## Long description

FERRO ZTV20 is a thermostatic radiator valve set supplied with a GT20 thermostatic head, designed for temperature regulation in central heating systems. The compact valve body and separate control head enable precise setting of room or circuit temperature where an underfloor heating connection or radiator inlet needs thermostatic control. The set is suitable for replacing existing valves or for new installations in domestic heating circuits, providing straightforward mechanical control of flow to maintain desired temperatures.
Advantages
The valve set combines a compact, robust valve body with an interchangeable GT20 thermostatic head to offer dependable temperature control without electronic components. Its design allows for straightforward installation on underfloor heating manifolds or radiator connections and supports accurate proportional regulation of flow according to the thermostat setting. The separate head is easy to mount and adjust, and the overall assembly is engineered for long-term operation in typical residential heating conditions.
Suitable for
Domestic central heating systems with underfloor heating connections
Radiator inlet temperature control where space is limited
Replacement of existing mechanical thermostatic control points
Heat distribution manifolds and small heating circuits
Key specifications
Thermostatic valve set with separate control head for proportional temperature regulation
Included manual thermostatic head model GT20 for direct temperature setting
Compact valve body suitable for installation on manifolds and radiator inlets
Mechanical, non-electronic operation for straightforward maintenance
Materials and construction suitable for typical residential heating media and temperatures
How to use
Install the valve set on the heating circuit at the radiator inlet or underfloor heating manifold following standard plumbing practice and ensuring system pressure is isolated before work. Fit the GT20 head onto the valve spindle and secure according to the manufacturer’s mounting method. Adjust the thermostatic head to the required setting to control the flow through the valve and thus regulate the temperature of the connected heating circuit. After installation, bleed the circuit if needed and verify correct operation across the expected temperature range.
Usage recommendations
Use the FERRO ZTV20 set in domestic heating systems with compatible pipework and fittings. For reliable performance, avoid exposing the thermostatic head to direct drafts, strong sunlight, or encasement that prevents free air circulation. Periodically check the valve and head for secure mounting and normal movement; follow local codes and best practices for installation and maintenance.
