## Summary description

FERRO GT33B is a thermostatic radiator valve head with a liquid-filled sensor in antracite finish. Designed to replace or upgrade manual radiator valves, it regulates room temperature by sensing coolant temperature and adjusting valve position. Suitable for domestic and commercial central heating systems; fits compatible thermostatic valve bodies for automated temperature control.

## Long description

FERRO GT33B liquid sensor thermostatic radiator valve head in antracite is designed to provide automated temperature regulation for central heating radiators. The valve head detects the temperature of the radiator coolant via an internal liquid sensor and modulates the valve position to maintain the set room temperature. Its antracite finish offers a neutral aesthetic that suits modern and traditional interiors while replacing manual radiator control with a thermostatic solution compatible with standard thermostatic valve bodies.
Advantages
The FERRO GT33B features a liquid-filled sensing element that provides stable and precise temperature feedback, reducing oscillations compared with some air-sensor heads. Its compact design and antracite surface ensure discreet installation and corrosion resistance appropriate for domestic and commercial heating systems. The valve head is intended for easy mechanical attachment to compatible thermostatic valve bodies, enabling automated control without altering the heating system plumbing.
Suitable for
Automatic temperature control of radiators in homes and apartments
Upgrading manual radiator valves in offices and small commercial spaces
Replacement of existing thermostatic heads on compatible valve bodies
Key specifications
Sensor type: liquid-filled temperature sensor for radiator coolant detection
Finish: antracite (dark grey)
Control: thermostatic modulation of valve position based on sensed temperature
Mounting: designed to fit compatible thermostatic valve bodies (mechanical attachment)
Application: central heating radiators in domestic and commercial settings
How to use
Install the FERRO GT33B by removing the existing manual or thermostatic head from a compatible valve body and attaching the GT33B according to the valve manufacturer's mounting method. Set the desired room temperature using the head's setting mechanism; the liquid sensor will respond to changes in radiator coolant temperature and move the valve to increase or decrease flow. Regularly check the mechanical connection for secure fitting and ensure the valve body is compatible before installation. For maintenance, wipe the external surface with a soft cloth and avoid using aggressive chemicals that could damage the finish.
Usage recommendations
Use the FERRO GT33B with valve bodies designed for thermostatic heads and verify compatibility prior to purchase. Avoid forcing the head onto incompatible fittings. For best performance, allow free airflow around the head and do not cover with curtains or furniture that could affect temperature sensing.
