Measuring and draining fitting - for balancing valve - 5/4"; Kv 16,63 IVAR.CIM 721

Product detailed description

This measuring and draining fitting is commonly used in heating systems where accurate flow measurement and controlled draining are required. It is typically installed in conjunction with balancing valves to ensure even heat distribution across building zones. Installers working on residential, commercial, or industrial heating systems will find this fitting essential for system balancing and maintenance. The fitting is suitable for use in central heating systems, underfloor heating, and other hydronic applications where precise flow control is necessary.

Correct selection and installation of this fitting are crucial for maintaining system efficiency and preventing issues such as uneven heating or excessive pressure drops. The fitting is designed to integrate seamlessly with standard balancing valves and is compatible with a wide range of pipe sizes and configurations.

Technical parameters

Installation and connection

Installation of the IVAR 721114 involves connecting it to a balancing valve using the 5/4 inch thread. Ensure that the connection is clean and free of debris before tightening the fitting to prevent leaks. Use a wrench to secure the fitting, but avoid over-tightening, which can damage the threads or the valve body. Check that the fitting is aligned with the valve and that there is no misalignment that could cause stress on the connection.

Common installation mistakes include using the wrong thread type or not verifying the compatibility with the balancing valve model. Always confirm the specifications of the valve before installation. Additionally, ensure that the system is depressurised before beginning work to avoid injury or equipment damage.

Compatibility and accessories

This fitting is specifically designed for use with the IVAR.CIM 727 balancing valve. When ordering, ensure that the balancing valve is also available to complete the system. No additional accessories are required for standard installation, but it is recommended to have sealing tape or thread compound on hand to ensure a leak-free connection.

Technical background for designers

The fitting operates by allowing controlled flow measurement and draining when used in conjunction with a balancing valve. The CW602N-M brass material provides good thermal conductivity and resistance to corrosion, making it suitable for use in both hot and cold water systems. The PN 20 rating ensures that the fitting can handle the typical pressures found in heating systems without failure. The integration of this fitting into the system helps to maintain balanced flow and reduce the risk of over- or under-pressurisation in different zones.

The service life of the fitting is influenced by the quality of the installation, the operating conditions, and the maintenance schedule. Regular inspection and cleaning can help to extend its lifespan and maintain system efficiency.

Service and operation

During operation, the fitting requires minimal maintenance. However, it is recommended to inspect the connection periodically for signs of wear or leakage. If any issues are detected, the fitting should be removed and inspected for damage. No specific service intervals are required for this fitting, but it is good practice to check it during routine system maintenance.

Frequently asked questions

Can the IVAR 721114 be connected to a balancing valve with a different model number?
No, this fitting is specifically designed for use with the IVAR.CIM 727 balancing valve. Using it with a different model may result in compatibility issues or improper function.

What is the maximum operating temperature for this fitting?
The maximum operating temperature is +120°C. Exceeding this temperature may affect the performance and integrity of the fitting.

Is sealing compound required for installation?
Sealing compound or thread tape is recommended to ensure a leak-free connection, especially in high-pressure applications. However, it is not mandatory for all installations.

Can this fitting be used in a closed-loop system?
Yes, the IVAR 721114 is suitable for use in closed-loop systems where balancing and draining functions are required. Ensure that the system pressure does not exceed the PN 20 rating.
