## Long description

Herz TS-90 straight thermostatic radiator valve with 1/2" connection is designed to regulate room temperature by controlling the flow of hot water to a radiator. The valve provides precise thermostatic control for individual radiators in central heating systems, enabling stable temperature maintenance and contributing to energy-efficient heating management in residential and commercial installations.
Advantages
The thermostatic mechanism responds to ambient temperature changes to maintain the set level without manual adjustment. A straight configuration with a 1/2" connection ensures compatibility with common radiator pipework and simplifies installation on inline supply or return lines. Durable construction and a compact form factor offer reliable operation in typical heating system conditions while minimizing the space required by the valve assembly.
Suitable for
 Individual radiator temperature control in central heating systems
 Retrofit upgrades where a 1/2" straight valve connection is required
 Residential apartments, single-family houses, and small commercial spaces
 Rooms where precise room-level thermostatic control is needed for comfort and energy savings
Key specifications
 Valve type: thermostatic radiator valve, straight design
 Connection size: 1/2" (compatible with standard 1/2" radiator fittings)
 Function: automatic modulation of hot water flow according to ambient temperature
 Installation orientation: inline (straight) for supply or return piping
 Application: central heating systems for individual radiator control
How to use
Install the valve in-line with the radiator inlet or outlet using compatible 1/2" fittings, ensuring pipework is depressurised before beginning work. Fit an appropriate thermostatic head to the valve body and set the desired temperature level on the head. After installation, bleed the radiator to remove trapped air and check for leaks. The valve will automatically adjust water flow to maintain the selected room temperature; occasional manual checks and calibration of the thermostatic head may be performed to ensure consistent performance.
Usage recommendations
For reliable operation, use with properly balanced heating systems and compatible thermostatic heads from the same product family or those recommended by the valve manufacturer. Periodically inspect for leaks and ensure the thermostatic head sensor is not obstructed by furniture or curtains to allow accurate temperature sensing.
