## Summary description

Valvex Thermostatic Head GZ.03 (4410000) is a radiator thermostat head designed to regulate room temperature by controlling valve flow. Compatible with thermostatic radiator valves, it provides adjustable temperature control for central heating systems. Intended for residential or commercial radiators, it facilitates energy management and more precise indoor climate control.

## Long description

Valvex Thermostatic Radiator Head GZ.03 is a compact thermostatic control head designed to regulate room temperature by adjusting flow through compatible radiator valves. Intended for use with standard thermostatic radiator valves, this thermostat head enables proportional control of heating output in individual rooms, improving temperature stability and supporting energy-conscious operation in residential and light commercial central heating systems.
Advantages
The thermostatic head offers precise temperature control through a user-adjustable setpoint that modulates the valve opening as room conditions change. Its straightforward mechanical design requires no external power and integrates directly onto compatible valve bodies, ensuring reliable operation with minimal maintenance. The compact form factor and clear scale markings make adjustment simple, while the unit's compatibility with common valve types permits retrofit or replacement use on many radiators.
Suitable for
Individual room temperature control in apartments and houses
Upgrading or replacing existing radiator thermostatic heads
Energy management in small commercial premises with central heating
Zoned heating installations where separate radiator control is required
Key specifications
Type: Mechanical thermostatic radiator head
Control: Adjustable temperature setpoint with graduated scale
Power: Self-actuating, no external power required
Compatibility: Designed for use with standard thermostatic radiator valve bodies
Installation: Direct mount onto compatible valve spindles
Build: Compact form factor suitable for standard radiator environments
How to use
Mount the thermostatic head onto a compatible valve following the valve manufacturer's instructions, ensuring the valve spindle is clean and undamaged. Rotate the control head to the desired setpoint according to room comfort needs; the head will automatically modulate the valve to maintain the selected temperature. Allow a travel period for the room to stabilize after adjustments and avoid covering the head or placing it in direct drafts, which could affect sensing accuracy.
Usage recommendations
For best performance, install the thermostatic head on radiators in representative locations for each room and keep furniture or curtains clear of the sensing element. When replacing an existing head, confirm mechanical compatibility with the valve body. Periodically check for smooth operation and, if needed, clean the valve spindle before refitting to ensure reliable modulation and long service life.
