Dynamic balancing valve - without control insert - 1/2 "Fx1/2 "F IVAR.PICV 00

Product detailed description

Dynamic balancing valves are essential components in hydronic systems where consistent flow distribution is required. This IVAR model is commonly used in residential and commercial buildings for heating and cooling applications. Installers and system designers use it to ensure that each branch of the system receives the correct flow rate, regardless of pressure fluctuations. The valve is installed in individual circuits to maintain balance without manual adjustment after initial setup.

Proper installation and sizing are critical to achieving system efficiency. The valve must be placed in a location that allows for easy access for maintenance and inspection. It is typically installed in straight runs of pipe, away from turbulence-inducing components such as elbows or tees. The internal FF cap ensures a secure and leak-free connection within the system.

Technical parameters

Material	Brass CW617N
Operating temperature	-20 °C
Nominal pressure	PN 25
Code	590065
Brand	IVAR

The valve is rated for a maximum working pressure of PN 25, making it suitable for systems with moderate to high pressure requirements. The operating temperature range extends from -20°C to +120°C, allowing use in both heating and cooling systems. The material, brass CW617N, is selected for its durability and resistance to corrosion in water-based systems. These parameters are essential for correct sizing and selection to ensure compatibility with the system's design conditions.Installation and connection The valve is connected using 1/2 inch female threaded (F) connections on both ends. Installers should ensure that the pipe threads are clean and free of debris before tightening the connections. A wrench or pipe spanner should be used to secure the valve without over-tightening, which can damage the threads or seating surfaces. It is important to verify that the valve is installed in the correct orientation, with the flow direction matching the system design. Common installation mistakes include incorrect orientation, which can lead to improper balancing and reduced system performance.Compatibility and accessories This valve is designed for use with heating and cooling systems that require dynamic flow balancing. It is compatible with standard copper or steel piping systems with 1/2 inch internal female threaded fittings. For complete system functionality, the control insert must be ordered separately and installed within the valve body. The preparation for connection of measuring elements allows for integration with flow meters or other monitoring devices, which are not included with the valve.Technical background for designers The operating principle of this dynamic balancing valve is based on maintaining a constant flow rate regardless of pressure changes in the system. The valve body contains a mechanism that adjusts the internal orifice in response to flow variations, ensuring that the set flow rate is maintained. The brass CW617N material provides good mechanical strength and corrosion resistance, making it suitable for long-term use in water-based systems. The valve integrates into the system by being installed in individual circuits, where it acts as a self-regulating component. The efficiency and service life of the valve depend on the quality of the installation, the cleanliness of the system, and the absence of particulate matter in the fluid.Service and operation Routine maintenance is not required for this valve under normal operating conditions. However, periodic inspection is recommended to ensure that the internal components remain free of debris and that the connections remain secure. If the system experiences a drop in performance or unusual noise, the valve should be checked for blockages or wear. No specific service intervals are provided in the technical documentation, but it is advisable to follow the manufacturer's guidelines for any system-specific requirements.Frequently asked questions

Can this valve be used in a closed-loop cooling system?
Yes, the valve is suitable for use in closed-loop cooling systems as it is rated for temperatures up to +120°C and is compatible with water-based media.

Is the control insert included with the valve?
No, the control insert is not included and must be ordered separately for the valve to function as a complete dynamic balancing unit.

Can the valve be installed in a vertical position?
Yes, the valve can be installed in a vertical position as long as the flow direction is maintained and the internal components are not obstructed.

What is the maximum allowable pressure for this valve?
The valve is rated for a maximum working pressure of PN 25, making it suitable for systems with moderate to high pressure requirements.
