Regulating valve, 2-way VB2, KVS=4 stroke 5 065B2056

Danfoss VB2 regulating valve is a reliable solution for precise flow control in heating and cooling systems. Designed to work with AMV(E) actuators, it ensures optimal performance in central heating, domestic hot water and HVAC systems. Made of durable cast iron GGG 40, it guarantees long-term operation even in demanding conditions.

Characteristics and application

The VB2 valve, thanks to its hydraulically relieved design, minimizes the impact of pressure changes on the accuracy of regulation. This is particularly important in systems with large load fluctuations, where stable maintenance of operating parameters is crucial. Designed for mounting with flanges, it simplifies integration with existing pipeline infrastructure. A Kvs value of 4 m³/h and a stroke of 5 mm allow for precise adjustment of the flow to current needs. The ability to use with AMV(E) 10/20/30 or AMV(E) 13/23/33 actuators increases the flexibility of the installation.

Construction and parameters

The valve body is made of high-quality cast iron GGG 40, which ensures corrosion resistance and long life. Internal elements, such as the mushroom and seat, made of stainless steel further increase durability and resistance to the action of chemical agents present in the circulating water. Pressure class PN 25 guarantees safe operation in installations with increased working pressure - up to 16 bar in the open position. Leakage at the level of 0.05% of the Kvs value minimizes energy losses and ensures efficient system operation. Nominal connection diameter DN 15 allows the valve to be used in installations with medium flow rates.

• Durable housing made of cast iron ensures solidity and corrosion resistance.
• Kvs coefficient of 4 m³/h enables optimal flow in typical heating and cooling applications.
• Valve stroke of 5 mm provides precise flow regulation.
• Pressure class PN 25 guarantees safe operation at elevated working pressure up to 16 bar.
• Low leakage (0.05% Kvs) minimizes energy losses and increases system efficiency.
• The valve is used in heating installations, central heating, domestic hot water preparation and HVAC systems.
• Compatible with AMV(E) 10/20/30 and AMV(E) 13/23/33 actuators, which facilitates integration with building automation.

The VB2 valve is a proven choice for professionals and users looking for a reliable and efficient solution for flow control in their installations.
