Replaceable control insert - without external adjustment - 40-400kPa; 493-1470l/h; green IVAR.PICC 01

Product detailed description

Replaceable control inserts are essential components in dynamic balancing systems for heating and plumbing installations. These inserts allow precise flow regulation in variable load conditions, ensuring stable performance in residential, commercial and industrial buildings. Installers working on central heating systems, underfloor heating circuits or domestic hot water loops frequently use these inserts to maintain system balance without manual readjustment. The modular design allows quick replacement during maintenance without removing the entire valve body.

In multi-zone heating systems, these inserts help maintain consistent flow rates across different branches. They are commonly found in systems with circulating pumps and thermostatic controls, where flow stability is critical. The insert's fixed flow settings simplify commissioning and reduce the need for frequent adjustments, making it suitable for both new installations and retrofit projects.

Technical parameters

Material	Brass CW602N
Operating temperature	-20 °C
Nominal pressure	PN 25
Code	590109
Brand	IVAR

The PN 25 rating indicates the insert is suitable for systems operating at nominal pressures up to 25 bar. The operating temperature range from -20°C to +120°C makes it compatible with both chilled and heated water applications. These parameters are essential for determining correct sizing and ensuring long-term reliability in the intended system environment.

Installation and connection

Before installation, verify that the insert matches the designated valve model and flow setting requirements. The insert is inserted into the valve body using a push-fit mechanism and secured through mechanical alignment. Ensure the sealing surfaces are clean and free of debris before fitting. Common installation errors include incorrect orientation and failure to align internal flow passages. Always cross-check the flow setting code with the system design specifications before final installation.

Compatibility and accessories

This insert is specifically designed for use with IVAR.PICV 00 and 05 series dynamic balancing valves. For larger systems requiring higher flow capacities, ensure the corresponding valve model is selected based on hydraulic calculations. Additional components such as isolation valves and pressure gauges may be required for system commissioning and monitoring.

Technical background for designers

The insert operates by restricting flow through a fixed orifice, maintaining consistent flow rates despite pressure variations. The brass CW602N construction provides high corrosion resistance and mechanical strength, while the plastic components reduce weight and improve durability in fluctuating temperatures. Integration into the system requires consideration of upstream and downstream pressure differentials to avoid cavitation or flow instability. System efficiency depends on accurate matching of the insert's flow characteristics with the overall circuit demand.

Service and operation

Routine inspections should focus on checking for signs of wear or blockage in the flow passages. If flow irregularities occur, disassemble the valve and inspect the insert for debris accumulation. No scheduled service intervals are specified; however, replacement should be performed if flow deviation exceeds acceptable limits or if physical damage is detected.

Frequently asked questions

Can this insert be used with any dynamic balancing valve?
It is specifically designed for use with IVAR.PICV 00 and 05 series valves. Using it with other models may result in improper fit or flow performance.

How does the operating temperature affect performance?
The insert functions reliably between -20°C and +120°C. Extreme temperatures outside this range may affect material integrity and flow stability.

What is the significance of the PN 25 rating?
The PN 25 indicates the insert is suitable for systems with nominal pressures up to 25 bar. This rating ensures compatibility with standard heating and plumbing system pressures.

Are there any limitations on the number of flow settings?
This model offers eight preset flow settings. Each corresponds to specific flow rates and is selected based on the system design requirements.
