## Long description

Sourcing R402H is a thermostatic radiator valve engineered for automatic temperature regulation of heating radiators. The valve features a female 1/2" connection and an M30×1.5 cap thread for standard thermostatic heads. It controls radiator flow to maintain a set room temperature and is intended for domestic and small commercial central heating systems, radiator replacements, and retrofit projects.
Advantages
The valve provides automatic modulation of water flow according to room temperature, reducing the need for manual adjustment. Its female 1/2" connection and M30×1.5 cap thread ensure compatibility with common radiator fittings and many thermostatic heads. The compact angle valve design saves space near wall-mounted radiators and simplifies installation during repairs or system upgrades.
Suitable for
Domestic central heating radiators where automatic temperature control is required
Small commercial premises with radiator heating systems
Radiator replacement or retrofit projects that use 1/2" female connections and M30×1.5 thermostatic heads
Heating systems seeking individual room temperature regulation to improve comfort and efficiency
When it may not be suitable
This valve is not suitable for installations that require connection types other than a 1/2" female fitting or for radiators that use a different cap thread standard. It is intended for typical low- to medium-pressure central heating systems; it may not be appropriate for high-pressure industrial systems or applications requiring specialized corrosion-resistant materials not specified for this model.
Key specifications
Connection type: female 1/2"
Cap thread: M30×1.5 (for thermostatic heads)
Valve type: angle thermostatic radiator valve
Function: automatic flow modulation to maintain set room temperature
Typical application: domestic and small commercial central heating radiators
How to use
Install the valve by replacing the existing radiator valve or fitting it to the radiator inlet with the female 1/2" connection. Attach a compatible thermostatic head to the M30×1.5 cap thread, set the desired room temperature on the thermostatic head, and allow the valve to regulate water flow automatically. Commission the system by bleeding radiators and checking for leaks. Adjust the thermostatic head settings as needed to achieve the required comfort level.
What to consider before purchase
Verify radiator inlet connection size is 1/2" female
Confirm thermostatic head compatibility with M30×1.5 cap thread
Ensure the valve type (angle) fits the radiator orientation and available space
Check system pressure and materials compatibility for your heating installation
Usage recommendations
For reliable operation, mount a compatible thermostatic head, purge the heating system after installation, and perform periodic checks for leaks and smooth valve movement. When replacing an existing valve, compare dimensions and clearance to ensure the angle valve aligns correctly with pipes and the radiator inlet.
