Thermostatic Radiator Valve Head DANFOSS Redia M30x1.5 with Built-in Sensor, Setpoint 0

Thermostatic radiator valve head DANFOSS Redia M30x1.5 with built-in sensor and mechanical setpoint marked “0” is a compact control element for radiator valves. It is designed for direct mounting on M30x1.5 valve bodies to regulate room temperature by controlling hot water flow through radiators. The integrated temperature sensor provides local sensing close to the valve, enabling simple and reliable automatic temperature regulation without external wiring or remote sensors.

Advantages

The valve head offers straightforward mechanical setpoint adjustment with a clear “0” reference, enabling easy set-up and operation. Its built-in sensor eliminates the need for separate temperature probes or electrical connections, simplifying installation and reducing potential points of failure. The compact design is compatible with standard M30x1.5 valve bodies and provides consistent control suitable for residential and light commercial heating systems.

Suitable for

• Individual radiator temperature control in apartments and houses
• Light commercial spaces such as offices or small retail premises
• Retrofit projects where direct-mount thermostat heads are required
• Systems where simple, local temperature regulation without wiring is preferred

Key specifications

• Mounting thread: M30x1.5 compatible with standard radiator valve bodies
• Built-in temperature sensor for local measurement
• Mechanical setpoint with “0” marking for reference
• Compact housing suitable for direct valve head replacement
• Intended for use in hot water radiator heating systems

How to use

Mount the DANFOSS Redia valve head directly onto a compatible M30x1.5 radiator valve body and tighten according to the valve manufacturer's instructions. Set the mechanical setpoint using the marked “0” position as a reference and adjust to the desired room temperature. The built-in sensor will measure local temperature and modulate valve opening to maintain the selected setpoint by regulating water flow through the radiator. No electrical connection is required.

Usage recommendations

Install only on valve bodies with an M30x1.5 thread and verify compatibility with the radiator valve stem before fitting. Avoid placing the valve head where direct drafts, sunlight, or heat sources could affect local temperature sensing. Periodically check operation for smooth movement and correct temperature response, and follow standard maintenance procedures for radiator valves.
