Check valve ASV-PV, DN50, 5-25 kPa, threaded (female thread), with insulation 003Z5606

Check valve for precise hydraulic balancing of the installation. This ASV-PV check valve, with a nominal diameter of DN50 and an adjustment range of 5-25 kPa, is a key component in heating and air conditioning systems. Designed for automatic flow balancing, it ensures optimal operation of each circuit, regardless of its length or resistance. Made of brass and cast iron GG25, it guarantees durability and corrosion resistance. Thermal insulation minimizes heat loss and prevents condensation.

The ASV-PV valve is particularly recommended for use with radiators, where precise setting of the differential pressure (Δp) is crucial for thermal comfort. The adjustment range of 5-25 kPa allows adaptation to specific installation conditions. The built-in impulse tube allows easy pressure measurement and valve operation control.

Design and practical application

The valve has internal threaded connections (Metric internal thread), which facilitates installation and integration with the existing installation. Its solid construction of brass and cast iron ensures reliability even in harsh working conditions – it withstands a continuous operating temperature of up to 120°C and a maximum differential pressure of 150 kPa. Control is carried out using a key, allowing precise setting of the desired differential pressure.

The ASV-PV valve finds application in:

• Heating systems: automatic balancing of radiator circuits, ensuring uniform temperature distribution.
• Air conditioning installations: regulation of refrigerant flow in fan coil units and induction units.
• Ventilation systems: balancing airflow in ventilation ducts.
• New installations: hydraulic optimization from the very beginning, ensuring efficient system operation.
• Modernized installations: improving the efficiency of existing systems by precisely balancing the circuits.

Additionally, this valve is compatible with other elements of the Danfoss system, such as cooperating valves ASV-M/I/BD (for DN 15-50) or MSV-F2 (for DN 65-100), allowing you to create a comprehensive solution for hydraulic regulation of the installation. Remember to install the valve on the return line, and the cooperating valve on the supply line – this is key to the correct operation of the entire system! The Kvs value of 16 ensures adequate flow for medium-sized installations.
