Set KLASIK DYNAMIC - straight, 1/2"

Product detailed description

Dynamic balancing radiator valve sets are essential components in modern hydronic heating systems, particularly in residential and commercial buildings where precise flow control and system efficiency are required. Installers and system designers often encounter scenarios where individual radiators need to be balanced to ensure even heat distribution and prevent overloading of the pump. This is especially relevant in systems with multiple zones or where retrofitting older installations with modern control systems is necessary. The IVAR KIT501187 set is specifically designed for such applications, offering a complete solution for 1/2 inch steel pipe connections.

By integrating dynamic balancing, this set allows for automatic adjustment of flow rates in response to system changes, ensuring consistent performance and energy efficiency. The pre-set Kv value simplifies initial setup, while the modular design allows for easy integration into existing or new installations. The nickel-plated brass construction ensures durability and resistance to corrosion, making it suitable for long-term use in heating systems.

Technical parameters

Installation and connection

Installation of the IVAR KIT501187 set involves connecting the valve to a steel pipe using the M30 x 1.5 thread on the valve head. The set is pre-assembled with the DD 301 actuator, T 5000 temperature sensor, and VD 2101 NH valve body, which simplifies the installation process. The installer must ensure that the pipe is clean and free of debris before fitting the valve. A common mistake is incorrect thread engagement, which can lead to leaks or improper sealing. It is also important to verify that the Kv value is correctly set according to the system's design flow rate. The valve should be mounted in a position that allows for easy access for future adjustments or maintenance.

Compatibility and accessories

This valve set is designed for use with steel piping and is compatible with standard heating systems that operate within the specified pressure and temperature ranges. No additional accessories are required for basic installation, as the set includes all necessary components. However, in more complex systems, additional balancing tools or control units may be needed. The IVAR KIT501187 is intended for use with the specified components and is not interchangeable with other valve types without verification of compatibility.

Technical background for designers

The operating principle of the IVAR KIT501187 set is based on dynamic flow balancing, which adjusts the flow rate in response to changes in system demand. The nickel-plated brass CW617N body ensures long-term durability and resistance to thermal and mechanical stress. The integration of the temperature sensor allows for real-time monitoring and adjustment of the flow to maintain optimal system performance. The efficiency and service life of the valve are influenced by the quality of the installation, the cleanliness of the system, and the regularity of maintenance checks. Proper sizing according to the system's hydraulic requirements is essential to avoid overloading the pump or underperforming radiators.

Service and operation

Regular inspection of the valve set is recommended to ensure continued performance. The main checkpoints include verifying the tightness of the connections, checking for signs of corrosion or wear, and ensuring that the Kv value remains correctly set. No specific service intervals are provided in the brief, but it is advisable to inspect the system during routine maintenance. If the system shows signs of imbalance or reduced efficiency, the valve can be adjusted or recalibrated as needed. The modular design allows for individual components to be replaced without removing the entire set from the system.

Frequently asked questions

Can the IVAR KIT501187 be connected to copper or plastic piping?
According to the technical specifications, the set is designed for steel pipe connections. Connection to other pipe materials should be verified for compatibility with the M30 x 1.5 thread and the sealing properties of the valve.

Is the Kv value adjustable after installation?
The set includes a pre-set Kv value, which can be adjusted during installation according to the system's flow requirements. No further adjustments are mentioned in the brief.

Can the temperature sensor be replaced separately?
The set includes the IVAR T 5000 temperature sensor as part of the pre-assembled components. Replacement of individual parts should be verified with the manufacturer's technical documentation.

What is the maximum operating temperature of the valve set?
The maximum operating temperature is specified as 120°C, which is suitable for standard heating system applications.
