Thermostatic radiator valves
Thermostatic radiator valves are essential components in hydronic heating systems, enabling precise temperature regulation in individual rooms. These valves control the flow of heated water into radiators based on ambient temperature, ensuring energy efficiency and comfort. The category includes classic models, versions for ladder systems, axial designs, EC (electronic control) variants, and single-point armatures. They are commonly used in residential and commercial buildings with wet heating systems, such as those with panel radiators, underfloor heating, or fan convectors.
These valves operate by adjusting the flow of hot water in response to temperature changes. When the room reaches the setpoint, the valve reduces or stops the flow to maintain the desired temperature. They are typically installed on the inlet side of the radiator and require a manual or automatic actuator for adjustment.
How to choose
- Choose the correct connection type and size (e.g., G 1/2" or M30x1.5) to match the radiator and piping system.
- Select a model compatible with the system type, such as ladder, axial, or EC-controlled systems.
- Consider the material of the valve body and actuator for durability and corrosion resistance in wet environments.
- Ensure the valve is suitable for the operating pressure and temperature range of the heating system.
- Verify compatibility with existing control systems or actuators if retrofitting or upgrading an existing installation.
Frequently asked questions
Can thermostatic valves be used with underfloor heating systems?
Yes, provided the valve is designed for low-flow applications and has a compatible actuator.
How do I adjust the temperature setting on a thermostatic valve?
Most models feature a manual adjustment dial or a digital interface for setting the desired room temperature.
Are thermostatic valves suitable for use with condensing boilers?
Yes, as long as the valve supports the required flow rates and temperature ranges for condensing operation.

Thermostatic radiator heads classic, for ladders, EC and axial.
Thermostatic valves for radiators. By using thermostatic valves in heating systems, the temperature of rooms is individually regulated and thus energy savings are achieved. They are characterized by noiseless and reliable operation. The valve only lets in as much water into the radiator as is necessary to maintain the set temperature.
