Automatic balancing valve ASV-PV with capillary tube, size 100DN, pre-setting range 0.2-0.4bar 003Z0625

Automatic balancing valve – precise flow control

This automatic ASV-PV balancing valve with capillary tube, with a nominal diameter of DN 100, is a key component in heating and air conditioning systems. Its task is to maintain optimal medium flow, which translates to thermal comfort and energy efficiency of the installation. This valve is particularly useful in systems with radiators and fan coil units, where precise flow adjustment is crucial for proper operation.

The ASV-PV valve is characterized by a pre-setting range of 0.2-0.4 bar, which allows it to be adapted to the specific hydraulic conditions of the installation. This makes it possible to balance the heating circuits without the need for manual flow adjustment each time changes occur in the system. This saves time and guarantees stable operation of the installation.

Construction and application

The valve is made of cast iron GG 25 (GJL-250), which ensures its durability and corrosion resistance. It has flanged connections with a pressure class of PN 16, which facilitates installation in existing installations. The built-in impulse tube allows connection to a pressure gauge or pressure regulator, enabling precise measurement and control of the valve's operating parameters.

ASV-PV valves are widely used in:

• Heating systems: Ensure even heat distribution throughout the building.
• Air conditioning installations: Maintain optimal temperature and humidity.
• Systems with fan coil units and air handling units: Precise control of the cooling or heating medium flow.
• New and modernized installations: Adaptability to different hydraulic configurations.

Key features and benefits

• Automatic regulation: Maintains a constant differential pressure, regardless of flow changes in the installation – eliminates the need for manual system balancing.
• Wide adjustment range: Adjustment range of 20-40 kPa allows for precise adaptation to different operating conditions.
• Durable construction: Made of cast iron GG 25 ensures long-lasting and reliable operation even in difficult operating conditions.
• Easy installation: Flanged connections facilitate integration with existing installations with a diameter of DN 100.
• High Kvs value (76): Provides high flow capacity, minimizing pressure loss in the installation.
• Serviceability: The valve has a shut-off function to facilitate servicing and replacement of installation elements.
• Temperature resistance: Designed for continuous operation at temperatures up to 120°C – possibility of use in various types of heating systems.
• Maximum differential pressure at 20°C is 250 bar, which guarantees safe operation even in installations with high working pressure.
