Automatic balancing valve ASV-PV 5-25 kPa DN25, without insulation - 4TH GENERATION 003Z5503

Automatic balancing valve – precision and efficiency in heating systems

This fourth-generation ASV-PV automatic balancing valve is a key element for hydraulic balancing in two-pipe heating systems. Its function is to maintain a stable differential pressure in the circuits, eliminating problems with uneven heat distribution, noise, and excessive energy consumption. This valve, with a nominal diameter of DN25, is ideal for use in systems with variable flow, ensuring optimal performance at both full and partial load.

Design and operating principle

The ASV-PV valve combines a differential pressure regulator (mounted on the return pipe) with a cooperating valve (mounted on the supply pipe), connected by an impulse tube. This design enables precise control of the differential pressure on the radiator riser. The integrated membrane ensures optimal performance even at low flow rates and high sensitivity to pressure changes. The valve body is made of composite material and the spring is located outside the working medium, increasing its durability and corrosion resistance. Additionally, the ability to flush the installation before starting the valve increases the reliability of the entire system.

Advantages for installers and users

• Quick installation and commissioning: The fourth generation of ASV-PV has been designed with the convenience of installers in mind – its small dimensions make it easy to install in tight spaces. A clear setting scale allows for quick and precise adjustment of the differential pressure without the need for additional tools.
• High regulation accuracy: The Δp setting range of 5-25 kPa is ideally suited for heating systems with radiators, ensuring optimal operating parameters. Metal-to-metal sealing (valve mushroom and seat) guarantees reliable regulation even at low flow rates.
• Energy saving: Hydraulic balancing of the installation thanks to ASV-PV translates into reduced energy consumption and lower heating costs.
• Durability and reliability: The use of high-quality materials and a corrosion-resistant design ensure long-lasting and trouble-free operation of the valve.
• Setting lock function: The integrated locking function prevents accidental changes to the settings by unauthorized persons.
• Wide operating temperature range: The valve retains its properties in the temperature range from -10 to +120°C, making it a universal solution for various types of installations.
• Easy servicing: The replaceable spring allows you to adjust the setting range to the specific needs of the system without having to replace the entire valve.

The valve has metric internal threads on both connection side 1 and 2 and a pressure class of PN 16, with a Kvs value of 4. The product height is 197 mm. The material is other (according to ETIM data).
