## Summary description

Angled thermostatic radiator valve by INVENA, model IECD-74-K15, designed for regulating hot-water heating radiators. Features an angled body, presetting function for flow regulation and a compact (mini) thermostatic head for temperature control. Suitable for residential and light commercial heating systems where space is limited and precise radiator balancing is required.

## Long description

Angled thermostatic radiator valve INVENA IECD-74-K15 with presetting and a mini thermostatic head is designed for regulating temperature and flow in hot-water heating radiators. The compact angled body allows installation in confined spaces and on radiators with side connections, while the presetting feature lets installers balance radiators by limiting maximum flow. The mini thermostatic head provides accurate automatic temperature control by reacting to ambient temperature changes and adjusting the valve position accordingly.
Advantages
The angled configuration saves space and facilitates tidy piping runs on wall-mounted radiators. Presetting enables precise hydraulic balancing during installation, reducing noise and uneven heating. The mini thermostatic head offers compact dimensions without sacrificing control accuracy, making it suitable where a full-size head would obstruct furniture or décor. The valve is compatible with standard hot-water central heating systems and designed for reliable, repeatable operation.
Suitable for
 Residential radiators with side/angled connections
 Rooms with limited clearance where a compact head is needed
 Hydraulic balancing of multi-radiator heating systems
 Light commercial spaces with conventional hot-water heating
Key specifications
 Valve orientation: angled (90°)
 Control type: thermostatic with mini head
 Flow control: presetting function for limiting/maximising flow
 Application: hot-water central heating radiators
 Material and finish: corrosion-resistant valve body suitable for heating water (manufacturer standard)
 Compact dimensions: space-saving design for tight installation zones
How to use
Mount the valve on the radiator inlet according to radiator and pipework configuration, ensuring the angled body aligns with the supply/return piping. Use the presetting mechanism during installation to set the desired maximum flow for hydraulic balancing across multiple radiators. Attach the mini thermostatic head and set the required room temperature on the head’s scale; the head will automatically modulate the valve to maintain the selected temperature. Regularly check for leaks after installation and follow building heating system commissioning procedures.
Usage recommendations
For optimal performance, perform hydraulic balancing during initial system commissioning and re-check after any significant changes to the heating circuit. Avoid obstructing the thermostatic head with curtains or furniture to ensure accurate ambient temperature sensing. Use the presetting feature to reduce excessive flow and improve comfort and energy efficiency.
