Three-way valve with actuator VST 11 for up to 30kW 27858

Three-way valve with actuator – a key element of efficient heating

The three-way valve with actuator, model VST 11, is an indispensable component in domestic hot water heating systems, especially in configurations with NIBE F1345 heat pumps. Its task is to precisely control the flow of the heating medium, which translates into optimal energy utilization and user comfort. It is required when the NIBE F1345 heat pump works with VPA tanks.

Application and compatibility

This valve is designed to work with heat pumps with a maximum compressor power of up to 17 kW (for VST 11). This ensures proper system operation and efficient water heating. This is particularly important in installations where precise temperature control and energy consumption optimization are required. The valve allows you to direct heat to the appropriate zones in the building, increasing the efficiency of the entire heating system.

Construction and principle of operation

The three-way valve with actuator operates on the principle of switching the heat flow. The actuator, controlled by the heat pump control system, changes the direction of the heating medium flow, allowing it to be directed to different receivers – e.g. to a hot water buffer or directly to the heating installation. This design allows for flexible adaptation of the system to current needs and weather conditions. Precise flow control ensures stable temperature and minimizes energy losses.

Advantages for the installer and end user

• Easy installation: The valve is designed to work with existing NIBE installations, which facilitates its installation and integration with the system.
• High control accuracy: The actuator provides accurate regulation of the heating medium flow, which translates into optimal system operation and energy savings.
• Reliability: High-quality components guarantee long-lasting and trouble-free operation of the valve.
• Cost optimization: Thanks to efficient energy use, the heat pump works more efficiently, reducing heating costs.
• Compatibility: The valve has been specifically designed to work with NIBE F1345 heat pumps and VPA tanks, ensuring full compatibility and optimal system performance.
• Increased comfort: Stable domestic hot water temperature ensures high comfort throughout the year.
