Manual balancing valve with possibility of expansion to automatic version USV-I, size DN 25 003Z2133

Manual balancing valve – flexibility and precision in one

The USV-I balancing valve is a reliable solution for precise flow control in heating and cooling systems. Made of brass, it ensures durability and corrosion resistance. Its design allows for later expansion to an automatic version, providing flexibility to adapt to changing system needs. It is ideal for both new installations and the modernization of existing ones.

This valve is equipped with internal metric threads (both connections), which facilitates installation and integration with various installation elements. It also has a drain, which allows for safe emptying of the circuit during servicing or maintenance. The pressure class PN 16 guarantees safe operation under standard operating conditions.

Characteristics and application

The USV-I valve is designed for manual flow regulation of liquids in heating and cooling systems. A Kvs value of 4 indicates its performance and ability to handle medium flows. The maximum pressure difference of 150 bar ensures stable operation even in demanding conditions. The possibility of expanding to an automatic version is a significant advantage – it avoids the need to replace the entire valve when automation of regulation is required.

• Durability: The brass housing provides corrosion resistance and long life.
• Flexibility: The ability to expand to an automatic version allows the valve to be adapted to future system needs.
• Precision: Manual operation allows for accurate adjustment of liquid flow.
• Safety: The drain facilitates maintenance and servicing of the installation, and the pressure class PN 16 ensures safe operation.
• Wide temperature range: Continuous operation in the temperature range from 120°C to 120°C allows for use in various heating systems.

This valve is used in central heating installations, air conditioning systems, and industrial processes requiring precise flow control of liquids. It is a solid choice for both professional installers and end-users looking for a reliable solution for hydraulic balancing of installations.
