Three-way valve with actuator VST 20 for up to 40kW 27859

Three-way valve with actuator – the key to efficient heating control

The three-way valve with actuator, model VST 20, is an essential component in heating systems using NIBE heat pumps, especially in configurations with VPA tanks. Its task is to precisely control the flow of heating medium, which translates into optimal use of the heat pump's power and thermal comfort in the building. The device is dedicated to installations with a power of up to 40 kW, making it a universal solution for both single-family homes and larger facilities.

Application and compatibility

The VST 20 valve is designed to work with NIBE F1345 heat pumps. It is a key component in systems where it is necessary to switch the heat circuit between different receivers – for example, between central heating and domestic hot water preparation. This makes it possible to effectively use energy and adapt the system to current needs. Compatibility with pumps up to 40kW makes the valve widely applicable in various heating installations.

Construction and benefits for the installer and user

The VST 20 three-way valve is characterized by a solid construction and precise operation of the actuator. Installation and connection of the device is relatively simple, which translates into time savings during installation. For the end user, this means stable operation of the heating system, optimal energy consumption and the ability to efficiently control the temperature in the rooms. Thanks to precise flow control, the valve helps avoid energy losses and reduce heating system operating costs. Additionally, it improves user comfort by providing a stable temperature in the rooms and access to domestic hot water at the right temperature.
