## Summary description

Axial thermostatic radiator valve INVENA CD-25-C15 in black finish. Designed to regulate flow and temperature in hot-water radiators, this thermostatic valve fits axial connections and provides manual control of radiator output. Suitable for residential and commercial heating systems where an axial mounting and compact, dark-colored valve body are required.

## Long description

The INVENA CD-25-C15 axial thermostatic radiator valve in black is designed for regulating flow and temperature in hot-water radiator systems. Its axial configuration fits installations where inlet and outlet pipe alignment is straight-through, and the dark finish integrates with modern interior trims. The valve provides manual adjustment of radiator output and works with compatible thermostatic heads or can be used as a manual control when a head is not attached.
Advantages
The axial design simplifies installation where pipework aligns along a straight axis, reducing the need for additional fittings. The black finish offers a discreet appearance that matches contemporary radiators and interior hardware. The valve body is engineered for stable temperature regulation and reliable sealing to minimise leaks and maintain system efficiency.
Suitable for
Residential hot-water radiator systems with axial pipe connections
Commercial heating installations requiring compact, dark-coloured valve hardware
Retrofit projects where visual coordination with black fixtures is desired
Applications that use separate thermostatic heads or manual valve control
Key specifications
Configuration: axial (straight-through) valve
Function: thermostatic radiator flow and temperature regulation
Finish: black
Control: compatible with thermostatic heads or manual operation
Intended medium: hot water for heating systems
Application: radiators in residential and commercial buildings
How to use
Mount the INVENA axial thermostatic valve in line with the radiator inlet and the connecting pipework so that flow passes straight through the valve body. If using a thermostatic head, attach the appropriate head to the valve spindle according to the head manufacturer’s instructions; if using the valve manually, operate the control spindle to adjust flow and radiator temperature. After installation, purge air from the radiator and check for leaks. Adjust settings as required to achieve the desired room temperature.
Usage recommendations
For reliable operation, use the valve with compatible thermostatic heads rated for radiator applications and follow system commissioning procedures such as flushing and de-aeration. Regular inspection and occasional operation of the spindle will help prevent sticking. If the system uses high mineral content water, follow local guidelines for water treatment to reduce risk of internal scale.
