Automatic balancing valve ASV-PV with capillary tube, size 80DN, preset range 0.35-0.75 bar 003Z0634

Automatic balancing valve – precision and efficiency in heating and air conditioning systems

This automatic balancing valve ASV-PV, with a nominal diameter of DN 80, is a key element in ensuring optimal heat or cool flow in installations. This valve, manufactured by Danfoss, is designed for mounting on the return line and automatically regulates the flow of medium, eliminating problems associated with uneven temperature distribution. This ensures the system operates more efficiently and operating costs are lower.

Design and application

The ASV-PV valve is characterized by a solid construction of cast iron GG 25 (GJL-250), which guarantees its durability and corrosion resistance. Equipped with a capillary tube, it works with the MSV-F2 valve (available separately) allowing precise setting of the differential pressure in the range of 0.35 to 0.75 bar (35 to 75 kPa). This makes the valve ideally suited for use in heating installations with radiators and fan coil units. Its flanged connection (DN 80) ensures tightness and ease of installation.

These types of valves are particularly useful in systems with underfloor heating manifolds, where maintaining a constant differential pressure is crucial for even heat distribution. Thanks to automatic regulation, the need for manual balancing of the installation after each configuration change is eliminated.

Key features and benefits

• Automatic regulation: The valve automatically adjusts the medium flow to current operating conditions, ensuring optimal thermal comfort and energy savings.
• Precise setting: The ability to set the differential pressure in the range of 0.35-0.75 bar allows the valve to be adapted to the specific requirements of the installation.
• Durable construction: Made of cast iron GG 25 guarantees long life and corrosion resistance.
• High Kvs value: A Kvs value of 48 ensures high flow rate and minimal pressure loss.
• Easy installation: The flanged connection facilitates installation and ensures a tight connection.
• Membrane control: Provides smooth and precise flow regulation.
• Shut-off function: Allows cutting off the medium flow for maintenance or repair.
• With impulse tube: Allows measurement of differential pressure and control of valve operation.

The ASV-PV valve is an investment in user comfort and building energy efficiency. Its reliability and precision of operation translate into long-term savings and user satisfaction.
