## Long description

Thermostatic Angled Set CALEFFI KIT4220402 1/2" is an angled thermostatic valve assembly designed for regulation of radiator temperature in central heating systems. The kit is intended for installation at the radiator inlet in an angled configuration, providing direct control of heat output and enabling hydraulic balancing between radiators. It is suitable for both residential and commercial radiator installations where thermostatic control is required.
Advantages
The angled thermostatic valve provides precise temperature regulation at the radiator, improving comfort and energy efficiency. Its compact angled design allows installation in confined spaces or where a straight valve is impractical. The product is designed for compatibility with standard 1/2" radiator connections and supports hydraulic balancing to ensure even heat distribution across the heating circuit.
Suitable for
Domestic radiators in apartments and houses
Commercial radiator installations in offices and public buildings
Systems requiring thermostatic control and hydraulic balancing
Replacement of existing angled radiator valves with 1/2" connections
Key specifications
Connection type: angled inlet designed for 1/2" radiator connections
Function: thermostatic temperature control for radiator circuits
Installation position: angled mounting on radiator inlet
Application: central heating systems for residential and commercial use
Primary benefit: enables temperature regulation and hydraulic balancing
How to use
Install the angled thermostatic valve on the radiator inlet according to installation guidelines and local plumbing codes, ensuring the valve face matches the radiator connection orientation. Connect the valve to the heating pipework with appropriate fittings for a 1/2" connection and purge the system to remove air before commissioning. After installation, set the thermostatic head (if supplied separately) to the desired temperature value and verify proper operation by checking that the radiator heats and balances with the rest of the system.
Usage recommendations
For reliable operation, use the valve within the specified temperature and pressure limits of the heating system, perform regular maintenance checks for leaks and correct movement of the thermostatic element, and follow manufacturer instructions for replacing the thermostatic head or cartridge. When replacing an existing valve, confirm compatibility of dimensions and thread types to avoid fittings mismatch.
