Automatic balancing valve ASV-PV 5-25 kPa 50 003Z0611

Automatic balancing valve – precision and efficiency in heating systems

This automatic balancing valve ASV-PV, with a nominal diameter of DN 50 and a regulation range of 5-25 kPa, is a key element in the hydraulic balancing of heating installations. Designed by Danfoss, it combines reliable operation with ease of use, resulting in energy savings and user comfort. This valve is particularly recommended for use with radiators, where precise flow adjustment is crucial for optimal heat distribution.

Construction and application

The ASV-PV valve is mounted on the return line of the heating installation, working with a corresponding valve mounted on the supply line. Its task is to maintain a constant pressure difference in the circuit, regardless of flow changes. This ensures even heating of all rooms, eliminating problems with underheated or overheated zones. The built-in drainage function and the possibility of flushing the installation before start-up increase the reliability of the entire system. The cast iron housing guarantees durability and corrosion resistance. The metric external thread (G 2 1/2 A) facilitates installation and connection to the existing installation.

Key features and benefits

• Automatic regulation: The valve automatically adjusts the flow to current operating conditions, eliminating the need for manual adjustment and monitoring.
• Wide adjustment range: The pressure differential setting range of 5-25 kPa allows for precise adaptation to the specifics of the installation and user needs.
• High accuracy: The pressure differential setting is linear and easy to read, ensuring precise flow control.
• Locking function: The ability to lock the adjustment ring prevents accidental changes to the settings by unauthorized persons.
• Efficiency: A Kvs value of 20 provides adequate flow for installations with a diameter of DN 50.
• Durability: Made of high-quality materials (cast iron) guarantees long life and corrosion resistance.
• Ease of servicing: Integrated service functions (draining, flushing) facilitate maintenance and repairs.
• Compatibility: Can be used with various cooperating valves (ASV-BD, ASV-I, ASV-M).
• Suitable temperature range: Continuous operation in a temperature range of 120°C allows for use in most standard heating systems.

The ASV-PV valve is an investment in comfort and savings – both for the end user and for the installer responsible for the proper functioning of the heating system. Thanks to precise flow control, energy consumption can be significantly reduced and even heat distribution throughout the building can be ensured.
