Radiator valve set DANFOSS 2-piece straight with RAE-K actuator and VKO connection module for panel radiators

Two-piece straight radiator valve set DANFOSS with RAE-K actuator and VKO connection module is designed for accurate flow regulation and room temperature control on panel radiators. The set combines a straight supply valve and a matching return valve with a pre-mounted VKO connection module, enabling secure attachment to compatible radiators and simple integration with central heating systems. The included RAE-K electronic/thermostatic actuator provides precise temperature-driven valve control to maintain set room temperatures and improve comfort.

Advantages

The straight two-piece design allows compact installation on panel radiators while maintaining stable hydraulic performance. The RAE-K actuator offers reliable electronic/thermostatic control, reducing temperature fluctuations and enabling energy-efficient operation when used with a compatible control system. The VKO connection module ensures correct alignment and leak-free connection to radiators from major manufacturers, facilitating installation and service access.

Suitable for

• Panel radiators from manufacturers with compatible connection geometry
• Residential and light-commercial central heating systems
• Retrofitting or replacing existing straight valve sets on panel radiators

Key specifications

• Configuration: two-piece straight valve set with supply and return valves
• Actuator type: electronic/thermostatic RAE-K actuator for temperature-controlled operation
• Connection module: VKO mounting module for secure radiator interface
• Application: designed for panel radiators and connection to central heating systems
• Control function: modulating on/off or proportional control according to actuator design

How to use

Mount the VKO connection module to the radiator according to the radiator manufacturer’s instructions, ensuring correct alignment and sealing. Install the two-piece straight valve set onto the radiator connections, then attach the RAE-K actuator to the valve head. Connect the actuator electrically if required by the model and configure the desired room temperature or control mode following the actuator manual. Perform a pressure and leak test after installation and balance the system as needed to achieve intended room temperatures.

Usage recommendations

Use this DANFOSS valve set on panel radiators with matching VKO connection geometry. For optimal performance, follow the actuator commissioning procedure, ensure system flushing and filtering before installation, and have hydraulic balancing carried out by a qualified technician when integrating into existing central heating systems.
