort. In multi-zone systems, where different areas require varying levels of heating or cooling, balancing valves help achieve uniform performance across the entire installation.

Properly sized and installed balancing valves are critical for system efficiency. They allow for precise control of flow rates and pressure drops, preventing issues such as over- or under-supply in specific zones. This is particularly important in systems with variable flow rates or those that operate under fluctuating load conditions. The valve must be selected based on the system's hydraulic requirements, including the required flow coefficient (Kv), connection size, and operating temperature range.

Technical parameters

Operating temperature	-10 °C
Nominal pressure	PN 25
Weight	0.524 kg
Code	787100
Brand	IVAR

The valve is rated for a nominal pressure of PN 25, indicating its suitability for systems operating under moderate pressure conditions. The operating temperature range spans from -10 °C to +120 °C, making it appropriate for both heating and cooling applications. The CW602N-M brass construction provides good corrosion resistance and mechanical strength, ensuring durability in a variety of environments. These parameters are essential for determining compatibility with the system's hydraulic and thermal conditions.

Installation and connection

This valve is designed for 1 inch pipe connections, typically using threaded or flanged fittings depending on the system configuration. During installation, it is important to ensure that the valve is oriented correctly, with the flow direction indicated on the body. Installers should verify that the system pressure does not exceed the PN 25 rating and that the operating temperature remains within the specified range.

Compatibility and accessories

This balancing valve is compatible with standard heating and cooling systems that require flow regulation. It can be integrated with differential pressure controllers and flow meters to enhance system performance. For installations requiring remote monitoring or adjustment, additional accessories such as actuators may be necessary. While no specific related products are listed, installers should ensure that all components in the system are compatible with the valve's material and operating conditions.

Technical background for designers

The valve operates by adjusting the flow cross-section to control the volume of fluid passing through. The CW602N-M brass material offers good thermal conductivity and resistance to corrosion, making it suitable for both hot and cold water systems. The valve's design allows for precise flow setting and differential pressure control, which is essential for maintaining system balance. The PN 25 rating ensures that the valve can handle the typical pressures encountered in heating and cooling systems. Long-term performance depends on proper installation, regular maintenance, and adherence to the specified operating conditions.

Service and operation

Regular inspection of the valve is recommended to ensure that it continues to operate efficiently. Technicians should check for signs of wear, leakage, or blockage that could affect flow control. The valve should be cleaned if necessary, and any damaged components should be replaced. No specific service intervals are provided, but maintenance should be carried out in accordance with the manufacturer's technical data sheet. During operation, it is important to monitor the system's pressure and temperature to ensure that the valve remains within its specified limits.

Frequently asked questions

Can this valve be used in both heating and cooling systems?
