Replaceable control insert - externally adjustable - 35-400 kPa; 238-896l/h; green IVAR.PICC 02

Product detailed description

Replaceable control inserts are essential components in heating and plumbing systems where precise flow control is required. These inserts are commonly used in commercial and industrial buildings, particularly in systems that require dynamic balancing. Installers and technicians working on HVAC systems will find these inserts useful for maintaining consistent flow rates across different zones. The inserts are typically installed in conjunction with balancing valves to ensure that each circuit receives the correct amount of flow, regardless of system pressure variations.

These inserts are used in systems where temperature fluctuations are common, such as in underfloor heating, radiant panels, or in systems with variable load conditions. The ability to adjust the flow externally allows for fine-tuning without the need to disassemble the entire valve. This makes maintenance and commissioning more efficient, especially in large-scale installations where multiple circuits need to be balanced.

Technical parameters

Material	Brass CW602N
Operating temperature	-20 °C
Nominal pressure	PN 25
Code	590121
Brand	IVAR

The operating temperature range of -20°C to +120°C makes this insert suitable for both cold and hot water applications. The nominal pressure rating of PN 25 indicates that it can handle systems with moderate pressure levels. The material, brass CW602N, is selected for its corrosion resistance and mechanical strength, ensuring long-term reliability in a range of environments. These parameters are critical for selecting the correct insert for a given system, particularly when considering thermal expansion and pressure fluctuations.

Installation and connection

Installation of the replaceable control insert requires the use of compatible dynamic balancing valves, such as the IVAR.PICV 00, 05, 100, 105, 200, or 205 models. The insert is inserted into the valve body and secured in place. It is important to ensure that the valve is fully closed before inserting the component to prevent damage. The external adjustment feature allows for flow rate adjustments without removing the insert. Common installation mistakes include incorrect insertion depth, which can affect flow characteristics, and failure to close the valve before installation, which can lead to media leakage or damage to the insert.

Compatibility and accessories

This control insert is specifically designed for use with the IVAR.PICV series of dynamic balancing valves. When ordering, ensure that the correct valve model is selected to match the insert. No additional accessories are required for standard installation. The insert is not interchangeable with other valve types or models outside the specified series. Installers should verify the valve model before fitting the insert to avoid compatibility issues.

Technical background for designers

The operating principle of this control insert is based on a fixed orifice design, where the flow rate is adjusted by changing the effective cross-sectional area of the insert. The brass CW602N material provides good thermal conductivity and resistance to corrosion, making it suitable for use in both hot and cold water systems. The insert is integrated into the valve body and works in conjunction with the valve's internal mechanism to regulate flow. The service life and efficiency of the insert depend on the quality of the installation, the operating conditions, and the frequency of adjustments. Regular inspection for wear or damage is recommended to maintain system performance.

Service and operation

While no specific service intervals are provided, it is advisable to inspect the insert periodically for signs of wear or blockage. The external adjustment feature allows for easy flow rate adjustments without the need to remove the insert. During maintenance, ensure that the system is depressurised and the valve is closed before making any adjustments. If the insert shows signs of corrosion or deformation, it should be replaced to maintain accurate flow control. No special tools are required for adjustment or inspection.

Frequently asked questions

Can this insert be used with any dynamic balancing valve?
No, it is only compatible with the IVAR.PICV 00, 05, 100, 105, 200, and 205 models. Using it with other valve types may result in improper operation or damage.

Is it possible to adjust the flow rate without removing the insert?
Yes, the external adjustment feature allows for flow rate changes without disassembling the valve or removing the insert.

What is the maximum operating temperature for this insert?
The insert is rated for operation up to +120°C, making it suitable for hot water and heating applications.

Can the insert be replaced without replacing the entire valve?
Yes, the insert is designed to be replaced independently of the valve body, which helps reduce maintenance costs and downtime.
