Regulating valve VF2, KVS=145, STROKE 30 065B3205

Control valve for heating and cooling systems

The VF2 control valve is a reliable solution for precise flow control in water installations, both heating and – to a limited extent – cooling. The design based on the principle of a mushroom valve with a logarithmic characteristic ensures stable operation and effective temperature control. This element is particularly recommended for use with various types of actuators, providing great flexibility in choosing the optimal solution for a specific application.

Construction and application

The VF2 valve is characterized by a solid construction with a cast iron body, which guarantees durability and corrosion resistance. Flanged connections with a nominal diameter of DN100 and a pressure class of PN16 ensure tightness and easy installation in existing systems. The Kvs value of 145 m³/h indicates a high flow rate, making it suitable for use in systems with higher performance. The valve stroke of 30 mm allows for precise adjustment of the flow to current needs.

This valve is primarily used in:

• Central heating systems,
• Heating installations in residential and industrial buildings,
• Domestic hot water distribution systems,
• Applications requiring precise liquid flow control.

Key features and benefits

• High flow rate: The Kvs coefficient of 145 m³/h allows for efficient flow of the working medium. This translates to a quick response of the system to changes in heat or cooling demand.
• Durable construction: The cast iron body provides corrosion resistance and long valve life, even in harsh operating conditions.
• Precise regulation: The logarithmic characteristic ensures stable and accurate flow control, allowing for maintaining optimal temperature in the rooms.
• Versatility: Compatibility with various types of actuators (AMV(E) 55, 56, 423, 523) increases installation flexibility and facilitates integration with existing control systems.
• Safety: The pressure class PN16 guarantees safe operation of the valve in installations with increased working pressure. The maximum differential pressure in the open position is 1.5 bar.
• Resistance to external factors: The valve is designed to operate with media at temperatures from 2°C to 130°C and allows the use of antifreeze agents up to 50%.
