Replaceable control insert - without external adjustment-15-130kPa; 936-3060l/h; red IVAR.PICC 11

Product detailed description

Replaceable control inserts are used in dynamic balancing systems to regulate flow rates in heating and plumbing applications. These inserts are typically installed in valves that are part of larger systems such as underfloor heating, radiant panels, or district heating networks. Installers and service technicians use these inserts to ensure consistent flow distribution across multiple circuits. The absence of external adjustment means the flow setting is fixed at the time of installation, making it suitable for pre-set balancing scenarios.

These inserts are commonly found in commercial and industrial buildings where precise flow control is required. They are integrated into systems where thermal comfort and energy efficiency are prioritised. The insert is designed to be used in conjunction with specific valve bodies, ensuring compatibility and ease of installation. The fixed flow settings allow for accurate system balancing without the need for on-site adjustments.

Technical parameters

Material	Brass CW602N
Operating temperature	-20 °C
Nominal pressure	PN 25
Code	590111
Brand	IVAR

The operating temperature range of -20 °C to +120 °C allows the insert to be used in both cold and hot water systems. The nominal pressure rating of PN 25 indicates that the insert is suitable for medium-pressure applications. 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 essential for determining the suitability of the insert for a specific system and for ensuring correct sizing and selection.

Installation and connection

Installation of the insert requires the use of a compatible valve body, specifically the IVAR.PICV 100 or 105. The insert is inserted into the valve body and secured according to the manufacturer's instructions. The connection size is determined by the valve body and is typically sized to match the system piping. During installation, it is important to ensure that the insert is fully seated and that there is no misalignment, which could lead to leakage or improper flow control. A common mistake is attempting to adjust the insert after installation, which is not possible due to the absence of external adjustment features.

Compatibility and accessories

This insert is specifically designed for use with the IVAR.PICV 100 and 105 dynamic balancing valves. When ordering, it is important to ensure that the valve body is compatible with the insert. No additional accessories are required for installation, as the insert is a standalone component. It is recommended to order the insert in conjunction with the appropriate valve body to ensure system compatibility and correct operation.

Technical background for designers

The operating principle of the insert is based on a fixed orifice that restricts flow to a predetermined value. 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 plastic components are used for internal sealing and insulation, ensuring a tight fit and preventing leakage. The insert is integrated into the system as part of a pre-balanced valve, allowing for accurate flow distribution without the need for manual adjustment. The service life and efficiency of the insert are influenced by the quality of the installation, the operating conditions, and the compatibility with the valve body.

Service and operation

Due to the absence of external adjustment features, the insert does not require regular maintenance. However, it is important to inspect the valve body and surrounding components for signs of wear or damage. If the system is not operating as expected, the insert should be removed and inspected for blockages or deformation. There are no specified service intervals for this component, as it is designed for long-term use without adjustment. In the event of a failure, the insert can be replaced with a new unit of the same model.

Frequently asked questions

Can the insert be used in a system with variable flow conditions?
No, the insert is designed for fixed flow settings and is not suitable for systems that require variable flow control. It is intended for use in pre-balanced systems where the flow rate is set at the time of installation.

Is the insert compatible with all IVAR valves?
No, the 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 types.

Can the insert be adjusted after installation?
No, the insert does not have an external adjustment mechanism. Once installed, the flow setting is fixed and cannot be changed without removing the insert and replacing it with a different model.

What is the maximum operating temperature for the insert?
The insert is rated for operation up to +120 °C. It is suitable for use in hot water systems but should not be used in applications with higher temperatures than specified.
