## Summary description

DANFOSS MTCV 20 is a thermostatic multi-functional valve designed for temperature control in heating systems. The MTCV 20 integrates thermostatic regulation and valve functions to control flow and maintain set temperatures. Suitable for integration in radiators, convectors or hydronic circuits where compact thermostatic flow control is required.

## Long description

DANFOSS MTCV 20 is a thermostatic multi-functional valve designed for precise temperature control in hydronic heating systems. The unit combines a thermostatic regulator with an integrated valve body to control flow and maintain set temperatures in radiators, convectors and compact heating circuits. Its compact design allows installation where space is limited while delivering consistent temperature regulation and flow control suitable for residential and light-commercial applications.
Advantages
The MTCV 20 integrates thermostatic sensing and valve operation into a single compact device, reducing the number of separate components required in a heating loop. It provides stable temperature control through automatic modulation of flow, helping to maintain comfort levels and system efficiency. The unit is compatible with common radiator and convector installations and is engineered for straightforward mounting and reliable operation over time.
Suitable for
Domestic radiators and convectors where individual room temperature control is needed
Compact hydronic circuits with limited installation space
Retrofit projects to replace or upgrade conventional valve and thermostat combinations
Zones in light commercial heating systems requiring thermostatic flow control
Key specifications
Thermostatic multi-functional valve with integrated temperature sensing and flow control
Compact valve body suitable for installation on radiators, convectors and small manifolds
Designed for hydronic heating systems and room-level temperature regulation
Mechanical modulation of flow based on setpoint and sensed temperature
Materials and construction intended for long-term operation in heating circuits
How to use
Install the MTCV 20 in place of the existing valve assembly or on a compatible connection using appropriate fittings and sealing methods. Set the desired room temperature on the valve’s control head according to the manufacturer’s instructions; the valve will modulate flow automatically to maintain the setpoint. Ensure the system is filled, bled of air and operating at correct pressures before commissioning. Regularly check for leaks and proper movement of the valve mechanism during the first weeks of operation.
Usage recommendations
For reliable performance, pair the MTCV 20 with properly sized radiators or convectors and maintain the hydronic system according to standard service intervals. Avoid aggressive cleaning agents on the valve head and protect the sensing element from direct sunlight or external heat sources to ensure accurate temperature sensing.
