Replaceable control insert - without external adjustment - 22-300kPa; 828-3020l/h; white IVAR.PICC 11

Product detailed description

Replaceable control inserts are essential components in dynamic balancing systems, ensuring consistent flow rates in heating and plumbing installations. This insert is commonly used in residential and commercial buildings where precise flow control is required. It is typically installed in systems where external adjustment is not necessary, allowing for pre-set flow values to be maintained across varying system conditions. Installers working on central heating systems, underfloor heating, or domestic hot water circuits will find this insert suitable for applications where flow stability is critical.

When integrating this control insert into a system, the installer must ensure compatibility with the selected dynamic balancing valve. The insert is designed to fit within the valve body and provides a fixed flow characteristic without the need for manual adjustment. This makes it ideal for applications where flow rates are pre-determined and must remain constant, such as in pre-balanced systems or where zoning is managed by other means. The insert is typically installed during the initial setup of the system and requires no further adjustment once in place.

Technical parameters

Material	Brass CW602N
Operating temperature	-20 °C
Nominal pressure	PN 25
Code	590112
Brand	IVAR

The operating temperature range of -20°C to +120°C allows for use in a wide range of environments, including systems with glycol mixtures or in cold climates. The PN25 rating indicates the maximum allowable pressure for the insert, ensuring it is suitable for systems with moderate to high pressure conditions. The brass CW602N material provides good corrosion resistance and mechanical strength, making it suitable for long-term use in water-based systems. These parameters are essential for correct sizing and selection, particularly when matching the insert to the system's hydraulic requirements.

Installation and connection

The insert is installed within the body of a compatible dynamic balancing valve, such as the IVAR.PICV 100 or 105 models. It is secured in place using the valve's internal mechanism and does not require external adjustment. During installation, the technician should verify that the insert is seated correctly and that there is no misalignment that could affect flow performance. Common installation mistakes include using the wrong insert for the valve model or failing to ensure a secure fit, which can lead to leakage or inconsistent flow rates. The connection sizes and thread types are determined by the valve body, so no additional fittings are required for the insert itself.

Compatibility and accessories

This insert is specifically designed for use with the IVAR.PICV 100 and 105 dynamic balancing valves. It is not compatible with other valve models or with valves that require external adjustment. When ordering, the technician should ensure that the correct valve body is also available. No additional accessories are required for installation, as the insert is a self-contained component. However, it is important to confirm that the valve body is compatible with the system's pressure and temperature conditions before installation.

Technical background for designers

The operating principle of this control insert is based on a fixed orifice design, which restricts flow to a pre-determined value. The brass CW602N material is chosen for its durability and resistance to corrosion, ensuring long-term performance in water-based systems. The insert is integrated into the valve body and works in conjunction with the valve's internal mechanism to maintain a constant flow rate regardless of pressure fluctuations. The service life and efficiency of the insert are influenced by the quality of the installation, the cleanliness of the system, and the absence of particulate matter that could clog the orifice. Proper system design and filtration are essential to prevent premature wear or blockage.

Service and operation

This insert does not require regular maintenance or service intervals, as it is a fixed component with no moving parts. However, it should be inspected periodically for signs of wear, corrosion, or blockage. If the system experiences a drop in performance or inconsistent flow rates, the insert should be removed and checked for debris or damage. In such cases, it may be necessary to replace the insert with a new one. No specific service procedures are required beyond visual inspection and cleaning if necessary.

Frequently asked questions

Can this insert be used with valves other than IVAR.PICV 100 or 105?
No, it is specifically designed for use with these valve models and is not compatible with other types of dynamic balancing valves.

Is it possible to adjust the flow rate after installation?
No, the insert provides fixed flow settings and cannot be adjusted externally once installed.

Can this insert be used in systems with glycol mixtures?
Yes, the operating temperature range includes -20°C, making it suitable for systems using glycol-based fluids.

What is the maximum operating pressure for this insert?
The insert is rated for PN25, which means it can handle a maximum pressure of 25 bar at standard operating temperatures.
