## Long description

Thermostatic radiator valve set kfa² 1/2" model 757-000-07-BL, angled/straight connection options is a valve assembly for controlling the temperature of hot-water radiators in central heating systems. The set includes a valve body configured for either angled or straight installation and a connection for a thermostatic head, enabling automatic regulation of flow according to the selected room temperature. It is designed for 1/2" pipe connections and intended for use on standard residential and commercial radiators where accurate temperature control and heat regulation are required.
Advantages
The valve set provides automated temperature control by accepting a thermostatic head, which adjusts hot-water flow to maintain the desired room temperature. Its compatibility with both angled and straight connection arrangements allows flexible installation to suit different radiator types and piping layouts. Constructed for use with 1/2" supply lines, the design supports reliable sealing and stable operation in typical central heating conditions.
Suitable for
Domestic radiators in apartments and houses
Commercial radiator installations in offices and small businesses
Replacement of manual radiator valves with thermostatic control
Systems requiring individual-room temperature regulation and energy management
Key specifications
Connection size: 1/2" suitable for standard radiator supply pipes
Connection orientation: angled and straight options for installation flexibility
Thermostatic head interface: standard mounting for compatible thermostatic actuators
Intended medium: hot water used in central heating systems
Application: compatible with residential and light commercial radiator types
How to use
Install the valve body on the radiator inlet using the appropriate angled or straight orientation to match the existing pipework. Secure connections to the 1/2" supply pipe and attach a compatible thermostatic head to the valve’s head connection according to the head manufacturer’s instructions. After installation, set the desired temperature on the thermostatic head; the valve will modulate flow automatically to reach and maintain that temperature. Ensure the heating system is depressurized and drained as required before fitting, and check for leaks after commissioning.
Usage recommendations
Use a thermostatic head compatible with the valve’s interface and follow the head manufacturer’s calibration guidance. For reliable operation, have installation and first commissioning performed by a qualified heating technician and perform routine checks for leaks and proper modulation, especially after seasonal start-up.
