Thermostatic Radiator Valve Set No name ZTO30AT — anthracite axial thermostatic head and valve set

The thermostatic radiator valve set No name ZTO30AT combines an axial thermostatic head and matching valve in an anthracite finish for direct temperature control of hot-water radiators. Designed to be fitted to the radiator connection, the compact assembly provides local regulation of flow and automatic modulation of heat output according to the room temperature sensed at the valve head. The set is intended for residential and light commercial heating systems where a space-saving axial configuration and a durable metal finish are required.

Advantages

The anthracite axial thermostatic head and valve set offers stable proportional control over radiator flow without the need to operate the central boiler manually. Its compact axial design reduces protrusion from the radiator connection, allowing installation in confined spaces and behind furniture. The metal valve body and finished head provide increased mechanical durability and a uniform appearance that matches contemporary radiator styles. The thermostatic element reacts to ambient temperature changes to modulate flow, improving comfort and supporting energy-efficient operation when used as part of a balanced heating system.

Suitable for

• Hot-water radiators in apartments and houses
• Light commercial rooms such as offices and meeting rooms
• Renovations where a compact axial valve is required
• Applications requiring visible, coordinated finish in anthracite

Key specifications

• Configuration: axial thermostatic valve set with matching head
• Finish: anthracite
• Application: hot-water radiator temperature regulation
• Control type: thermostatic proportional modulation based on ambient temperature at the head
• Installation position: inline at radiator connection (axial orientation)
• Compatibility: intended for standard radiator connections in residential and light commercial systems

How to use

Install the valve set at the radiator inlet following the radiator and pipework manufacturer instructions and applicable plumbing standards. Fit the valve body into the radiator connection, ensure proper sealing, and attach the axial thermostatic head. Once the system is filled and bled of air, set the desired room temperature by turning the thermostatic head to the required setting. The thermostatic element will open or close the valve to maintain the set temperature by regulating the hot-water flow through the radiator.

Usage recommendations

For accurate temperature control and long service life, avoid covering the thermostatic head with curtains or furniture that block ambient airflow. Commission the valve as part of a balanced heating system; ensure correct pipework orientation and proper radiator venting. Periodic visual inspection and, if accessible, occasional operation through the full travel of the head help prevent sticking and ensure reliable modulation.
