Balancing valve - 3/4"; Kv 2,87 IVAR.CIM 787

Product detailed description

Installers working on residential and commercial heating and cooling systems often require precise flow control to ensure even distribution of thermal energy. This balancing valve is suitable for use in underfloor heating, radiators, and fan coil units. It allows for the adjustment of differential pressure and flow rate, ensuring optimal system performance. The valve includes fixed end fittings for measurement without the need for draining the system, making it ideal for installations where access is limited or system downtime must be minimized.

The valve is commonly used in systems where accurate balancing is essential for energy efficiency and occupant comfort. It is particularly useful in multi-zone systems where individual circuits need to be adjusted independently. The brass construction ensures durability in both hot and cold water applications, and the PN 25 pressure rating makes it suitable for high-pressure environments.

The PN 25 rating indicates that the valve is suitable for systems with a maximum allowable working pressure of 25 bar at standard operating temperatures. The CW602N-M brass material is resistant to corrosion and suitable for use with potable and non-potable water. The flow coefficient (Kv) of 2.87 is essential for calculating the required valve size and ensuring that the system achieves the desired flow rate and pressure drop.Installation and connection The valve is installed in a straight section of pipe to ensure accurate flow measurement and control. The 3/4 inch connection requires a compatible pipe size and fitting. Before installation, verify that the system is depressurized and that the valve is oriented correctly according to the flow direction. Common installation errors include incorrect orientation, which can lead to inaccurate balancing and increased pressure drop. Ensure that the valve is fully open during installation and that the system is flushed to remove debris before commissioning.Compatibility and accessories This valve is compatible with standard heating and cooling system components, including radiators, heat emitters, and fan coil units. For complete system integration, it is recommended to use compatible pipe fittings and insulation materials. No additional accessories are required for basic operation, but pressure and flow measuring devices may be needed for system commissioning and maintenance.Technical background for designers The valve operates by adjusting the cross-sectional area of the flow path to control the volume of fluid passing through. The CW602N-M brass material offers good mechanical strength and resistance to thermal expansion, making it suitable for long-term use in fluctuating temperature conditions. The PN 25 rating ensures that the valve can withstand high-pressure environments without deformation or leakage. The fixed end fittings allow for direct connection to measurement instruments, eliminating the need for additional adapters or fittings. The valve's performance is influenced by the system's overall hydraulic design, including pipe diameter, pump capacity, and the presence of other balancing components.Service and operation Regular inspection of the valve is recommended to ensure that it remains free from debris and that the adjustment mechanism operates smoothly. No scheduled service intervals are specified, but the valve should be checked during routine system maintenance. If the valve is suspected of being faulty, it should be isolated and tested using standard diagnostic procedures. The CW602N-M brass construction ensures long-term durability, but it is important to avoid exposure to aggressive chemicals or extreme temperatures outside the specified range.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. The PN 25 pressure rating ensures compatibility with typical system pressures.

Is it possible to integrate this valve with a remote control system?
While the valve itself does not have remote control capabilities, it can be used in conjunction with external sensors and actuators for automated balancing in advanced systems.

Can the valve be used with glycol-based fluids?
Yes, the CW602N-M brass material is compatible with glycol-based fluids commonly used in heating and cooling applications. No special precautions are required for this use.

What is the maximum allowable temperature for this valve?
The valve is rated for operation up to +120 °C, making it suitable for both hot and cold water applications in heating and cooling systems.
