## Summary description

Angle thermostatic valve by Comap, model R858624, designed for 1/2" connections with M28 preset spindle. This thermostatic radiator valve provides temperature regulation at the radiator inlet and features a factory-set preset to limit flow during commissioning. Suitable for residential and commercial heating systems where compact angle installation and reliable temperature control are required.

## Long description

Angle thermostatic valve Comap R858624 1/2" with preset M28 is a compact radiator valve designed for right-angled installation on 1/2" connections. The valve integrates a thermostatic control spindle compatible with M28 heads and a factory-applied preset that limits the maximum flow during system commissioning. It is intended for use in residential and commercial hot-water heating systems where precise inlet temperature control and a small footprint at the radiator connection are required.
Advantages
This angle thermostatic valve offers stable temperature regulation at the radiator inlet thanks to its thermostatic spindle compatible with M28 actuators. The factory preset simplifies commissioning by setting a maximum flow limit, reducing the need for manual balancing during initial setup. Its compact 90° angle body allows installation where space is limited and supports reliable operation in standard domestic and light commercial heating circuits.
Suitable for
 Radiator connections with 1/2" threads requiring an angle valve
 Systems using M28 thermostatic heads or compatible actuators
 Residential apartment and single-family home heating systems
 Light commercial heating installations where compact components are needed
Key specifications
 Connection type: angle (90°) for 1/2" pipe fittings
 Thermostatic spindle interface: M28-compatible
 Factory preset: adjustable preset spindle to limit maximum flow at commissioning
 Body material: corrosion-resistant metal suitable for hot-water heating
 Application: hot-water central heating radiators
How to use
Install the valve at the radiator inlet with the angle body oriented to match the pipe run, ensuring correct sealing of the 1/2" connections. Fit an M28 thermostatic head onto the spindle according to the head manufacturer's instructions. Use the preset spindle to set the desired maximum flow during system commissioning; this limits the radiator flow and helps achieve hydraulic balance. After setting the preset, operate the thermostatic head to regulate local room temperature.
Usage recommendations
Inspect sealing surfaces and use appropriate thread sealing materials during installation. During commissioning, adjust the preset gradually while monitoring radiator temperature and system pressure to achieve balanced heating. Use thermostatic heads compatible with M28 threads for full functionality and replace the valve if signs of corrosion or leakage appear.
