## Summary description

Angled radiator valve CALEFFI model 431402 with 1/2" connection, designed for use in central heating radiator installations. The valve provides angled connection between pipework and radiator, enabling flow control and reliable sealing in heating circuits. Suitable for domestic and light commercial radiator systems where a 1/2" angled valve is required.

## Long description

Angled radiator valve CALEFFI 431402 1/2" is a compact control fitting designed for central heating radiator installations. The valve provides an angular connection between the radiator and supply/return pipework with a 1/2" thread, allowing smooth flow regulation and tight shut-off in domestic and light commercial systems. Constructed for compatibility with standard radiator inlet fittings, the valve supports routine balancing and maintenance of heating circuits.
Advantages
The valve offers reliable sealing and stable flow adjustment in a compact angled body that simplifies installation where space is limited. Its 1/2" connection makes it suitable for common radiator piping, and the design reduces stress on joints by aligning the radiator and piping at a convenient angle. Materials and finishing are selected for corrosion resistance and long service life under typical heating conditions.
Suitable for
Domestic radiator installations with 1/2" connections
Light commercial heating systems
Replacement of angled radiator valves in existing circuits
Applications requiring compact angled connections where wall or floor space is restricted
Key specifications
Connection type: angled 1/2" thread to match standard radiator valves and pipe fittings
Function: flow control and shut-off for radiator circuits
Material characteristics: corrosion-resistant metal body suitable for heating medium
Installation orientation: angled connection to align radiator and piping
Compatibility: designed for central heating radiators and typical heating circuit pressures and temperatures
How to use
Install the valve at the radiator inlet using the appropriate 1/2" threaded connection and tighten to recommended torque values to ensure a leak-free joint. Connect the valve to the supply or return pipework in the correct orientation for angled alignment. Use the valve spindle to adjust flow for balancing the radiator; fully close the valve when isolating the radiator for maintenance. After installation, inspect joints and perform a pressure test in accordance with local codes and the heating system manufacturer’s instructions.
Usage recommendations
For reliable operation, perform periodic visual checks for leaks and corrosion, and operate the valve gently when adjusting flow. Use compatible sealing materials (thread tape or approved joint compounds) on threaded connections and follow system fill and bleed procedures to remove air from the circuit.
